Group Requisitions Generate Purchase Orders

Good morning.

I'm having a problem grouping purchase requisitions that are linked to a purchase agreement.

We have a situation where a legacy system generates requisitions directly in procurement, requisitions arrive all the time and are automatically approved. When the system verifies that the requisition line item has a purchase agreement, a purchase order is automatically generated (ok). The problem is that an order is generated for each requisition.

The agreement is configured to group lines by location.

I need all requisitions to be grouped into a single purchase order. I read some topics here on the forum and didn't identify anything normal with the configuration made.
