There are old transactions on our audit trail which back date to 2008 / 2009 which for some reason were never CIS reconciled when the purchase payment was made & then the return was submitted using the CIS Module.

This is clearly an error in the software at the time as the nominal codes & tax deducted was all done through Sage but for some reason, it was never reconciled & therefore can never be deleted / cleared from the audit trail.

It must be easy to put a feature in place within the software so that any transactions which are older than 7years (where it's no longer a requirement for HMRC) to just clear those transactions anyway regardless of whether they have been reconciled. 

The error is clearly a bug in the CIS Module at the time as we have been using it since it was first released over a decade ago.

Seems silly that the only way to remove these transactions from the audit trail is to completely rebuild the data which is an un-necessary task when we don't have that many splits anyway.
