Modify an existing EDM
As part of protecting PII, I have, in production, a single column EDM looking for US SSN's about which my Company cares. I have built policies and associated response rules around this particular EDM profile. Taking a baby-step forward, I now need to include the safeguarding of Canadian Social Insurance Numbers. As the SIN is part of our PII definition, I think that it makes sense to modify my existing single column EDM to now be a two column EDM - one column US SSN the other column CA SIN. Unfortunately, I do not see a way to make such a modification. It appears as though I must create a new EDM with two columns, map the fields appropriately, and then go back and change my existing policies to use this new EDM.
Can anyone point me in the right direction in this regard? Must I create a new EDM and modify my policies? Can I not modify an existing EDM to add a column and avoid all the associated policy changes?
Thank you in advance!
