How to handle multiple commit relevant changes in a RAP object

[#1]

Hi everyone,

I'm currently in the process of implementing a RAP action. This action makes several calls, both through traditional function modules and via RAP objects:

DATA lt_create_materialdocumet_head TYPE TABLE FOR CREATE I_MaterialDocumentTP.
DATA lt_create_materialdocumet_item TYPE TABLE FOR CREATE I_MaterialDocumentTP\_MaterialDocumentItem.
DATA lt_create_matdocitem_sernum    TYPE TABLE FOR CREATE I_MaterialDocumentItemTP\_SerialNumber.

[...]

lt_create_materialdocumet_head = VALUE #(
          ( %cid              = 'CID1'
            GoodsMovementCode = if_goodsmvt=>goodsmvt_code_06
            PostingDate       = sy-datum
            DocumentDate      = sy-datum
            %control          = VALUE #( GoodsMovementCode = cl_abap_behv=>flag_changed
                                         PostingDate       = cl_abap_behv=>flag_changed
                                         DocumentDate      = cl_abap_behv=>flag_changed ) ) ).

      lt_create_materialdocumet_item = VALUE #(
          ( %CID_ref = 'CID1'
            %target  = VALUE #( ( %cid                = 'CID_ITEM1'

A central commit is performed within the RAP save sequence. This results, in this case, in the equipment being set to the Deactivated status before the goods movement could be posted. The latter is no longer possible with an inactive equipment. Afterwards, since the commit to the RAP Object call fails, a rollback is triggered, causing all changes to be lost.

How should multiple action be handled in RAP, that are affected by each other? Is only way to call multiple actions in succession?

Thanks in advance,

Lukas
