Adjustment tolerances being ignored

Summary

I can't adjust a transaction in transaction matching when a variance is present, despite setting manual match tolerance to +/- 100%

Hi All,

I am trying to adjust a single transaction in transaction matching. I have set my manual match tolerance to +/- 100%, but when the value of the transaction is over £100, it doesn't allow me to adjust it, giving a 'Variance of adjustment is not within tolerance limit' error. Below £100 it allows me to do so.

Any ideas on why this might be the case?

Thanks,

James
