Help Document

Diagnosis

You attempted to link an additional table or define an additional field in an InfoSet which uses a table join.
Although a table join contains several tables, a sequence of records with the same structure is processed, i.e. there are no hierarchical relationships between the individual tables. Therefore, an InfoSet which uses a table join should be regarded as the same as an InfoSet which directly reads a table.
All tables in the join are filled with values at the same time (when a record is processed). Consequently, it is irrelevant to which table in the join you assign the additional table or the additional field. For technical reasons, the first table is always chosen.
Note that, in the case of a table join when formulating the WHERE condition or sections of code, you can always access all fields of all tables involved in the join.
