Error in Express Deposit page while applying partial payment to Item

Hello

We are on PeopleSoft 9.2. While applying payment to an invoice in Express Deposit page, system throws below error message-

"Item XXXX, YYYYYY, CCCCC has not successfully passed budget checking (6040, 768)

This item is not yet available for payment processing. If you have changed the amount vale for this item, you must delete the item from the worksheet in order to proceed."

The invoice is created by adding prepaid lines in Contracts. Processes run after that are as follows- CA_BI_INTFC, BIIF0001, BIIVC000, BI_IVCEXT, BIPTUNIV, BICURCNV, BIPRELD, BILDGL01, FS_BP, BILDAR01 etc. Once the invoice is in AR, user tried creating payment via Express Deposit page. The above error is received.
