Purchase order deletion error

Hi All,

When i try to deletea PO when the PO status = Open order ( not receive any material against the PO) system throws the following error : The purchase order cannot be deleted because related not posted transactions exist.

What would be an issue ?

Any idea ?

What type of purchase order is it? Is it linked to any other transaction? Have you tried to debug it?

Also, rather critically these days, you have not said the version.
