Sequence Instructions within a Task Code

Explanation

This activity is used to define a network of instructions and subtasks within a given task code (maintenance code, modification code, condition limit, fault function, life limit or post maintenance check definitions). This is done by defining predecessors for instructions within a task code and for subtasks within an instruction, which would then represent the optimized sequencing of task codes to be performed within a maintenance visit. Note that the procedure for defining the network of subtasks within instructions is described in the activity Sequence Subtasks within an Instruction.

The purpose of this activity is to support the process of sequencing the work for regular maintenance orders with connected tasks (i.e., non-ELS maintenance orders).

Prerequisites

To perform this activity, instructions must be defined for a task code (i.e., maintenance code, modification code, condition limit, fault function, life limit or post maintenance check definitions).

System Effects

• The instructions which are defined for a given task code will be sequenced.
• The sequencing will be transferred to the work order (in IFS/Work Order Management) when the corresponding maintenance order is released.

Procedure

General Procedure:

1. In the Operation Number field, enter the instruction (operation). Use the List of Values to select a valid value.
2. In the Preceding Operation Number field, enter the predecessor. Use the List of Values to select a valid value.
3. Save the information (F12).

For Maintenance Codes:

1. Open the Instructions per Maintenance Code window and query (F3) for the necessary part revision and/or maintenance code.
2. Click the Sequencing tab and create a new record (F5).
3. Continue with the steps described under General Procedure.

For Modification Codes:

1. Open the Modification Details window and query (F3) for the necessary part revision and/or modification code.
2. Click the Instructions tab and then click the Sequencing subtab.
3. Continue with the steps described under General Procedure.

For Condition Limits:

1. Open the Condition Monitoring Program window and query (F3) for the necessary part revision.
2. Click the Instructions tab and select the necessary condition limit.
3. Click the Sequencing tab and continue with the steps described under General Procedure.

For Fault Functions:

1. Open the Instructions per Fault Function window and query (F3) for the necessary fault function.
2. Click the Sequencing tab and create a new record (F5).
