PR to PO (with different buying legal entity than current legal entity) in AX 2012

Hi,

Can we restrict to create PO in the same legal entity against PR irrespective of buying legal entity selected on PR?

Here is details, we have two legal entities T1 and T2 . We used to create PR’s only in T1 but sometimes we will select buying legal entity in PR as T2 .In this case when we converting PR to PO, purchase order is creating in T2 because we selected T2 during creation of PR.But we don’t want PO in T2 all PO’s should be created in T1.

Is there any way to create PO from PR in the same legal entity irrespective of buying legal entity in PR?

Thanks.
