RAP: Error message in the definition method

[imihailovs]

Hello experts,

Does anybody know if it is possible to stop behavior execution and return the error back to API caller from the FOR DETERMINE method? I am using this method to call a BAPI and change my currently processed entity with a transaction ID returned from the BAPI. However, if the BAPI fails for any reason - I would like to return the error message back to API caller. I have tried populating REPORTED itab, but that doesn't stop the execution and save is eventually executed.

I know that this is possible via FOR VALIDATE methods and with FAILED itab, however I need to use the MODIFY ENTITIES statement (to update currently processed entity) which I cannot use in FOR VALIDATE method (hard error).

Any suggestions

I think I somewhat figured it out.

First, in FOR DETERMINE method I store the message in %msg object of the reported structure, like so:

INSERT VALUE #( orderuuid   = <fs_repair_order>-orderuuid
                %create     = if_abap_behv=>mk-on
                %state_area = 'XYZ'
                %msg        = me->new_message_with_text( severity = CONV #( <fs_response>-type )
                                                         text     = <fs_response>-message ) ) INTO TABLE reported-repairorder.

Then in FOR VALIDATE ON SAVE, I read the entity in question like so:

READ ENTITIES OF zoem_i_repairorder IN LOCAL MODE
    ENTITY repairorder
    ALL FIELDS WITH CORRESPONDING #( keys )
    RESULT DATA(lt_data)
    REPORTED DATA(lt_reported_data).

In this case, lt_reported_data will contain the entity with %msg content that I can analyze and, if any errors are present, populate the "failed" structure.

If anyone knows different (more correct way) of doing it - please let me know.
