In the CDC application there is a tab strip called Comparison Group. In this view you can group comparisons logically (e.g. by systems to be checked, data to be checked). The comparison group can be used as filter criteria in the administration view and the grouped comparisons will be started and stopped together as a common group run.
There are four group types available for different use cases:
- Display is used to just group comparisons according to logical criteria without additional functionality
- For example you have comparisons for business partners separated per each country, or financial documents per company code. The result shall be shown individually, e.g. because there are different responsible people to be notified.
- You can even group completely independent comparisons for any reason, e.g. filtering on administration screen.
- Distribution is used to model a distribution from one system into many dependent systems (1:n relationship)
All comparisons must have the same source system and source type, and the mapping and key fields must be are identical.
- Using a correlation feature you can see an overview to which target systems each record arrived or is still missing.
- Sequence is used to model transfer of data across a chain of systems
- All comparisons must have the same mapping and key fields. The source type and connection data of the target system in a comparison (for example, system A to system B) correspond to the data in the subsequent comparison (system B to system C).
- Using a correlation feature you can see an overview for each record how far it was moved through the system chain.
- Split is used for automatic groupings of split comparisons as a result of the corresponding mass procedure.
- You have split a very large comparison into smaller junks, but they are still grouped so you can run them in parallel.
- You can see a correlated result, representing the sum of all differences
Procedure to maintain Comparison Group
- Choose Comparison Group tab
- Select the Comparison Group type you wish
- Choose the Create Group button on the right
- In this view you give name and description to the newly created group
- After assigning the comparisons to the group save your entries
- With Start Group you schedule the comparison run for your group
- With Show Group Result you can access the correlated result
Procedure to maintain Comparison Group Type
In case you need your own group type with your own correlation logic, you can define a custom-specific group type as well.
- Choose Comparison Group tab
- Select Create Group type
- In this view you give name and description to the newly created group. In addition provide the name of the class implementing the interface IF_DSWP_CDC_GROUP with your custom logic, e.g. by redefining the method CORRELATE.
- After saving your entry, you can start using the new group type for grouping comparisons
