Starting with a ‘leading' application component, each support package stack (SP stack) describes a combination of predefined and recommended support package levels for all single components included in a product version. Dependencies are defined successive, from top to bottom.
For some components (e.g. SAP GUI or SAP UI) a status is specified for each release that is supported. Other components may be optional, which means that the corresponding support package or patch level must only be fulfilled if you use the components productively.
The same rule applies to SAP Industry Solutions: The SP stack definition of an Industry Solution contains support packages of many different Industry Solutions. But: You only need to implement those SPs that are
Example what a support package stack could contain:
In principle, the specified level of all components must at least be fulfilled in order to apply a support package of the leading component. For most components it is only recommended to have a higher SP level in case there are problems for which no workaround or local corrections are available. If no problems in the systems occur, there is no need to exceed the SP levels until the implementation of the next SP stack.
