Hi Klas, This could be wrong, but since you want to retain 887s with $m subfields that are either A) empty or B) one of your branch codes, could you just add the regex for an empty string "^$" to your existing pattern? So
Delete field 887 if 887$m does not match RegEx m/\Gull|Hjo|Hova|Kabo|Mari|Sksb|Tida|Tikf|Tore|^$/ I'm not sure if that works, basically it relies on Koha's MARC parsing treating a missing subfield as an empty string.
