Question: can I use field mappings in any version of OAK!Merge?
Answer: yes, field mappings are included in Basic and up versions.
Note: In the Basic version you can save and use mappings. This is not the same as saving and using profiles. Mappings are only the field mappings. The profiles include the mappings AND the log-in/password, type of source and file name. Profiles are required for unattended automated merges. Profiles are not included in Basic.
If you create and reuse field mappings you can import files repeatedly without having to redo the field mappings each time. The field order and field names need to stay the same.
