Important Observations
- Your table OAM needs to be recompiled once access routes are added.
- The type of PJC that can be created is based on the definition of the access route. If the relationship is one to one, only a lookup can be created. If the relationship is one to many, calculation type PJFs can be added.
- PJCs are listed on the Table Columns tab and can be edited from this tab but they cannot be added. You need to add a PJC by first selecting an access route on which the PJC will be based.
- In addition to defining PJCs, access routes are used in LANSA templates to show related tables and in LANSA Client to show linked or joined tables.
