Mapping Profile - export Instance, Holdings and Item - Instance SRS record present

The current implementation of the mapping profile for MARC21export format supports two types of the mapping profiles:

• exporting MARC Bib record as stored in SRS. For the records without underlying SRS MARC Bib record is generated on the fly. The profile include only instance data.
• custom mapping profile that allow user to select fields from the inventory instance, holdings and item records and include them in the exported MARC Bib. All the fields are populated according to the mapping provided in the mapping profile and are generated on the fly.

This feature combines those two mapping profiles options into one and let the user get the existing record from SRS as whole and append to it selected holdings and item fields. If the underlying SRS record is not present, MARC Bib will be generated on the fly.

Once this feature is completed the user will be able to combine export MARC Bib records from SRS and combine them with selected fields from inventory holdings and items records.
