Locations|Split Registry entry

Used to enable the Split Location facility.

The Split Location facility is used to manage the location of multi-part objects. It works by tracking the location of leaf parts (a leaf part is one which does not have any child parts). Only leaf objects may be relocated. When a relocation takes place the System propagates the movement up the parts hierarchy, updating the location of each parent provided that all children are at the same location. If all the children are not in the same location, the parent record's location is marked as Split.

With the Parts tab in the Catalogue module it is easy to see where all the parts are located.

Consider the following parts hierarchy:

                         Wedgwood Crockery Collection
                                  (Split)
                                     |
               +---------------------+----------------------+
               |                     |                      |
     Piccadilly Collection   Tower Collection   Man on the Moon Collection
             (Rm 1)                (Rm 2)                (Split)
               |                     |                      |
         +-----+-----+          +----+----+            +----+----+
         |     |     |          |         |            |         |
       Plate  Cup  Saucer     Plate    Milk Jug      Plate      Cup
      (Rm 1) (Rm 1) (Rm 1)    (Rm 2)    (Rm 2)      (Rm 3)     (Rm 4)


The locations are shown in brackets in bold. Since all the Piccadilly Collection is stored at the one location, the collection itself can be found there (and hence it has the same location). The record for the Piccadilly Collection is thus not marked as split. The same applies for the Tower Collection. The Man on the Moon Collection however has parts in different locations (Rm 3 and Rm 4) and therefore the record for the collection is marked as split. The Wedgwood Crockery Collection is also marked as split since its parts (Piccadilly Collection, Tower Collection and Man on the Moon Collection) are not all in the one location.

The Split Location facility is enabled with this Registry entry.

is the IRN of a Locations record designated as the Split location. This is a faux location, that is a Locations record with a Level 1 location of Split.

When splitting is enabled EMu will not allow the location of any non-leaf part to be updated. The location information on the Location tab will be read-only and the Bulk Relocation tool will be unable to relocate a non-leaf part. When a leaf part's location is changed and saved, EMu automatically updates the location of all parent objects, splitting or merging as required. A merge occurs when all leaf parts are at the same location. In the example above if the Plate object is moved to Rm 4, the location of Man on the Moon Collection will be updated to Rm 4 since both the Plate and Cup can now be found at the same location.
