Hello all,

I have an issue: I need to do a check on the file imported into ARCS via Data Management.

In Data Management there is one main parent mapping, valide for each single location. For each location, I'd like to check if the file that will be imported into each of them will contain only a list of values; if an unexpected value will be present in the file, then the upload of the file must go KO.

For example, for the location A could be only the value A for the Attribute "Account"; for the location B could be only the value B for the Attribute "Account".If there is the value B in the file that is imported in location A, the upload must go KO.
