1.2.7 Reference Field

Specify the name of the field which should be "referred" to. The new field will inherit the following characteristics from the reference field entered:

...

• The reference field must already exist in the repository.

Warnings

• In an RDML partition, if the flag *IMPREFFLDNOPROP is in the system data area DC@OSVEROP, the input and output attributes will not be updated during an import or export. If the reference field is subsequently changed, the changes will be propagated to the fields referencing the reference field. For further information refer to Reference field propagation in import Export and Import settings of the LANSA for i User Guide.
• In an RDMLX partition, the attributes of a field that is defined by a reference field cannot be changed. The *IMPREFFLDNOPROP flag in the system definitions is ignored.

Tips & Techniques

• All LANSA modeling tools that use a data type approach, will use reference fields when building field definitions.
• Make each referred field a 1.2.15 System Field so  so that it won't be deleted.
