Hi,
there is no way you can automatically create the PR of different orders. the reason being, the PRs are created and updated when you create/update the order. In case you have multiple orders, it is not possible to judge what orders have to grouped together to form a PR
You may have 100 orders, however, how will the system decide what orders you want under a single PR. And if you maintain some criteria for this grouping, what will happen if new orders get created just before PR is released. Or if the PR is released and new order gets created, the PR will get modified with additional lines in it (due to new order), the release strategy will again be reset.
This is logically also not possible to group the orders in one PR. Please explain the clients that even in general business (outside SAP) this solution is not feasible.
