If the subfield you wish to keep is only the first subfield a:

1. Create a normalization rule to make all but the first subfield a blank (replace XXX with the relevant field number):
   rule "make all subfields a but the first blank"
   when
   (TRUE)
   then
   replaceContentsExceptFirst "XXX.a" with ""
   end
2. Save the record. The blank subfields will be removed.

If the subfield you wish to keep is NOT the first:

1. Remove the first subfield only (replace XXX with the relevant field number):
   rule "make all subfields a but the first blank"
   when
   (TRUE)
   then
   replaceContentsOnlyFirst "XXX.a" with ""
   end
2. Save the record. The blank subfield will be removed.
3. Repeat until the subfield you wish to keep is the first subfield.
4. Create a normalization rule to make all but the first subfield blank (as shown above) and Save.
