Every PO go into B1 -Budget hold

Hello,

We are in process of implanting of Budget module on JDE 9.11 Platform , we have found some questions regarding the same....please guide us

1.We have set budget by Business unit , when we prepare PO for that business unit each PO goes into to budget hold ,even though it's within budget limit , is this system functionality?

2. When user go & modify the PO automatically budget hold is removed , how this can be possible?

Thanks,
