BADI ME_PROCESS_REQ_CUST SET_DATA issue in POST

Former Member — Thu, 31 Jan 2013 06:11:51 GMT

Hello All,

I'm trying to change the value of a custom field in ME53N using BADI ME_PROCESS_REQ_CUST during POST. But at 'CALL METHOD im_item->set_data', it throws a runtime error 'Access via 'NULL' object reference not possible.'. Am I missing something in the below code ?

Regards.

Code:

DATA: lt_items TYPE mmpur_requisition_items,

ls_item TYPE mmpur_requisition_item,

ls_header TYPE mereq_header,

* im_item TYPE REF TO if_purchase_requisition_item,

lv_count type i value 1,

lv_item type i value 0.

data: ls_mereq_item type mereq_item,

lv_zzarno type eban-zzarno.

if lv_count = 1.

import lv_zzarno to lv_zzarno from MEMORY id 'ZZARNO'.

lt_items = im_header->get_items( ).

loop at lt_items into ls_item.

ls_mereq_item = ls_item-item->get_data( ).

if ls_mereq_item-zzarno NE lv_zzarno.

ls_mereq_item-zzarno = lv_zzarno.

CALL METHOD im_item->set_data

EXPORTING

im_data = ls_mereq_item.

endif.

endloop.

endif.

Hi,

This error due to ,access the object without actually creating it.

Try to create the object and then use this object or U have not object reference for process.

For one example look at this one,

Change as per ur logic.

Hope it helps.

Thnaks

Well, read again what you have written

ls_mereq_item = ls_item-item->get_data( ).
if ls_mereq_item-zzarno NE lv_zzarno.
    ls_mereq_item-zzarno = lv_zzarno.
   CALL METHOD im_item->set_data " replace im_item with ls_item-item
       EXPORTING
         im_data = ls_mereq_item.

You read data for object ls_item-item and try to update in another unknown object, source copied from another method ?

But POST method seems late in the process, couldn't you perform this in PROCESS_ITEM or CHECK methods ?

Regards,

Raymond
