I has the a mask rule in FDM using FORMATENCRYPT, I apply the rule to in a identification column, this column needs preserve the format and keep the unique values, because is a personal identifciation, and I need that the mask starts at position N (in this case 2).
Now I need apply the same mask rule through masking In-Flight using Transformation Maps,
How I can use the a mask rule in Transformation Maps that keep up the integrity whit the mask that I did with FDM with formatencrypt and comply our needs?.
Preserve the format
Keep the unique values
The mask start at position N
Keep the integrity with FDM.
