Please mention the problem clearly. Is it that you want to change a field that references another field ? Where is the problem exactly ? |

Referential Integrity... that' s the buzzword
You simply cannot do it, it is not a fileaid issue...
it' s a table/application design constraint !! |

| Add the needed row to the parent table first or drop the referential constraint. |

Hello,
You might also talk with your dba(s) to make sure you understand the "rules" concerning these tables. |
