Hi,
Scenario:
Parent form: An order form (Order table) with data fields like Order ID and etc. In my Order Table, I have a revenue data field, which is a calculated field based on numbers of items in its subform (OrderDetails table).
Since the profit data field is based on the items of the Order Details, for each time the user add an records in the OrderDetails table, it need to be recalculated. Currently, I used a calculated field in the query of the OrderDetails subform and bind it back to the main form, again it bind it back to the profit data field in the Order table.
With this method, everytime user add a record in the subform, the calculated field in the query will reflect the changes accordingly, but I have difficulty to force the changes in the calculated field to update the profit data field in the Order Table. I most of the events (like On Changes, On Dirty ....) on both parent and subforms, it seems does detect the changes.
Please help ...
