Invoice blocked for payment for Limit PO with GR

Dear SRM Guru,

Here is a real case scenario where invoices are blocked for payment due to price tolerance for Limit PO with GR confirmation. 

         Step 1)  I created a limit PO for $100,000

         Step 2) Performed Goods Receipt confirmation for $50,000

         Step 3) Posted an invoice for $100,000.  Since this invoice blocked for payment due to price tolerance, we performed 2nd GR for $50,000

         Step 4)  Performed 2nd Goods Receipt confirmation for $50,000.  This GR confirmation create a new entry sheet and does not release the block for                       the above invoice from step 2

We had to reverse the original invoice posted from step 2. Once the invoice is fully reversed, it got re-posted against the two entry sheets from GR 1 and GR2.  This process seems to be very time consuming and we are having issues with electronic invoicing that are related to Limit PO with GR.

It is greatly appreciated if anyone can provide some help or their experiences with posting invoices against Limit PO with GR.

Thank you,
