Accounting Document Not Generated: Budget Exceeded

Dear PS Experts,

I am basically an SD Consultant, but learning PS and solving issues for a client who has implemented PS module. I have an issue while cancelling an invoice. Accounting document is not getting generated. It is giving an error message as below.

Item 1003 WBS element S.00000068-00014 budget exceeded

Message no. BP603

Diagnosis

Budget was exceeded by 1,210,838.00 INR in document item 1003 WBS element S.00000068-00014.

Checked with the client, he is telling budget is not exceeded. Kindly let me know if there any setting has been missed out.

Thanks and Regards

Adithya
