Symbolic structure notation: I want to work with symbolic structure notation based on SAP data dictionary, e.g.

Set V[test1] "&V[plantdata](BAPI_MARC_GA-PUR_GROUP)"

But there is an error messaage stating that PUR-GROUP is not found. I checked the names and the dictionary structure and I'm sure that the field is part of the structure. What could be the reason for this error?

The RFC user probably doesn't possess the necessary SAP user authorizations. It needs

S_RFC: RFC_TYPE=FUGR, RFC_NAME=SIFD, ACTVT=16

S_DEVELOP: DEVCLASS=*,OBJTYPE=TABL,OBJNAME=*,ACTVT=03

Please observe that unless you work with RfcCurrentClient in GuiXT Profile, the RFC connection for the Data Dictionary is executed in client 000.
