This is from your initial question:
"But our requirement is it should it to same GL account of GBB as Debit and Credit when they are using 555 ..."
Some replies later you posted a screenshot and wrote:
"please refer the below screen shot it has been posted to same GL account of BSX & GBB.
we want this desired accounting entry when we use movt type 555"
then I asked you how you got the values in the screenshot and you answered: "This is transaction of MB1A with Movt type 555"
So where is the reason for this discussion if you have already everything in place?
Or Was your last answer wrong?
