Hi,
I have created one form with two block.
Block-1 : Based on View
Block-2 : Based on table

There is is relationship between Block-1 and Block-2.
Block-1 is populating from LOV.
I just need to insert /update record Block-2 based on data from Block-1
So Block-1 I have made read only at runtime (Inser/update all properties are false).

Now when I insert record in Block-2 based on record from block-1, and getting below error.
"ORA-01779: cannot modify a column which maps to a non key-preserved table"

It is not allowing to insert record.

Please help me.

You've got some code that's modifying block one.

You can only get that error from trying to do DML on views.

When you say you're populating block1 from an LOV what exactly do you mean?

That really doesn't answer my question.

Are you using forms default query behaviour or are you manually populating the block from a cursor/procedure or something else?
