You can check below tables
Erp.ACTType - Stores the gl transactions like AR Invoice and AP Invoice
Erp.ACTRevision - Stores the revisions, you could have Blocked/Draft and 1 Active Revision per ACTType
Erp.BookingRule - Stores the actual posting rules per revision
RuleUID must match the actual booking rule that generated that TranGLC record, for example in my previous post the rule is named “Post Extended Price Amount(Regular Invoice, Part)”
