Critical :MIRO TRANSACTION-POP UP SELECTION FOR MULTIPLE VENDOR SELECTION

Question

Hi experts ,
I have a requirement in my project in which AP ( accounts payable ) requires pop up selection box in MIRO when there are multiple remit to address exist for the same vendor.Currently AP does not have the ability to see  when mulitple remit accounts exist for a vendor.   This is causing payment to be sent to the wrong place.so the requirement is 1.Modify the MIRO transaction to determine if a multiple remit-to vendor scenario exists and issue an info message to the user so that he/she can perform a vendor search.
Modify MIRO to Issue Info Message for Multiple Remit-to Scenario
If possible, find an appropriate BAdi or user exit where an info message can be issued.  The message must be issued after entry of the purchase order number.
Determination of a multiple remit-to case is as follows:
-     User in transaction MIRO enters a value in the purchase order number field and presses enter or other function key
-     In exit code:
o     the vendor number is determined from the purchase order entered
o     the vendor master is then searched and the following vendor records are returned as matches:
     ADBR remit-to vendors defined as partners to the purchase order vendor number
     Vendor records with the same tax ID number as the purchase order vendor number
     ADVN vendor records with the same value in LFA1-ZZMCOD2 in the first 12 characters only
     Include the vendor number defined to the purchase order number entered
o     If the search returns more than one vendor record, then issue the info message u201CMultiple remit-to vendors may exist.  Please validate vendor on PO with vendor on the invoice.u201D
can anybody provide any inputs in this.

I have wondered about this for a while. I was trying something tonight and it seemed to do what you need. I suggest you save your document before trying it.
Select one of your popups.
Copy Style
Select all the popups
Paste Style
With all selected, go to the Inspector and add another item to the list.
All popups should now have the new item. The selected values should not have changed. Copy/paste style is required to make this work.
Please let me know if this works for you. I've tried it a few times and it seems to do the trick.
