Hi Tamil,

In the fieldcatalog keep only the fields you want to display, But you can pass the

output internal table fully.

Ex.

You output internal table have

MATNR

MATKX

DESCR

but you want to display only MATNR and MATKX.

then in fieldcatalog keep only fields MATNR and MATKX

This way you can decide which fields to be displayed at runtime
