Error when adding an Invoice

Dear all,

I get the error below whenever i add an A/R Invoice copied from a Sales Order.

[Microsoft][SQL Server Native Client 10.0][SQL Server]Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. (CINF)

My G/l account are set per item group. I have no Transaction notifications on my database, neither do i have formatted searches.

I run a query on the CINF table of the database, and below is what i got.
