field catalogue update problem

[Former Member]

Dear Friends;

I have a problem with field catalog update of ALV grid(ABAP Objects not just fm use). I have designed an initial screen for selections and there are two pushbuttons here. According to the pushbutton selection the field catalogue values change, ie. some fields are hidden etc. After the first selection this works but if i exit the second screen and go to the selection screen to change my selection the fieldcatalogue is not updated accordingly altough i call the relevant fm. i fill in fieldcat with fm LVC_FIELDCATALOG_MERGE.

Can someone suggest a solution pls?

Thx
