When releasing a Journal Voucher, why is the Project on an AP Prepayment overridden to ‘X – Non-Project’ ?

HI ​@kimhung 

Project code X is one of the ways by which Acumatica tries to keep the data consistent. While entering any document, you can directly connect it with any project that is configured in your system. But if the document is independent, then Acumatica automatically puts that document under X, which basically means that it is a “Non-project document.

Here’s an example for project related document

Is your Journal voucher related to any project? If yes, then the source document needs to be edited by entering the correct project details. If not, then it automatically gets assigned as an X-non project document.

Here’s an example of “X-non-project” related document

Hope this helps.
