Open orders amount at credit check not matching

Hi

The issue is  "Enquire for Sold to level Open Sales orders as i understand orders Next status less than 999 and last status not equivalane to 980  select any row and go to row exit at sales order application ,select customer and click on credit check ,  Where there is Open order Amount  say some figure $100.  Take form exit to find open orders, calculate the amount and FOUND THAT AMOUNT IS NOT MATCHING FOR SOME CUSTOMERS.

Hence ran Repost program R42995 with Optipn of open order amount update in processing options. But still difference existing. though Assume future orders or back orders if showing under Open orders in credit check application, it should Sync the amounts.
