Hello
I have created two applications and they are sharing the same DB schema at apex.oraclecorp.com.
One is Purchase Order app, when user enter "Purchase Request Number" and select "ERT HW/Item ID: HW/Item Name"
and click "apply change" in the tabular form, the other app in 3rd screen shot, will automatically update the data with selected item ID with the "purchase request number".
I have done this by the following code in first screenshot.
I would like to know how to create a delete process for this?
That mean when I delete the one of item in purchase order app, the other application can update the item with that purchase request number (PRM) as null?
How to specify the item I checked to delete ?
Thank you!
Alice
