Maintenance Package Hierarchy

A hierarchy which determines which maintenance packages are performed if several maintenance packages are due at one time.

If the maintenance packages are to be performed together at this time, they must have the same hierarchy number (= value).

If only certain maintenance packages are to be performed at this time, these packages must have a higher hierarchy number (= value) than the others. The system always selects the packages with the highest hierarchy number.

If you work with hierarchies and several packages are due on the same date, note that one year and twelve months are considered to be of different length in the SAP system.

1 year = 365 days; 12 months = 360 days (12 x 30)

Examples

The example explains the due date of maintenance packages with different hierarchies for a period of one year (01.01). -31.12). The strategy assigned to the maintenance plan contains two maintenance packages:

Package 1: monthly (1M)
Package 2: every three months (3M)

Example 1

Package 2 belongs to a higher hierarchy than package 1.

Package	Due Date	Frequency	Special Features
Package 1	1M	8 times	Packages 1 and 2 are due at the same time four times. Because only the packages with the higher hierarchy number are executed, package 1 is omitted when two packages are due at the same time.
Package 2	3M	4 times

Example 2

Package 1 and package 2 belong to the same hierarchy.

Package	Due Date	Frequency	Special Features
Package 1	1M	12 times	Packages 1 and 2 are due at the same time four times. The same package hierarchy means that both packages are always due. In this case, neither package is omitted when both packages are due at the same time.
Package 2	3M	4 times
