ALV

Former Member — Tue, 04 Mar 2008 04:57:31 GMT

I have a parameter screen where i enter the name of any table.

Now i create a dynamic internal table to fetch the data in the table in it.

Till this i have done but now i need to display the dynamic data in ALV output.

So i need to create a ALV with dynamic columns -- I think based on the table i have input.

Kindly help mehow to do it..

Thanks

Hi,

You can use the Function Module DB_GET_TABLE_FIELDS to get the field names of the table. or table for field names is DD03L.

after getting the table field names you can proceed to build the field catalogue.

Hope it helps you.

Kind Regards,
