selection in layout BPS

Hi all,

In BW-BPS I create a layout with Key figures in Data Columns and I need to restrict key figure to some characteristic value.

For example I put in data columns 0QUANTITY and 0SALESORG. I need to restrict 0QUANTITY with value 01 and 02 of 0SALESORG.

For do it I create a variable related of 0SALESORG with replacement type fixed value 01 and 02 and in second screen of the layout builder I add this variable for restrict 0QUANTITY but I receive the following error message:

Variable is not a single value. It cannot be used

Message no. UPP_LB075

I work in BW3.5.

How can I do please?

Thanks a lot

Gianmarco
