Can i link a requisition for blanket Release, for a global blanket agreement.

To establish a blanket agreement, i raise a requisition, which hold the budgeted amount. later the Blanket AGREEMENT is created, requisition is returned and a releases is created to hold the fund.

Now the issue is, when the release is amended/unreserved, the budged amount increases the fund availability, and this particular previously planned and approved amount is utilized for another payment, which is causing thee issue.

Is there any way i can link the initial requisition raised, to release? so that when i amend/ unreserve the budget amount stays as commitment in the encumbrance ?

Regards,

Chaks
