Holding and posting document through F-48 not clearing down payment request

Hello, All

When we are posting a down payment in F-48 by referring the down payment request, the system automatically clears the down payment request and post the down payment to the vendor. But when we hold the down payment transaction first (Still referring the down payment request document) and later post it through FB11, the system is not clearing the down payment request document automatically. This poses a problem because since it is not clearing the down payment request, a user can mistakenly post another down payment for that same vendor referring the same request that it refers previously.The only reason we are holding the document first is for two-way process of posting, one user to hold and the other to post the document.

How do I solve this problem?, Advice me.

Thanks

Yishak.
