ABAP RAP - Managed scenario - Create Supplier invoice by Action using EML and I_SUPPLIERINVOICETP

[jindrich_sustr_cz]

Dear all,

I'm quite new in ABAP RAP, I love it I hate it 😀

I'm developing an application in RAP + UI, where users put some external additional informations about a business document. This application is developed in ABAP RAP, managed scenario.

I'd like to have following scenario:

User put some additional information into UI and create / update custom business object (let's say incomming supplier invoice - detail info.)

I have validation and determination there.

In validation I check if additional data are OK and in determination I change internal state code of this business object (this works)

Save data (this works)

After save, I'm using feature control to enable action for business object with some state code (for example '01' = data complete. (this works)

But here comes a problem.

I'd like to be able to create a Supplier invoice with purchase order reference by using EML using I_SUPPLIERINVOICETP in Action method of my BO.

  action ( features : instance ) createSupplierInvoice result [1] $self;

METHOD createSupplierInvoice.

DATA ls_invoice TYPE STRUCTURE FOR ACTION IMPORT i_supplierinvoicetp~create.
DATA lt_invoice TYPE TABLE FOR ACTION IMPORT i_supplierinvoicetp~create.
DATA ld_sinv_item_id TYPE n LENGTH 6 VALUE '1'.

TRY.
  DATA(ld_cid_invo_hdr) = cl_uuid_factory=>create_system_uuid( )->create_uuid_x16( ).
  CATCH cx_uuid_error.
 ENDTRY.

*lt_incinvappr = table with additional data
READ TABLE lt_incinvappr ASSIGNING FIELD-SYMBOL(<ls_incinvappr>) INDEX 1.

  ls_invoice-%cid = ld_cid_invo_hdr.
  ls_invoice-%param-supplierinvoiceiscreditmemo   = abap_false.
  ls_invoice-%param-companycode                   = <ls_incinvappr>-CompanyId.
  ls_invoice-%param-invoicingparty                = <ls_incinvappr>-SupplierId.
  ls_invoice-%param-postingdate                   = <ls_incinvappr>-IssueDate.
  ls_invoice-%param-documentdate                  = <ls_incinvappr>-IssueDate.
  ls_invoice-%param-documentcurrency              = <ls_incinvappr>-Currency.
  ls_invoice-%param-invoicegrossamount            = <ls_incinvappr>-GrossAmount.
  ls_invoice-%param-taxiscalculatedautomatically  = abap_true.                      
  ls_invoice-%param-SupplierInvoiceIDByInvcgParty = <ls_incinvappr>-ExternalId.
  ls_invoice-%param-DocumentHeaderText            = 'SAP RAP Action'.
  ls_invoice-%param-TaxDeterminationDate          = <ls_incinvappr>-TaxDate.
  ls_invoice-%param-DueCalculationBaseDate        = <ls_incinvappr>-DueDate.
  ls_invoice-%param-SupplierInvoiceStatus         = cl_mmiv_rap_ext_c=>supplierinvoicestatus-held.

* lt_purchaseorder_item = table with PO reference items
  LOOP AT lt_purchaseorder_item ASSIGNING FIELD-SYMBOL(<ls_pur_item>).

    APPEND VALUE #( supplierinvoiceitem = ld_sinv_item_id
                    purchaseorder       = <ls_incinvappr>-OrderNumber
                    purchaseorderitem   = <ls_pur_item>-PurchaseOrderItem
                    documentcurrency    = <ls_incinvappr>-Currency
                    supplierinvoiceitemamount   = <ls_pur_item>-NetAmount
                    purchaseOrderQuantityUnit   = <ls_pur_item>-PurchaseOrderQuantityUnit
                    quantityinpurchaseorderunit = <ls_pur_item>-OrderQuantity
                    taxcode                     = 'V1'
                          )

    TO ls_invoice-%param-_itemswithporeference.
          ld_sinv_item_id = ld_sinv_item_id + 1.
  ENDLOOP.

  INSERT ls_invoice INTO TABLE lt_invoice.

* Create BO - Supplier invoice with PO ref

  MODIFY ENTITIES OF I_SupplierInvoiceTP PRIVILEGED
    ENTITY SupplierInvoice
    EXECUTE Create FROM lt_invoice

    FAILED      DATA(ls_sinvoice_create_failed)
    REPORTED    DATA(ls_sinvoice_create_reported)
    MAPPED      DATA(ls_sinvoice_create_mapped).

ENDMETHOD.

It simply doesn't work. I'm doing my best, but there is something which i don't understand or don't see.

I know that there can not be any Commit Entities to not to corrupt LUW. But how should I create Supplier Invoice from UI using button with action?

How can i get number of created supplier invoice - there is late numbering and I know that i have to convert %pid to key. But what is uncleare to me where. Additional Save? 

Is there any key / best practise how to use EML? I can create sales order in action method by EML and I_SALESORDERTP. But not supplier invoice. Why? What is the best practise for this scenario? How should I create supplier invoice in RAP?

Best regards,

Jindrich

Hi Jindrich, did you solve your issue?

[jindrich_sustr_cz]

Hi Giuseppeg, unfortunately there is no standard solution for this except a workaround.

I had to redesign an application and use event, local event consumption, bgPF and that is solution which works. But count with the fact, that events are part of SAVE sequence.

Omg. why there is no possibity for "Non modifiying action" where we could raise an event as asynchronous process. C'mon even javascript got Promises.

I work with SAP ABAP RAP for the whole year very intensively and I have to say it is somewhere in between. There is a massive gap between "old" ABAP development and this new approach and even bigger between ABAP RAP and other "cloud" usable dev. languages / frameworks.

As I work on SAP Public cloud project I have to say it is super annoing to ask someone to release this and that (CDS). That is not how a real world works and is it very stressful to explain it to a customer.

But it is what it is.

Hey SAP experts, do you check community? We are speaking about State of the art technology SAP ABAP RAP.

[giuseppeg]

We are building an app which posts supplier invoices using i_supplierinvoicetp or i_journalentrytp based on user choice.

We are able to retrieve the FI document number posted by i_journalentrytp; BO i_supplierinvoicetp seems to run differently.

Could you share your workaround?

Thank you and I wish you a happy new year 🙂
