can REUSE_ALV_FIELDCATALOG_MERGE create the fieldcatlog of Internal_table which is defined as 'type standard table of'

Hello Experts,

I m using REUSE_ALV_FIELDCATALOG_MERGE in my program to get fieldcalog of my intetrnal table which is defined as 'Type Standard table of'.

First i have defined structure of internal table using Types: begin of xyzx / End of Xyz where i use LIKE to define fields.

Problem:

If i pass that internal table / structure name to REUSE_ALV_FIELDCATALOG_MERGE then getting none result wehreas OCCURS (whose structure has defined using LIKE ) gives me FIELDCALOG.

Thanks,

Anoop
