wrong item wbs budget exceeded error during invoice .

Hi Experts,

we have a situation where we get the error -

whereas this wbs doesn't have any line item 3 for any PO, and corresponding PO of this Invoice has only line item 1, please see the screenshot.

I tried the several correction programs with CJEN & CJBN but problem is still there, and available overall budget is 2,436.79 $.

I also checked the tolerence limit which is at 100% with ++, and avail control is active on overall and no Fx is involved too, please help to understand this weird situation.

Thanks,

Vindhesh
