Bank Fund Transfer Posting from API

Error: Post the movement from Source Bank Cash to Transfer Account : Wrong sign of Transfer Amount

HI, I had got this error from system monitor while trying to post the bank fund transfer that i had insert using Erp.BO.BankFundTranSvc/CreateBankTranRecords.
i then do posting using Erp.Proc.BankFundPostSvc/SubmitToAgent. can anyone help?

OK i got it fixed. In case anyone in future facing this issue, the amount that i try to insert was -ve and epicor not allow it. after i make it to +ve then it can post success
