CCAP_ECN_MAINTAIN use

[Former Member]

Hi.
I have a program that will automatically change or create material BOM using BAPI. But when you create or change there is no possibility to convey the description (AEOI-OITXT) in the room changes (AEOI-AENNR), it Changes Master. This description is very important and is used in other reports.
Batch input using transaction CC02 is not possible.
Looking for FM or BAPI and found CCAP_ECN_MAINTAIN.
Before you start cause CCAP_ECN_HEADER_READ to get the output of HEADER and submit it to the entrance CCAP_ECN_MAINTAIN, as well in the HEADER add two fields INDATE_RULE = OUTDATE_RULE and VALID_FROM = VALID_FROM.

CALL FUNCTION 'CCAP_ECN_HEADER_READ' 
EXPORTING 
CHANGE_NO  = '40000_240317' 
IMPORTING CHANGE_HEADER  = Z_AENR_API02 

MOVE-CORRESPONDING Z_AENR_API02 TO Z_CHANGE_HEADER. 
Z_CHANGE_HEADER-INDATE_RULE  = Z_CHANGE_HEADER-VALID_FROM. 
Z_CHANGE_HEADER-OUTDATE_RULE = Z_CHANGE_HEADER-VALID_FROM.

Also, the input is OBJECT-BOM, with the fields ACTIVE = X and OBJ_REQU = X.

DATA OBJETCT_BOM TYPE AENV_API01. 
OBJETCT_BOM-ACTIVE  = 'X'. 
OBJETCT_BOM-OBJ_REQU  = 'X'.

After choosing data changes from the table AEOI, and to transfer to CCAP_ECN_MAINTAIN.

SELECT * FROM AEOI INTO CORRESPONDING FIELDS OF TABLE LT_AEOI 
WHERE AENNR EQ '40000_240317' AND AETYP EQ '02'. 

IF SY-SUBRC IS INITIAL. 
LOOP AT LT_AEOI ASSIGNING <AEOI>. 
APPEND INITIAL LINE TO Z_OBJMGREC ASSIGNING <MGREC>. 
<MGREC>-CHG_OBJTYP  = 4. 
<MGREC>-BOM_CAT  = '1'. 
<MGREC>-BOM_STD_OBJECT = '251654321040000000'. 
<MGREC>-BOM_USAGE  = '1'. 
<MGREC>-DESCR_OBJ  = 'Text 111'. 
<MGREC>-PLANT  = '1000'. 
ENDLOOP. 
ENDIF.

And actually cause CCAP_ECN_MAINTAIN.

CALL FUNCTION 'CCAP_ECN_MAINTAIN' 
EXPORTING 
CHANGE_HEADER  = Z_CHANGE_HEADER 
OBJECT_BOM = OBJETCT_BOM 
TABLES 
OBJMGREC  = Z_OBJMGREC

The result is an error:

" processing of Change Number XXXXX cancelled ".
