The data model looks like this.

(1) is VBAP

(2) is VBEP

(3) is MARA

(4) is MVKE

Now I created an OLAP table with columns from different SAP table.

When I now want to include the SAP field MVGR1 from table MVKE is receive following error message.

How should the formula look like by using e.g. DOMAIN_TABLE or BIND together with PU-Function so that I can display the field MVKE.MVGR1 in the OLAP-Table?
