How To Fix AD297 - Foreign key &-& (rel. cat. DYNP -> CARD superfluous)

AD297 - Overview

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 297

• Message text: Foreign key &-& (rel. cat. DYNP -> CARD superfluous)

What causes this issue?

It does not make sense to specify a cardinality for relationships
of type DYNP. DYNP does not indicate a relationship in
the conventional sense, but merely a linking of tables that consist
only of the foreign key definition and thus serve as a form of check
during screen entry using the mask processor. This applies, for
example, to a foreign key definition of an internal table that has no
connection with the data base.
Apart from the foreign key definition, the actual relationships between
tables consist of the relationship type, the cardinality, and possibly
the short text and the documentation which describe the relationship in
more detail.
