Users will encounter this error below if they have recently switched between different Lookup ID types on their Import Selection.

Error: Deleted ID: The value in the 'XXXXX' column does not exist in the database for the selected record type and alternate lookup ID type when Importing Selections

As mentioned in KB article 100534:

"If you want to re-use an import process in the future, do not switch back and forth between different lookup ID types. Instead, create a distinct import processes specific for each ID type to be re-used".

Customers would like to be able to switch between different Lookup ID types on their existing Import Selections. This would improve the streamlining of the process, rather than having to create distinct import processes for each ID type.
