Apply entry in Z-table in macro

Hello,

I have following issue:

I want to apply an entry in a Z-table within a macro.

In detail: I have a key figue in a planning book. The value in each bucket of the planning book of the key figure should be mulitplied with a value which can be determined from a Z-table.

Does somebody know how to realize this "connection" between a macro and the entry in a Z-table?

Please reply!

Thanks and kind regards

Heinz
