Verify Off Log Structure

Explanation

Use this activity to analyze a structure that is currently disassembled. Ideally, this activity should be performed prior to the initiation of the structure assembly process. The purpose of this activity is to ensure that the Off Log structure is correct.

First and foremost, you need to identify new serials in the Off Log, and define appropriate tasks for these serials and the belonging structures. An Off Log contains details on the serials that have been disassembled as well as details on the serials included in the structures of the disassembled serials. Furthermore, this activity can be used to change work scope tasks when an interim order structure is released, and disassembly is in progress.

Different Part Found scenarios in an Off Log Structure

Due to certain circumstances you may have to receive an unexpected serial(s) to the Off Log. Unexpected in that the serial(s) received is different to the serial(s) expected for the Off Log. This is generally referred to as a DPF (Different Part Found) scenario. Different part found scenarios are identified and resolved through this activity. When a DPF occurs against a position part (or structure position) that has more than one serial part, the system cannot automatically identify the serial that ought to be removed from the work scope. For that reason you need to manually map the expected and new serials against each other by using the Change Work Scope Tasks/Map Serial Numbers tab. If new serials are received during disassembly, and tasks have been defined for these serials, you are required to perform the serial mapping task for the work scope.

If all expected serials have been received in the work scope or in other words if DPFs do not exist, the received and expected serials are mapped automatically.

If for some reason a structure mismatch occurs, for instance the details in an Off Log differ to the details you (the Engineer) believe should be displayed in the Off Log, serial parts that are not already disassembled in the structure can be adjusted in IFS/Vehicle Information Management. 

Prerequisites

• A running work scope must exist.
• Disassembly has started.
• Assembly has not started. (if you intend to alter the off log). Note: Once an assembly starts the off log becomes static.
• New serials are found during disassembly for structure positions (position parts) holding a quantity higher than 1 for serialized parts

System Effects

• The actual serial structure for the overhaul object (i.e., work order part) can be examined.
• If new serials have been added to the Off Log during disassembly, they should be examined for due modifications or LLP requirements. If so, the modifications or LLP requirement should be added as new tasks to the existing work scope.
• The Off Log is updated for position parts having serialized parts with quantity higher than one, and identification of tasks for new serials in the work scope can continue.
• Tasks for old serials that was not in the structure during disassembly will be displayed in Define Work Scope/Superfluous Tasks or Change Work Scope Tasks/Superfluous Tasks and these tasks should be removed.

Procedure

Follow this procedure to verify an Off Log Structure:

1. Open the Change Work Scope Tasks window.
2. In the WO No field, query (F3) for the work order of your overhaul object.
3. Click the Off Log tab. Details on the serial structure of the overhaul object will be displayed. Verify the information shown on this tab.

Follow this procedure to add new tasks to an existing work scope:

1. Open the Task Summary window.
2. In the Work Order field, query (F3) for the work order of your overhaul object.
3. Click the Off Log tab.
4. Select the row that contains details for the new serial, right-click, and then click Change Work Scope Tasks. The Change Work Scope Tasks window opens, with the selected serial as the top serial.
5. Include all modifications and LLP tasks that you require for the new serial and/or its components in this window and its tabs LLPs and Modification.

Follow this procedure to map serials, for instance, due to a DPF scenario:

To perform this procedure you should have received different serials than expected for position parts (or structure positions) having serialized parts with quantity higher than one, or receiving the same serial as expected, but in a different place in the structure.

1. Open the Change Work Scope Tasks window.
2. In the WO No field, query (F3) for the work order of your overhaul object. This will be the work order for which a work scope was created.
3. Click the Map Serial Numbers tab. The table on the left displays all serials of a structure before assembly. The table on the right displays the new serials that have been included in the structure during its disassembly.
4. To work on the same position part number in the two tables you can query manually in both the tables. Observe the check box Mapped is already selected if you receive the same serial as expected. 
5. Select the Show Unmapped option in order to populate both tables with the serials that are currently not yet mapped. Select one record from each of the tables and click Map. Note that if the Position Part of the two selected records is different this option cannot be selected.
6. Select the Transfer option to transfer all 'Mapped', and not yet transferred, records to the 'Off Log' All transferred records will be marked with Off Log Updated check box.
7. If you want to 'reverse' the transfer action select already transferred line and select the Undo Transfer option. 
8. After the undo transfer process or on a not yet transferred record, you can select the Unmap option to clear the Mapped check box.
   Note that on the 'mapping' window if you select a line on either side, the system highlights the corresponding mapped 'partner' in the other side.
