We reversed one document at that time system is posting to wrong profit center. but in initial document it was posted to right profit center. at the time of revesal only why it was posted to wrong profit center.
and in this reversal segment clearing account is having 2 line items in debit and credit.
why segment clearing account came in to picture at the time of reversal.
Normally the reversal entry also should post in the same profit centre. Why it is being posted to a different profit centre need to be analysed. Please check any substitution rule is active in your system which takes the reversal into a default profit centre.
Since the reversal is going to another profit centre, the segment clearing comes into picture for have balanced entries in both the profit centres as they belong to different segments.
