I have prepared Purchase Order with Revenue standard Purchase Order type.
Also prepared Down payment request against that Purchase Order and paid cheque to vedor also.
After that came to know that purchse order which prepared and payment made was wrong . it should be of Capital type
of purchase Order. 
Now how i can change Order as i have made DPR and paid to vendor also. I cannot take cheque back from Vendor.
IEven cannot cancelled Payment docuemnt as already paid to vendor and vendor has deposited that cheque in Bank.
can i change Purchase Order reference in DPR and Payment document. if possible then i will prepared new Purchase Order and  will  change Purchase Order ref. in DPR and Payment document
Is ther any other way for my problem.

Hi,
Its not possible to change the PO numberr from Down Payment request even by using Document Change Line Item Options. Only possibility for you now to manually adjust this down payment using F-54 against a new line item in PO. So you should create a new line item and post Goods Issue and Invoice. Then after invoice processing you can clear the down payment against this invoice document.
Since vendor is same and PO is also same so you should not be having any problem.
