BAPI_REQUIREMENTS_CHANGE: Data deleted

[Former Member]

Hi

Any existing data in other weeks gets deleted. Why?

Week 1 to 5 exists.

I want to change week 2 and 5 but week 1 , 3 and 4 are overwritten/deleted.

    

TYPES : BEGIN OF tp_data,
          matnr LIKE bapisitemr-material,
          plant  Like BAPISITEMR-plant,
          week LIKE scal-week,
          qty(30),
        END OF tp_data

DATA : t_table TYPE STANDARD TABLE OF tp_data WITH HEADER LINE.

LOOP AT t_table.

 REFRESH i_requirements_schedule_in.

  perform populate_requirements_schedule.

CALL FUNCTION 'BAPI_REQUIREMENTS_CHANGE'
            EXPORTING
              material                = t_table-material

              return                         = return.

ENDLOOP.

Hi Giovanni,

BAPI_REQUIREMENTS_CHANGE is used for changing the Planned Independent Requirements (PIR). However it does this by deleting the old data first

corresponding to the Mateiral and Plant. This the reason why data for week 1 , 3, 4 and overwritten / deleted. However this bapi cannot be used to delete an independent

requirement only.

Thanks

Vijay
