(I am on > a stand-alone computer.) Can you duplicate this interactively? Is this an inventory buffer or invlines buffer? Is the seek used to verify/fetch a description, or is the inventory table modified at the same time? With optimistic table buffering indexes aren't updated until tableupdate() succeeds. > B.

How is it opened? Is it opened in the Data Environment of the oInvoice class? VFP seems to "inherit" usage status from previous openings of a table. (There was a recent FP Advisor or FoxTalk tip/article on this.) Are you sure the verifiction is being done on the oInvoice copy of Inventory? >That works fine; > however, I have to move the pointer in the copy of Inventory that the form > has open. How can I accomplish that without flushing the buffers???? Why do you have to move it? Have you thought of doing your manipulation of the Inventory table in an update trigger on InvLines? These are all shots in the dark, but I hope they help.
