I like to use IG on a view, which I created on 2 tables (Master/Detail or Order/Order-Details)... with cascade constraints on FK of the Detail Table.
But having changed a column and like to save - the IG is throwing flwg. error saying :
"Ajax call returned server error ORA-20987: APEX - nothing done - ORA-01779: cannot modify a column which maps to a non key-preserved table for ."
What sort of View do I have to use ? Any workaround ? What to consider ?
TIA
