Q: How to identify reason for reserve/unreserve failure

Hi Guru's

What is the best way to establish the reason for why a purchase order is failing funds reservation or why it is failing the unreserve step. Many users are facing this issue and we are not sure how to track the correct reason or how to fix it.

For example: When reserving a purchase order or release on ppo it could fail and then in reviewing the results of budgetary control it produces a 'supposed reason' but in understanding this reason is where users are getting stuck and how to fix the issue.

Any guidance or help would be appreciated.
