Issue description

Many libraries use external sources to populate Inventory, e.g. via Union catalogues. In those cases, new instances, holdings and items will be generated in FOLIO Inventory as soon as a library adds an ietm to an instance in Union catalogue. For those resources, the ususla PO and POL is created in FOLIO Orders, "Create Inventory" field is populated (via the drop-down) with "None", "Instance" or "Instance, Holdings". When the resource then is in receiving process, there is no way to add an accession number or barcode in FOLIO Receiving - neither via Number generator nor via manual input, as the relevant fields are deactivated when no item is created in Inventory.

Requirements analysis

Option 1

• Receiving app: Make the fields "Accession number" and "Barcode" and "Call number" active, no matter which "Create Inventory" setting is used on the POL.

Option 2

• Receiving app: Add an additional fields for "Accession number" and "Barcode" and "Call number" that are independant from the "Create Inventory" setting.
• The generation of numbers via the Number generator needs to work for these fields.
