PO and lease creation for lease contract with budget check case

Summary:

Need solution or workaround for PO and lease creation for lease contract

Content (required):

We are using lease asset (Not lease accounting), procurement and enabled budget check features.

We are using both fixed assets and procurement modules to create lease contract. For fixed assets, we create lease asset to generate asset for depreciation calculation and generate lease invoice to send AP invoice to AP team. For procurement, we create PR then convert to PO. We leave that PO still open and do nothing for the PO. Our client requires to use this PO to send PO document to supplier.
