Sergey: I just got a new report and it seems this is worse situation but it looks is related to the previews problem I posted minutes ago.
When two users are working adding records in Same Application, Different PCs, Different UserId, Different Master RecordId get the list of details records mix up. The detail records that second user entered get associated to the master record of the first user.
Explample:
First UserA starts entering detail records a Master record for invoice #100.
Then UserB starts entering let say 5 detail records a Master record for invoice #101.
When they check the list of detail records entered by the UserB the 5 are shown on the list for Invoice #100 instead of 101.
Please help ASAP thanks
