MEREQ001 Function Exits 001 and 003 problem in S4 HANA

[Former Member]

For EXIT_SAPLMEREQ_001 the code is:

1. TABLES : ci_ebandb, eban.
2. DATA : lv_mereq_item TYPE mereq_item. "gv_trtyp type AKTVT.
3. CALL METHOD im_req_item->get_activity
4. RECEIVING re_aktvt = gv_trtyp.
5. CASE gv_trtyp.
6. WHEN 'A'.
7. FL_INPUT = SPACE. "Output only
8. WHEN 'V'.
9. FL_INPUT = 'X'. "Input/Output
10. ENDCASE.
11. IF im_req_item IS INITIAL.
12. CLEAR: ci_ebandb.
13. ELSE.
14. lv_mereq_item = im_req_item->get_data( ).
15. MOVE-CORRESPONDING lv_mereq_item TO ci_ebandb.
16. endif.

For EXIT_SAPLMEREQ_003 the code is:

1. DATA : l_mereq_item TYPE mereq_item.
2. IF NOT im_req_item IS INITIAL.
3. l_mereq_item = im_req_item->get_data( ).
4. IF ( ci_ebandb-zreason NE l_mereq_item-zreason )
5. MOVE-CORRESPONDING ci_ebandb TO l_mereq_item .
6. CALL METHOD im_req_item->set_data( l_mereq_item ).
7. ex_changed = 'X'.
8. ENDIF.
9. ENDIF.
10. ENDIF.

I have created two structures CI_EBANDB and CI_EBANDBX with same custom fields. But for same fields in CI_EBANDBX I created with CHAR1 datatype.

But no data is updating in EBAN table from 003. <removed by moderator>.
