Delete source_package

Dear Experts

I am trying to delete from source_package where zdatefrom <> datefrom.

The transformation syntax checker says E: Field "datefrom" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement.

I checked tys_SC_1 the field names are shown there as datefrom for infoobject 0datefrom.

Please help.

regards

Pascal
