Calculate Maintenance Levels From Baseline
Explanation
This activity is used to apply the work order part maintenance level baseline for the entire structure of the
maintenance overhaul object (work order part) or for a subassembly within the structure.
A revision is typically selected when the work scope is first created, when a different revision for a
subassembly is required or when the off-log changes due to different part found scenarios.
To calculate maintenance levels, click Calculate Maintenance Levels from Baseline in the
Define Work Scope page. In the dialog that opens, enter the required revision number.
Verify the results in the tree navigator and in the Work Scope - Part/Assign Mx Level
tab. In here, the Expose All Affected Parts option indicates whether all affected parts of assigned
maintenance events (i.e., modifications and LLP maintenance events) for a sub-assembly are included in the specific
maintenance level. This information will help you to choose a correct maintenance level for the sub-assembly.
Note: This activity can be performed after the creation of the interim order structure by release of the
work scope and after the creation of the supply shop orders by the release of the interim order structure.
Prerequisites
- Disassembly, disposition, assembly structures and routings must be defined for the position parts
corresponding to the part for which you want to perform this activity.
- Maintenance level structure and routings must be defined for all maintenance levels of the sub-assemblies
and/or piece parts considered for the calculation.
- Customer maintenance baselines and modifications should be defined in IFS/Fleet and Asset
Management.
System Effects
- A revision of the position part will be selected and used for work scope definition.
- The off log for the work order is created based on the serial structure in IFS/Fleet and Asset
Management.
- Work scope maintenance records for the part and all sub-assemblies are created. These work scope maintenance
records are for the current manufacturing revision.
- Maintenance levels for these work scope maintenance records is set based on the maintenance level baseline
for the overhaul part.
- Disposition maintenance levels for the piece parts are set with the following priority.
1. Disposition type maintenance levels defined for the piece parts on the maintenance level
baseline.
2. Set maintenance level for the immediate parent sub assembly. if the
Site/Manufacturing/MRO/Copy Parent Mx Level to Piece Parts is selected.
- Maintenance levels for the part and all sub-assemblies which expose affected parts are flagged by the
system.
