Are you expecting values in the line items to change based on a change in data to the upper form? If so, I assume you are auto-populating that value from the upper form to the detail form. The line items will not change in this scenario, as auto-population happens when you create the line items - it is not dynamic.
Is there a way to force the line items to be re-calculated?
You have to touch each line item to force it. Nothing will do that from the upper form that I can think of.
What exactly are you trying to do?
When you say "touch" what do you mean? I can go to the line item and it doesn't refresh the amount on an approved contingency release.
qty*cost does not equal amount in a few cases and it is throwing numbers off. I would like a way to re-calculate amount so amounts too qty*cost. In some cases, these are auto created on change orders.
