Hi
I am facing a problem using this FM. I have an Internal Table called OUT_TAB[] which is to be output using ALV List. Now to construct the FieldCatalog i used this FM and passed the name of the itab in the i_internal_tabname parameter. But it gives me a dump. So i created a structure called STR_NAME in ABAP Dictionary and referenced it in the FM. Now it is working fine. But i still dont want to create a strcuture unnecessarily. Can anyone help.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
i_internal_tabname = OUT_TAB
i_structure_name = 'STR_NAME'
I_CLIENT_NEVER_DISPLAY = 'X'
I_BYPASSING_BUFFER =
I_BUFFER_ACTIVE =
