KO88 and KO8G - Reverse not showing all documents

Hi Guru,

One of the user has changed the settlement cost center in the settlement rule on 15th december on an internal order and when we ran our settlements on Dec 31st using transaction KO8G for all internal orders but we we look at order line items in KOB1 all the cost hit the previous cost center and settlement posted to another cost center.

Due to which there is a + and - between the profit centers balances, to adjust this we want to reverse the settlement for this order using KO88 - reverse option but we can see only one document instead of 4 as per KOB1 as on that date.

Could you please let us know how come we can see only one instead of all documents when we try to reverse and i used KO8G to revese but it will not show the documents and amount that we need to reverse.

Could you help in this

Thanks

Kumar
