MIRO should not allow to do posting

[vigneshs1]

Hello SAP consultants,

Hope you are all doing good,

Scenario,

Service PO has been created for 10 Qty and Service entry note done for 10 Qty & MIRO has been done for the same.

Here comes my question, once MIRO has been done for the whole PO 10 Qty, If i go to the MIRO page again and entering the PO number for adoption, system should throw an error which means there should be an validation.

How to configure this part?

I would really appreciate if anyone guide me through it.

Technically, You do not have to do this --here are valid reasons 

1. SAP automatically does 3 way match -you mentioned PO Qty=GR Qty= IR Qty and amounts --then 3 match is good -- invoice will not be blocked -- if there PO amount difference or Qty difference -- depends on your tolerances limits configuration -invoice will be automatically blocked 

2. Normally if vendor can send credit or debit memo based-- you should let that happen--not put any hard blocks what you are seeking 

3. if the vendor is sending you a duplicate invoice --then you should activate the duplicate check configuration --so that system can let you post if it duplicate invoice check is activated in SAP

I do not see reasons why you want to put a blocker when the system has enough ways to handle these situations. It may lead to more issues than a solution.
