Changing data load mappings process

Summary

What to do with already loaded data when changing data load mapping in transaction matching

Content

Hey There

So we have a requirement where, we want to add 4 ignore rules to the reconciliation id on both sources of a transaction matching match type. 

We have already loaded 700 rows into one of the sources of the match type. 

Now if i make a change (add 4 ignore like rules in data load mapping)on the recon id dimension of this source of the match type, I get a recalculate icon. I think system is expecting the existing data(700 rows) to be recalculated using new data mapping rules.
