Hi Acrylon
There are four possibilities:
1) One or more of the accounts in this batch were set up as "consolidated" accounts instead of "detail" accounts. This is not recommended (it is a vestige from the days when disk space was expensive).
2) You consolidated the batch in the subledger prior to retrieving it in GL
3) You consolidated posted transactions - definitely not recommended ever!
4) Your data is corrupt.
While you are at it, make sure that the periods this batch was posted to are not closed.
Regards
Steve
