LIBREF, DSN, VAR_NM, VAR_TYPE, VAR_LEN, VAR_LOGIC and ACTIVE are NOT NULL in the table definition, so the requirement is stated once, in the model, instead of being repeated as NOTNULL rules in MPE_VALIDATIONS for each column. VAR_FMT stays nullable: it is optional on a derived variable, and its HARDREGEX already accepts an empty value. The seven NOTNULL rule inserts are removed from the 7.19 migration, and the comment on ACTIVE no longer describes a rule that is not there.

@brief ddl file
|
|
@details Defines the derived (computed) variable configuration table. This
|
|
drives MPE_DERIVED rows in MPE_TABLES, so that the table itself can be
|
|
maintained through the EDIT screen with the usual approve workflow.
|
|
|
|
Derived values are not persisted - the logic is applied at read time, before
|
|
the filter, so that the variables can be filtered on.
