Have a strange situation. The user wants to delete some business rules which are not required as the concerned accounts are not using in Consolidation. Thinking that deleting Business rules are suggestive. So is there any work around to comment the business rules???
commenting out a rule is not possible. As Chuan said, if they use accounts that are not used in consolidation you could simply leave the rules as they are. Or you could create a new method based multiplier that doesn't actually do anything and assign this to the rules.
