Nope. You'll need a 3rd party application to do that.

Why would you export a PO from one company into a PO of another company? Shouldn't you be importing the exported PO as a Sales Order in the second company? BV CAN do that.

How does that work?  I can export the PO from File >> Export >> Standard but can't figure out how to import it as a SO.

Does anyone know how to import a PO (that was exported from a BV company) into a second BV company as a SO?  According to BVROB, "BV CAN do that".  How?  Is this in the kb somewhere? Hello?

Try the help menu in BV and look for Sales Order Import for details into specifics. The actual process is in the FILE/IMPORT module.

I already know how to import a Sales Order - that's not what I'm trying to do.  The Order File Import process will only import exported Sales Orders (created using the Order File Export process, which cannot export PO's). I want to import an exported PO as a SO, exactly like BVROB advised:

"Shouldn't you be importing the exported PO as a Sales Order in the second company? BV CAN do that."

Here's the scenario (the "why" is unimportant - it's all hypothetical):  There are 2 BV companies set up - COMPANY A (customer) and COMPANY B (vendor).  COMPANY A wants to purchase something from COMPANY B so they create a Purchase Order and export it.  I then want to import that PO into COMPANY B as a Sales Order.  After a week of trying, I don't think it can be done.  The only way to export a PO is using the Standard export process, which creates 2 CSV text files (one for header and one for detail info) or 1 Excel file.  There is no way to then import that PO into a second company as SO.

after reading some help info it appears you may be able to create a purchase order from a sales order in your second company then import the purchase order. Cannot see anyway other than third party to do it the way you want

No you CANNOT do this within the BV user interface. Then Order Import function in BV relies on a very specific and rather complex file format for the import. It was designed to import Orders exported by the Order Export function (to be used by, for example, salespeople on the road). The fields in Sales Order are radically different from PO.

Custom programming will be necessary to accomplish this. It is certainly do-able within that context, however.
