Purpose:
In some cases (call number and electronic access) multiple inventory holdings fields will be mapped to the same MARC field but different subfields. When the mappings are processed then the different data will need to go into separate subfields

Scenario 1:
Given: mapping for call number
When: prefix or suffix is selected
Then: prefix data will go for example to: 825 $k field, call number will go to 825 $h and suffix data will go to 825 $m

Note: similar behavior will be for electronic access
