Suspended Receipt Batch

Hi All

I have encountered an issue with a client that I have never seen before.   On attempting to release a return receipt batch in purchasing the user encountered a system message 10232 - Assertion Failure error message.

On checking the event log created, the log file indicates  - System Message 17324: Warning - in batch 494166 transaction amount exceeds cost  layer amount.

The inventory item is using FIFO valuation method so their are cost layers due to the method.  I am not sure how to go about to correct this issue.

Any assistance in this issue will be appreciated.

Thanks

Regards
