How to create ALV fieldcatalog dynamically.

Hallo guys,

I need to create ALV report where fieldcatalog depends on content of data dictionary table.

In table ZXY I have column ZCOL with values VAL1, VAL2, VAL3... . This values I need to get

into columns of ALV. Is there any way how to do it?

According to this layout I have to get also data into internal table and display them in ALV.

Thanks.
