Which parts must be maintained at what intervals?
The individual components of your technical objects must be maintained at different intervals. For example, an external visual inspection for rust and water-tightness is performed on the water pumps at your company each month. However, the wear in the gear box for the pump is only checked once every year.
Maintenance Strategy: Packages and Parameters
The maintenance strategy consists of several maintenance packages and incorporates the scheduling rule for preventive maintenance. Task lists are assigned to maintenance strategies.
Time-Dependent Maintenance Strategy ParametersStrategy unit
Scheduling indicator
(time: calendar-based; time: using key date; time: using factory calendar)
Call horizon
Shift factors and tolerances
Factory calendar
Package sequence and where-used list
You can assign any number of maintenance packages to a maintenance strategy. Note that the maintenance packages for a strategy shouldn't have different cycle units (for example, month, year). A strategy consisting of one month and one year should be defined as one month and twelve months, respectively.
Managing Authorization
If you want to restrict the access of maintenance strategies, you can assign authorization groups in Change Maintenance Strategy (transaction IP11). Only the users who belong to this authorization group can modify the strategy.
To manage the authorization of a maintenance strategy, you must activate business function LOG_EAM_CI_9.
If you want to use this feature, the system administrator must assign the authorization groups to the users with the I_BEGRP authorization object.
Maintenance Package
Hint
If you set one of the two buffers to 0, the planned date can still be displayed later in the order.
Hierarchy
The hierarchy of maintenance packages defines whether all maintenance packages that coincide should be executed, or whether certain maintenance packages should be ignored. For this reason, a hierarchy level is assigned to each maintenance package.
If maintenance packages with the same hierarchy level coincide, these maintenance packages are executed.
If maintenance packages have different hierarchy levels, the maintenance package with the lower level isn't executed.
For example:
For vehicle maintenance, the spark plugs are to be cleaned every three months and changed every six months. In order that cleaning and changing aren't both carried out after six months (which would mean that the spark plugs would firstly be cleaned and then thrown away), the 6-month package (change spark plugs) is assigned a higher hierarchy than the 3-month package (clean spark plugs), and the latter is deactivated.
