Opening & Closing Periods - FI - T.Code: OB52

Dear All,

When I close the existing period and open the new period in Dev Server, after click the Save button it asks Deployment Request No.

If we create new request and transport this deployment to Quality Server to start few testing.

When we do the same operation in Production Server, the system is not asking the Deployment Request number at the time of saving. It is allowing and saving directly. Why?

What is the difference between DEV/QA and PROD server for this kind action?

Could any one guide me.

Thanks in advance

Regards,

SS
