Hi,

Could you please mention the process you followed. 

But if you have created an invoice and connected to a Work Task then cancelling the invoice and posting it to the relevant task would work.

If the Purchase requisition was initiated from the Work Task then you need to revert back cancelling the invoice, any receipts associated and the Purchase Requisition. and then again create the requisition on the relevant task.

Thanks & Best Regards

Hi, The invoice is also paid.. and the accounting period is closed etc etc… The invoice is correct so why should this be cancelled ? It is only our internal posting that is wrong.  

There must be an easier way to move cost from one work task to another .. in maintenance only.
