Issue showing message in custom action extension of Manage Sales Order v2

[bwal]

Hello,

I'm working on adding a custom action to the application Manage Sales Order V2. The behavior is for the SalesOrderItem entity. I've extended the behavior C_SALESORDERMANAGE, added my action for the entity SalesOrderItem and implemented it. I've added a Metadata extension to show the button above the Items table in a Sales Order object page. The action is now working as expected, I'm having an issue with showing the  standard warning message "Reorder point for item <Item_number> has been exceeded: <X> PC" which shows up the requested amount is too high (it's part of the "normal" application).

I have done the update operation like this:

      LOOP AT read_entity ASSIGNING FIELD-SYMBOL(<ls_read>).
        MODIFY ENTITIES OF c_salesordermanage IN LOCAL MODE
            ENTITY SalesOrderItem
            UPDATE
            FIELDS ( RequestedQuantity RequestedQuantityUnit )
            WITH VALUE #( ( %key = <ls_key>-%key
                                     RequestedQuantity = <ls_key>-%param-NewQuantity
                                     RequestedQuantityUnit = <ls_key>-%param-NewQuantityUnit ) )
           FAILED DATA(modify_failed)
           REPORTED DATA(modify_reported)
           MAPPED DATA(modify_mapped).
ENDLOOP.

The Failed, Reported and Mapped tables are coming back empty even though the entry I've made should bring up the message (which is related to the parent SalesOrder). If I do a read like this after the modify:

      READ ENTITIES OF c_salesordermanage IN LOCAL MODE
        ENTITY SalesOrder
          ALL FIELDS WITH VALUE #( ( %tky = <ls_key>-%tky  ) )
          RESULT DATA(read_after_update)
          FAILED DATA(failed_read_after_update)
          REPORTED data(reported_after_update).

I get one row in the SALESORDER table of the reported_after_update table. Shouldn't this message also appear in the reported table of the MODIFY operation? The row in read_after_update has the expected SALESORDER, the expected message object (%MSG) the %STATE_AREA is SALESORDER. I've copied the content of reported_after_update to the derived Reported table of the method.

If I empty the %state field of the Reported table, the message comes up as a pop up in the middle of the screen instead of the expected area and log.

If I leave the state as it comes back from the table I get a short dump with Exception CX_ABAP_BEHV_RUNTIME_ERROR and the message "Invalid STATE message (%STATE_AREA filled) for entity C_SALESORDRITEMMANAGE".

Does anyone have any idea how to show the warning message in the correct place?

A bit about what I tried:

I did some debugging and I found that in CL_ABAP_BEHV_CTRL the following condition is done:

  if <reported> is not initial.
    if handler_kind = 'M' and handler->meth <> 0 and line_exists( <callparams>[ op = 'A' ] ).
      " was this an implementation for a projection action?
      job->load_root_infos( ).
      if job->root_infos[ root = stdpar-root ]-itype = cl_abap_behv_load=>c_impltype_PROJECTION.
        handler_kind = '%'.  " ... then reject STATE messages (dump)
      endif.
    endif.

When I fill the %state message in my reported table I get handler kind 'M' and The job->root_infos table has one entry which (correctly) shows that the root is C_SALESORDERMANAGE and the type of the caller is a projection (also correct). If I understand it correctly this condition forbids raising a message with a state value if it comes form a projection, is there a reason for that?

Just to try it out I also implemented the method (under a different name) in an extension to r_salesordertp and a "use action..." in the extension for C_SALESORDERMANAGE. In that case the message is not shown but there's no dump.

All the best,

Ben
