If Area is divided into County as shown by the following relations:
FIL Country REF Known by FLD Country code CDE FIL Country REF Refers to FIL Area REF FIL Country REF Has FLD Country name TXT
Then to provide a sublisting of the counties for each area, you need a RSQ access path with the following entries:
|
Access Path Entries |
Type |
Key |
|
|---|---|---|---|
|
County code Country code Area code County name |
A A A A |
K3 K1 K2 |
|
|
|
|||
|
|
Note: This access path should be specified so that it has a unique key order.
A Print Counties in Area PRTOBJ function would be based on this access path. Country Code and Area Code would be made restrictor parameters so that only counties for a given area would be printed:
