well, I have had this isuue long before but, thought of sharing the issue.
I have a key column setup not as autonumber but as a "number"
like this 2002xxx, where xxx is the number that changes when user inputs new set of data.
Problem arises when 2 users simultaneously enter SAME 2002xxx number adding new data. in this case
I receive two rows of data with the same ID
for example
2002123 John Doe Manager Ok
2002123 Jane Doe subordinate Ok
did any one had same problem?
