How To Fix AD731 - Foreign key &-& (do not make any more entries on foreign key screen)

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 731

• Message text: Foreign key &-& (do not make any more entries on foreign key screen)

What causes this issue?

It does not make sense to specify a cardinality for a foreign key of
type DYNP. The DYNP dependency factor does not indicate a foreign key
in the conventional sense, but rather a linking of tables consisting
only of the foreign key definition that acts like a check during screen
entry using the mask processor. This applies, for example, to a
foreign key definition for an internal table that does not refer to the
data base.
Apart from the foreign key definition, the actual relationship between
tables consists of the dependency factor, the cardinality, and possibly
the short text and documentation which describe the foreign key in more
detail.
