Create holding when receiving a piece and location is changed

Overview

UIREC-48 introduces the ability to select any location when receiving a piece. Based on the "create inventory" order settings we need to ensure that a holding exists for that location. Existing holdings for this piece remain unchanged.

Example

Given:

• createInventory: instance, holding, item
• a piece exists with location: "main"
  • instance, holding and item already exist for this piece.

When the user changes the location upon receiving to "annex"

• a new holding is created for the "annex" location under the instance for this piece
• the item for this piece is "moved" to this new holding
• the "main" holding remains in place.

Acceptance Criteria

• holdings are created as needed when changing the location of a piece as it's being received
• the createInventory settings are honored
• existing holdings remain unchanged
• unit tests are updated
• api tests are updated
