I am working on a managed Scenario where I have single root entity. Based on certain key value ( Purch Order ) I am supposed to update other field values while in the object page. I have tried to implement
determination updPOdata on modify { create; update; field suppl, refval, curr, collNo; }
METHOD updPOdata.
" Read all relevant PO data.
READ ENTITIES OF ZBILLDATA IN LOCAL MODE
ENTITY _billD
ALL FIELDS
WITH CORRESPONDING #( keys )
RESULT DATA(lt_podata).
LOOP AT lt_podata ASSIGNING FIELD-SYMBOL(<fs_po>).
* Update
<fs_po>-refval = 10. " Hardcoded value for debug <Remove>
<fs_po>-curr = 'USD'
ENDIF.
ENDLOOP.
MODIFY ENTITIES OF ZBILLDATA IN LOCAL MODE
ENTITY _billD
UPDATE FIELDS ( refval curr )
WITH CORRESPONDING #( lt_podata )
REPORTED DATA(lt_reported)
FAILED DATA(ls_failed)
MAPPED DATA(ls_mapped).
ENDMETHOD.
This did not works so I tried other things.
I have also tried the above using Create Operation instead of Update. For create operation the values get updated but I get duplication of values. Also the value does not get immediately reflected back in the object page for updated fields ( Like screen table in module pool program) instead you have to go back to the list page and see the updated values.
I have also tried using calculation class but in this case data only gets displayed and not persist in the table.
Please suggest a suitable workaround for :
1. Updating other fields from key fields in object page.
2. Post create action the screen should show the updated values in object page itself.
