SAPScript and print program

Hi,

I have 2 sap clients, client 001 and 002. Client 001 has the sapscript zsapscript001 and print program zprint001 for PO forms. Client 002 has zsapscript002 and print program zprint002.

The requestor wants the PO forms in client 002 to be the same as the PO forms in client 001 so I made a copy of zsapscript001 and print program zprint001 into client 002, I named them zsapcript001copy and zprint001copy.

After this, I made the changes in transaction SPRO in client 002 to set the assigned form and print program for POs. I replaced zsapscript002 with zsapcript001copy and print program zprint002 with zprint001copy.

When I try to 'print preview' the PO form, I am getting the error: "Error in OPEN_FORM for document <PO number>". What may be the problem? Am I missing other settings? Thanks.
