>>I'm facing the following rather strange problem. I have a form with agrid and set of command buttons for entering data for a many to manyrelationship. When the forms data session is set to default data sessionit works fine but if I set it to private data session after sometime I get the following error - Record in Use by another User!This is really driving me nuts.Thanks for all the helpSonali >Hi Sonali, >As Steven pointed out some sets scope to the current data session. "set exclusive" is one of them. You may need to set it for private data session too. >Cetin I don't want to set exclusive on as I am allowing the user to open up other forms and this would then restrict the user's options. Further the long term plans are for a multiuser system Thanks Sonali
