Define and Maintain Maintenance Level Structure

Explanation

Maintenance level structures represent the subset of the components defined in the monolithic structure which are relevant to this level of MRO disassembly or MRO assembly. When a maintenance level has been connected to a structure, you use the Included setting to associate a component with the selected maintenance level. Just like the monolithic structures of which they are a subset, maintenance level structures are always defined for position parts. In the case of disassembly, this structure identifies the components of the overhaul object which need to be removed according to the given maintenance level for the position. In the case of assembly, this structure identifies the components which need to be installed for the position being assembled.

The maintenance level structures are used during the work scoping process to ascertain the required components based on the maintenance level defined for each overhaul part. The interim orders that are generated from the work scope already contain the required structure information. The supply shop orders take the component information directly from the corresponding interim order rather than from the maintenance level structure itself.

To make use of maintenance level structures, you: 

• attach maintenance levels to maintenance structures - i.e., to MRO disassembly or MRO assembly structures - for a part.
• define for each attached maintenance level the set of components required to dis-assemble or assemble the part for which the structure is defined.

The maintenance status for a maintenance level can be changed as follows:

Prerequisites

• Template structure must have been transferred.
• MRO Disassembly and/or MRO Assembly structures must have been created.
• Maintenance levels must be defined.
• In order to activate the maintenance level, the connected assembly or disassembly structure must have been promoted to Buildable status. Also, at least one of the components in the structure must be included.

System Effects

• Either an MRO Assembly or MRO Disassembly structure will be defined for the particular maintenance level.
• The set of structure components for each maintenance level is defined.
• Any alterations made to an existing structure will be accommodated and shown on the structure thereafter.
