Problem in Services PO: Urgent

Question

Hi Experts,
I have a big problem with the services PO.
Issue is described as under.
1. One PO was created with Quantity of Services 28. (Price: 1000 INR)
2. The first SES was created for quantity of 4.
3. 2nd SES was created for the quantity 11.
4. Invoice receipt was done for both the 1st and 2nd SES.
5. The 2nd SES of quantity 11 was deleted, therfore all the GR documents and finance documents got reversed.
6. 3rd SES was created with the quantity of 17.
7. GR/IR account maintenance was wrongly done for the 1st SES for the amount of INR 4000.
8. Later when the user has deleted the 1st SES, the quantity has been reversed but the amount has not been reversed.
9. The 4th SES has been created for rest of the quantity 11.
Now the problem is when we look at the Status tab at the header of the PO. It shows
Ordered  = INR 28000
Delivered = INR 32000
This problem is because the when 1st SES was deleted the quantity was reversed and the amount was not. And this is because of GR/IR document wrongly created in MR11. 
Please suggest me the solution, as the business not able to make the payments to the vendor.
Please do revert for any futher clarification.
