During production, if line pairing fails, a document is sent to the Line Pairing Correction activity.

In this activity, a user can select one of the invalid reasons if they cannot process the document for one reason or another. You can control what is displayed in this list by selecting or clearing the Active setting in the Settings > Invoice Processing > Global Settings > Invalid Reasons > Invalid Reason Settings.

Only modify the Active setting for those rules with a Scope of LPR or blank. If the Scope is set to VAL, changing the Active state hides that rule during the Validation activity instead.
