• Message text: Assignment is to first table of join

What causes this issue?

In a functional area that works with a table join, you want to link an
additional table or to define an additional field.
Although a table join contains several tables, a sequence of records
with the same structure is edited, i.e. there is no hierarhical
relationship between the individual tables. A functional area with a
table join is therefore analogous to a functional area where a table is
read directly.
All the tables in the join are filled with values at the same time (the
timepoint of record processing). The table in the join to which the
additional table or additional field is assigned is therefore
irrelevant. For technical reasons, the first table is always selected.
Note that in a table join you can always access all the fields of the
tables of the join when you formulate a WHERE condition or coding
paths.
