S4HCKS40 - Create MRP Areas from Excel by leveraging API's

In this snippet we re-visit a previously released snippet : S4HCKS23 Mass Processing Product Master changes in SAP S/4HANA Cloud, but this time leveraging an API that is called from the comfort of MS Excel.

The underlying objective of this snippet, is to show how easy it is to leverage our API’s from third party applications, not just in Read mode, but also in Create/Update Modes. In this snippet we show you how you can supplement your Product Masters with MRP Areas, but this coud apply to any other of the available API’s.

As indicated in the recording, I am providing the excel used in the recording, for you to try out and get some inspiration from. As a disclaimer : You can use it at your own risk – I take no responsibility for you using it. I encourage to first try it in your Q system, with a small dataset. I also remind you not to pass this file to others with either data and / or login credentials !

Some of the important links covered in the recording are:

I must also give credit to Philip Hoffmann, who’s blog provided the file that I have also used to kick start this project. Phillip’s blog also covers how to create a communication user.

I encourage you to read the ‘Read Me First’ tab to get some valuable information, but if you want to just dive right in after you have created your communication user, then you just need to maintain the data you want to upload (MRP_RECORDS tab) and the login credentials as shown below (in the EXEC_DATA tab)

S4HCKS34 Manage your production capacity effectively

In this SAP S/4HANA Cloud Knowledge Snippet – #S4HCKS – we do a deep dive into a new Fiori Application that was released with SAP S/4HANA Cloud 1808. The app in question is Manage Work Center Capacity. You can find more information about this application in the Fiori Apps Library by following this link. You can also check out the application documentation here. If you are unsure where to start to begin exploring this application your self, then Best Practices scope item 31L – Production Capacity Planning and Evaluation– is a good start.

I will let you follow the video for a detailed walkthrough of you need to do in SAP S/4HANA Cloud to be able to fully leverage this application, but before that I will just offer a few pointers, that are also discussed in the recording .

Generate capacity requirements for planned orders

This is not a must and really depends on your situation – i.e is capacity an issue and are you always juggling with the capacity of your bottleneck or key work stations. If so, then you may wish to generate capacity requirements for your planned orders already coming out of MRP, so that you have visibility over the capacity requirement of your production plan over a longer horizon, then that just provided just by the production orders (which you would have only created when needed !).

If so, then you will want to execute the scheduled MRP run, with the scheduling setting ‘2’ – Detailed scheduling. This will have the effect of reading the product’s routing and not not the in-house production lead time in the material! Because you are reading the routing, it means that you are reading the routing’s work centres.

Is your formula enabled to generate capacity requirements?

The formula you will choose in the work centre (or create yourself) is very important, in that, if you miss the setting that will generate a capacity requirement, then you will not see any capacity in the capacity monitoring application! So make sure the ‘WKCtr for rqmts’ check box is active for your selected formula!

Tailor the system to your needs

It may be that you need to create your own formulas, to calculate the capacity requirements of your work centers using a specific formula. No problem, with SAP S/4HANA Cloud you can do that! Just head over the to the Manage your solution application, look for the SSCUI’s in the context Manufacturing / Shop Floor Control / Work Center and create your own formulas.

S4HCKS29 Real World solutions with S/4HANA Cloud to real World problems

The stated requirement was to be able to have a KPI tile in the Fiori Launch Pad, that would show a count of the customers that had been able to reach one of two (or both) sales tiers. A sales tier being a sales volume. The numbers are not realistic, but let’s say that tier 1 would represent customers that had been able to reach a sales volume of 1000USD and tier 2 would represent customers that had been able to reach a sales volume of 2000USD. This volume had to be reached over a specific period of time, and if the customer reached one of the two tiers, over that specified period of time, he would then be eligible for a credit (or a rebate if you prefer). The higher the tier achieved, the greater the credit issued. As you can see, using standard features of S/4HANA Cloud, this was achieved quite easily.

The next requirement, was to be able to drill down to a graphical representation of these sales volumes and clearly highlight the two sales tiers (1000USD and 2000USD), so as to be able to instantaneously visualise which customer had reached these tiers. Again, as you can see below, this and much more was achieved using standard capabilities of S/4HANA Cloud. Not only were we able to build the desired graphical representation of the sales volumes and sales tiers, we also added mini charts (mini KPI’s) as well as various evaluations, so as to be able to slice and dice the information in various ways.

So far, the customer brief was met. However, thinking about the use of this data, it quickly becomes evident that the next steps to be taken on the basis of this data, is to be able to issue the due credit to the eligible customers – but how are you going to do it? From the app above, it is possible to present the data in tabular form, you could even add calculated fields in the evaluation of your KPI tile to calculate things such as the amount of the credit. You could also export the data to a spreadsheet and there also calculate the credit due. Then, you are left with the need to create the credit memo in the system. Whilst of course possible, this is fraught with risks (badly slicing the data could lead to over/under issuing credits) and of course immensely tedious – imagine someone entering a large amount of documents in the system manually (again fraught with risks). That said, thanks to S/4HANA Cloud and the power of extensibility there is a much better, faster and leaner way to do this.

What we did, was to use the ‘Custom Business Object’ in S/4HANA Cloud to define a new object – Sales Volumes tiers. The custom business object allows you to define the structure of the object that you need as well as the fields that define this object. In our case we needed fields that would pertain to customers, (customer ID, name, sales organisation…), tiers information (the volume that needed to be achieved as well as the % of the credit that would be issued). Lastly we also wanted to restrict how the volume was going to be measured. I.e was all the customer’s business going to count, or did we want to restrict by a set of materials or materials groups for example. We chose the material group. A snapshot of part of the structure of our Custom Business Object is shown below.

Once the custom business object was created, we then used some coding to realise the magic of the process, namely, to call a CDS to sum the amounts billed to the customer, and on the basis of that determine the amount of the credit to be issued to the customer (if eligible). Then we perform a second call to a whitelisted API to actually create the credit to the customer.

I will let you watch the video recording below to give you a complete view of what we did, but at a high level, in bullet point form below are the main steps/functions:

Creates a custom business object with the required structure and fields.
We added validation logic to make sure the data entered was correct, as expected and was going to play nicely with the subsequent processes
We added some logic, to call the CDS I_BillingDocumentItemCube so as to sum the sales volume of the considered customer.
One the basis of the sales volume determined, and based on the sales targets of the customer, we determine if the customer achieved the Tier 1 or Tier 2 target and if he did, we calculate the corresponding amount of the credit he earned.
We then make a POST call to the whitelisted API API_CREDIT_MEMO_REQUEST_SRV, to actually create the credit memo in the S/4HANA Cloud system.
Looking at these steps, you can imagine the level of automation that was achieved as well as the added value offered!

Code Snippets & how-to's

Please check out the blog from my colleague Arun here : https://blogs.sap.com/2018/06/13/mass-update-using-sap-s4hana-cloud-in-app-extensibility/ . His blog will show you what you need to do to setup the required communication arrangements. I would like to thank Arun for his wonderful blog which provided the missing pieces to mine as well as his pointers along the way.

All code provided below is provided as-is. You take full responsibility for using as it nowhere near production grade code.

Below is the code for the first action. It retrieves the sales volumes from the billing CDS and works out the credit due to the customer.

 

* Action Calculate for Node ID sales_volume_rebate
*
* Importing Parameter : association (Navigation to Parent/Child/Associated Node Instances)
* Changing Parameter : sales_volume_rebate (Current Node Data)
* Exporting Parameter : message (Message with Severity S(uccess), W(arning), E(rror))

* -----------------------------------------------------------------------
* calculate bonus
*
DATA: netamount TYPE P DECIMALS 2.
DATA: internetamount TYPE P DECIMALS 2.
DATA: bonus1 TYPE P DECIMALS 2.
DATA: bonus2 TYPE P DECIMALS 2.

IF salesvolumestiers-releasestatus GT '2'.
IF salesvolumestiers-isconsistent = abap_true.

" calculate product bonus
DATA: products TYPE TABLE OF i_productgroup.
DATA: product LIKE LINE OF products.

* get product list from sub node Products
DATA(bonusproducts) = association->to_materialgroups( ).

" get net amount for product
LOOP AT bonusproducts INTO DATA(bonusproduct).
SELECT *
FROM i_productgroup
INTO @product
WHERE i_productgroup~materialgroup = @bonusproduct-materialgroups-materialgroupid.
ENDSELECT.

SELECT
FROM I_BillingDocumentItemCube( p_exchangeratetype = 'M', p_displaycurrency = 'USD' )
FIELDS SUM( SlsVolumeNetAmtInDspCrcy )
WHERE creationdate BETWEEN @salesvolumestiers-validfrom AND @salesvolumestiers-validto
AND SalesOrganization = @salesvolumestiers-salesorg
AND soldtoparty = @salesvolumestiers-soldtoparty
AND materialgroup = @bonusproduct-materialgroups-materialgroupid
INTO @internetamount.

netamount = internetamount + netamount.

ENDLOOP.

salesvolumestiers-volumeachieved_v = netamount.
salesvolumestiers-volumeachieved_c = 'USD'.

if netamount LT salesvolumestiers-targetrevenue1_v.
salesvolumestiers-calculatedbonus_v = 0.
elseif netamount GT salesvolumestiers-targetrevenue2_v.
salesvolumestiers-calculatedbonus_v = ( ( netamount / 100 ) * ( salesvolumestiers-bonusrate2 ) ).
salesvolumestiers-calculatedbonus_c = 'USD'.
else.
salesvolumestiers-calculatedbonus_v = ( ( netamount / 100 ) * ( salesvolumestiers-bonusrate1 ) ).
salesvolumestiers-calculatedbonus_c = 'USD'.
endif.

salesvolumestiers-releasestatus = 4.

ENDIF.
ENDIF.
* SAP CODE BELOW

message = VALUE #(
severity = co_severity-success
text = 'Action CalculateCustomerCredit executed'
).

Then the next piece of code is that which is used create the credit memo per se. Again you will want (have to!) add your own error handling code and execution logic.

* Action CreateCreditMemo for Node ID SALESVOLUMESTIERS
*
* Importing Parameter : association (Navigation to Parent/Child/Associated Node Instances)
* write (API for creating and updating Custom Business Object Node Instances)
* Changing Parameter : SALESVOLUMESTIERS (Current Node Data)
* Exporting Parameter : message (Message with Severity S(uccess), W(arning), E(rror))

CHECK cl_ble_http_client=>is_service_available(
communication_scenario = 'YY1_INT_HTTP'
outbound_service = 'YY1_INT_HTTP_REST'
) = abap_true.

DATA(lo_client) = cl_ble_http_client=>create(
communication_scenario = 'YY1_INT_HTTP'
outbound_service = 'YY1_INT_HTTP_REST'
).

* we get the csrf token to be able to make the POST call later
DATA(request) = cl_ble_http_request=>create( ).
DATA lv_s2 TYPE string VALUE '/API_CREDIT_MEMO_REQUEST_SRV/A_CreditMemoRequest?%24top=1&%24format=json'.
request->set_header_parameter( exporting name = 'X-CSRF-TOKEN' value = 'FETCH' ).

TRY .
DATA(response) = lo_client->send( request ).
DATA(lv_csrf) = response->get_header_parameter( 'x-csrf-token' ).
CATCH cx_ble_http_exception INTO DATA(l5).
ENDTRY.

* We build the payload that will be submitted in the POST call
* We will also convert the calculated bonus to a string so that the call plays nicely
DATA: lv_payload TYPE string,
calcbonus TYPE string,
lv_pl41 TYPE string value '{"d" : { "PurchaseOrderByCustomer": "CREDIT-2018- ',

lv_pl46 TYPE string value '"ConditionType":"PPR0","ConditionRateValue": "',
lv_pl47 TYPE string value '","ConditionCurrency":"',
lv_pl48 TYPE string value '"} ] } ] } }'.

* We retrieve the calculated bonus from the custom business object
calcbonus = salesvolumestiers-calculatedbonus_v.
* We get rid of the trailing space that is added to the calculated bonus
CONDENSE calcbonus.

* we concatenate the various fields that will make up the payload
CONCATENATE lv_pl41 salesvolumestiers-soldtoparty lv_pl42 salesvolumestiers-soldtoparty lv_pl43
salesvolumestiers-salesorg lv_pl44 lv_pl45 lv_pl46

salesvolumestiers-calculatedbonus_c lv_pl48 INTO lv_payload.

* we make the POST call to the credit memo request API
DATA(request1) = cl_ble_http_request=>create( ).

request1->set_header_parameter( exporting name = 'x-csrf-token' value = lv_csrf ).
request1->set_content_type( 'application/json' ).
request1->set_method( 'POST' )->set_resource_extension( lv_s1 ).
request1->set_body( lv_payload ).

TRY .
DATA(response1) = lo_client->send( request1 ).
CATCH cx_ble_http_exception INTO DATA(lx1).
ENDTRY.

* We also want to be able to update the custom business object with the created credit memo number
* So we will use regular expressions to find the content of the tag in the response
DATA result TYPE match_result_tab.
DATA line LIKE LINE OF result.
DATA sub TYPE submatch_result.
DATA output TYPE string.
DATA lx60 TYPE string.
output = response1->get_body( ).

FIND ALL OCCURRENCES OF REGEX '((?:[^<]| LOOP AT result INTO line.
LOOP AT line-submatches INTO sub.
lx60 = output+sub-offset(sub-length).
ENDLOOP.
ENDLOOP.

* We update the custom business object field Credit Memo with the credit memo number just created
salesvolumestiers-creditmemo = lx60.

message = VALUE #(
severity = co_severity-success
text = 'Credit Memo Created:'
&& lx60
).
