The following prerequisites must be met by the comparison instances in a comparison group of specific type to allow a correlation:
Display
Using this group type, completely independent comparison instances can be grouped together, for example, all SAP-CRM related comparison instances, independent of the business object. Therefore, correlation is not possible.
Sequence
Using this group type, you can model the distribution of a business object from one system across many systems, for example, business partners from system A to system B to system C, and so on.
Prerequisites:
All comparison instances have the same mapping and key fields.
Source type and connection data of the target system in a comparison instance (for example, system A to system B) correspond to the data in the subsequent comparison instance (system B to system C).
Distribution
Using this group type, you can model the distribution of a business object from one system to many target systems, for example, business partners from system A to system B, system A to system C, system A to system D, and so on.
Prerequisites:
All comparison instances have the same source system and source type.
The mapping and key fields are identical.
Note
By validating a group, you can check whether the prerequisites are met.
On the Comparison Groups tab page, choose a group of type Distribution or Sequence.
Choose Correlate Group Results.
The system displays a list of executed group runs.
Select a group and choose OK.
Result: The system displays a correlated group result.
