Change Catalog Number
Explanation
This activity is used to change the catalog number for an entry in the template structure.
If Complex Assembly MRO is used:
Catalog numbers are used to generate position parts for the template structure. The structure that is
transferred to Manufacturing is based on these position parts. Position parts operate as a placeholder for the set
of parts (prime part and alternates) that are valid for a particular position in the structure. Following rules
apply when changing the catalog number:
- The catalog number must be unique within the structure of the overhaul object. The system will check whether
position parts based on the new catalog number exist for the template.
- The position part that is generated for the structure entry is not used in manufacturing or is used in
product and routing structures that are not in status Tentative, Plannable, or
Buildable.
- The position part is not included in a released work scope.
To identify valid parts for a given position, alternates are required to have the same catalog number as the
prime part. Note: The catalog number is applied to the structure position, and is the same regardless of
which part is installed in the structure position. However, an alternate, e.g., template part, can have a separate
catalog number, and the structure position within that template can have their own catalog number. Following rules
apply:
- If the alternate has a catalog number that is not the same as the prime part's catalog number, no new
position part is created and no structure line is created in the transfer. If the alternate part has a different
catalog number, the transfer does not use this catalog number in the creation of the structure. The
alternate's catalog number is only used if the alternate part is the prime part in another template
structure.
- If the alternate has a structure, all structure entries should have a catalog number.
- If the catalog number of a structure entry is the same as the catalog number of the corresponding structure
entry for the prime part, a position part or a structure line is created. If the same catalog number is used for
the structure entry of the prime part and alternate, the structure positions and quantities should also be
same.
- If the catalog number of a structure entry is not the same as the catalog number of the corresponding
structure entry for the prime, a new position part is created and a new structure line is added as a child to the
position part created for the prime part.
Prerequisites
- If the Allow Non Unique Catalog Numbers option is enabled, the new catalog number must be unique
within the template and all templates above and below in the structure.
If Complex Assembly MRO is used:
- The position part must not be used in a tentative, plannable, or buildable product and routing
structure.
- The position part must not be included in a released work scope.
- Alternate part structures must have the same structure position and same quantity if they have the same
catalog number. This is due to the lookup that finds the assumed serial during the disassembly of shop orders in
Manufacturing.
System Effects
- To reflect changes in manufacturing structures, the top part can be retransferred to manufacturing.
- When the template structure is retransferred:
- A new position part is created for the new catalog number.
- The position part reference in Part Catalog is updated and all the position parts based on the old
catalog number will be deleted.
