Change IKEY on DFKKOP Table

[ThamerDoulat]

I need to update the IKEY field on the DFKKOP table, and I can't find FMs to change this value,

I've checked the following FMs and didn't work correctly:

1. FKK_CHANGE_DOC_DB
2. BAPI_CTRACDOCUMENT_CHANGE

Is there any way to change it instead of physical changing (Update the value directly).

AFAIK DFKKOP contains a field IKEY, not BFKKOP?

[raymond_giuseppi]

Did you try to use the EXTENSIONIN parameter of BAPI_CTRACDOCUMENT_CHANGE?

(Add required field in structures BAPI_TE_DFKKOPCH and -X)

thamer_doulat See official SAP documentation + all answers about EXTENSIONIN. It's the same for any BAPI. It's a basic concept of BAPI.

This the code that i used to change the value of IKEY using EXTENSIONIN

FORM UPDATE_DB. 

 SELECT * FROM DFKKOP    
WHERE OPBEL IN @SO_OPBEL AND IKEY <> 'Z1'    
INTO TABLE @DATA(GT_ALV).

  LOOP AT GT_ALV ASSIGNING FIELD-SYMBOL(<FS_ALV>) .

    DATA: LT_PARTNERPOSITIONS TYPE STANDARD TABLE OF BAPIDFKKOPCH,          
                LS_PARTNERPOSITIONS TYPE BAPIDFKKOPCH.

    LS_PARTNERPOSITIONS-LINE_NUMBER = <FS_ALV>-OPUPK.
  APPEND LS_PARTNERPOSITIONS TO LT_PARTNERPOSITIONS.    

DATA: IT_EXTENSIONIN TYPE TABLE OF BAPIPAREX,          
              WA_EXTENSIONIN TYPE BAPIPAREX,         
               WA_RETURN      TYPE BAPIRET2.

DATA: WA_IKEY TYPE BAPI_TE_DFKKOPCH,
WA_IKEYX TYPE BAPI_TE_DFKKOPCHX.

WA_IKEY-LINE_NUMBER = <FS_ALV>-OPUPK.
WA_IKEY-IKEY = 'Z1'.

* Populate the ExtensionIn structure with the additional fields
WA_EXTENSIONIN-STRUCTURE = 'BAPI_TE_DFKKOPCH'.
WA_EXTENSIONIN-VALUEPART1 = WA_IKEY.

APPEND WA_EXTENSIONIN TO IT_EXTENSIONIN.

WA_IKEYX-LINE_NUMBER = <FS_ALV>-OPUPK.
WA_IKEYX-IKEY = 'X'.

* Populate the ExtensionIn structure with the additional fields
WA_EXTENSIONIN-STRUCTURE = 'BAPI_TE_DFKKOPCHX'.
WA_EXTENSIONIN-VALUEPART1 = WA_IKEYX.

* Append the structure to a table
APPEND WA_EXTENSIONIN TO IT_EXTENSIONIN.

CALL FUNCTION 'BAPI_CTRACDOCUMENT_CHANGE'
EXPORTING
DOCUMENTNUMBER = <FS_ALV>-OPBEL
* DOCUMENTHEADER =
* DOCUMENTHEADERX =
IMPORTING
RETURN = WA_RETURN
TABLES
PARTNERPOSITIONS = LT_PARTNERPOSITIONS
* PARTNERPOSITIONSX =
* REPETITIONPOSITIONS =
* REPETITIONPOSITIONSX =
* POSITIONLOCKS = LT_POSITIONLOCKS
EXTENSIONIN = IT_EXTENSIONIN
* POSITIONLOCKS_WITH_COMMENT =
.

IF SY-SUBRC = 0.
* Commit the changes
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
EXPORTING
WAIT = 'X'.
ENDIF.

ENDLOOP.
ENDFORM.



WA_RETURN always get this error :   Different line in change parameter 

Can anyone check the code??

I've created new fields in the structures BAPI_TE_DFKKOPCH and BAPI_TE_DFKKOPCHX as the following:
