elements. When the sets are imported from the WBS element's master
data, they are then broken down by the set manager into their individual
values. They can only be created as basic sets belonging to table
fields with the domain PS_POSNR, that is, for example, PRPS-PSPNR.

System Response

How to fix this error?
