We create Quotes and POs in a table named "Files" which uses the table "Files Detail" in a portal for the line items. Simple right, been working great for over 2 years. About 2 weeks ago the line items stopped updating dynamically when a change is made. If you change the quantity or price on a line in the portal you have to click on the "Amount" (QuantityXPrice) field to get the new extended price. Also, this does not update the Total field which calculates Sum(Amount) from the entire portal. You have to go away from the record to get the Total to show up correctly. I am not exactly sure when this started, I have a copy of the file I made almost 4 weeks ago that does not have this problem so it started since then.
To get something simple out of the way; it is not an indexing problem, nothing is being indexed in the Details table except the unique ID field.
At a loss,
