Rename Serial

General

The Rename Serial functionality is used to change a part number and/or serial number on a VIM serial.

Changing the part number and/or serial number of a serial is a common practice within the aviation maintenance industry. A serial may be modified in such a way that the part is transformed from one part number to another. The modification may be performed when the object is In Operation if it is a minor modification, or during overhaul if it is a modification (no matter what kind) that is planned to take place during overhaul. The Rename Serial functionality also supports occurrences where the part number registered on a serial is determined to be incorrect and needs to replaced with the new valid part number.

In order to successfully rename a serial several prerequisites must be fulfilled. Furthermore, several validations will be performed in IFS/Vehicle Information Management (IFS/VIM), IFS Distribution and IFS Manufacturing before the serial is renamed.

For more information on the validations performed in IFS/VIM refer to the online help file Rename Serial.

For more information on the validations performed in IFS/PARTCA refer to the online help file Rename Serial Part.

Performing a Serial Rename

Before a serial can be renamed there are several prerequisites that need to be fulfilled. The primary prerequisite used when determining if a serial rename is allowed is based on the value entered in the Current Position field for the from-serial and to-serial.

The from-serial must have the current position In Facility, In Inventory, Issued (to a shop order or work order), or Contained (and the top serial has the current position In Facility, In Inventory, or Issued, i.e., to a shop order or work order. Note: It will not be possible to reverse the issue transaction once the serial is renamed.

The to-serial (if existing) must have the current position Unlocated and an operational status of Renamed.

Note: In the part serial catalog, it is only possible to rename a serial part that is stored in the inventory, provided that no reservation exists for the serial part and that it is not defined as a VIM Object, Equipment Object, Project Delivery Object or a Plant Design Object.

Part Property Settings and the Rename Serial functionality

Property settings are evaluated and updated when the part number, serial number or both the part and the serial number is changed on the serial. The following sections give a detailed description of the properties that are evaluated.
Note: For the properties which are not mentioned in the list below, the serial will retain the properties that are valid for the to-part number. It is essential that you perform the renaming of a serial carefully since alternative possible implications may arise as a result of the rename.

Serial Rename Tracking

It is possible to track a serial's life through the serial number and part number changes.

The Renaming group box on the Part Serial/General tab holds information about the serials preceding part number and serial number, as well as information of the part number and serial number this serial has been renamed to.

Note: You can rename a serial multiple times. The Part Serial Rename History window holds the full backwards and forwards information of a serial.

System Effects

The following system effects will take place once a serial is renamed.

Inventory Transactions and the Rename Serial functionality

If the serial number is changed for a serial, the SERREN+/SERREN- transactions are used to handle the serial number change. If only the part number or both the part number and serial number is changed for a serial, PARTREN+/PARTREN- transactions and PRENREVAL+/PRENREVAL- events are used. Observe the following example:

Example: A serial with part number A and serial number 1 is renamed to part number B with serial number 1.

First the from-serial A/1 is issued from inventory at value 100.

Transaction: PARTREN-  
Event: PARTREN- Debit 100 M191
Event: PARTREN- Credit 100 M1 - Inventory

If the to-part number is using Inventory Valuation Method Standard Cost = 200 the to-serial B/1 is received into inventory at value 200.

Transaction: PARTREN+  
Event: PARTREN+ Debit 200 M1 - Inventory
Event: PARTREN+ Credit 200 M191
Event: PRENREVAL+ Debit 100 M191
Event: PRENREVAL+ Credit 100 M8 – Inventory Value Increase

If the to-part number is using Inventory Valuation Method Weighted Average the to-serial B/1 is received into inventory at value 100.

Transaction: PARTREN+  
Event: PARTREN+ Debit 100 M1 - Inventory
Event: PARTREN+ Credit 100 M191

A new weighted average has to be calculated for the new part/site/cost level.

If the to-part-number is using Inventory Part Valuation Method FIFO or LIFO the to-serial B/1 is received into inventory at value 100.

Transaction: PARTREN+  
Event: PARTREN+ Debit 100 M1 - Inventory
Event: PARTREN+ Credit 100 M191

A new entry to be added to the FIFO/LIFO table.
