Hi,
Required field might be hidden by SAP.
thru small abap code we can enable required field for selection.
Lets check table - ROOSFIELD and see your data source and fields.
field CCODE - Coulmn SELECTION - A(hidden by SAP). If yes then we can change that selection property A to P/X.
use below sample code and do the syntax check.
You need to write below logic at source side SE38.
do it dev system and later do test load. After that you can move your program to further servers.
Sample Code.
REPORT ZSELECTION.
Tables: ROOSFIELD.
SELECT SINGLE * FROM ROOSFIELD WHERE OLTPSOURCE = '0CO_OM_OPA_6' AND
OBJVERS = 'A' AND FIELD ='CCODE'.
IF SY-SUBRC = 0.
ROOSFIELD-SELECTION ='X'.
MODIFY ROOSFIELD.
ENDIF.
Execute above program once and later check data source at RSA6. it mgith be enabled for selection.
Thanks
