Mapping between two members of different source systems can be created that is used in the POV of reports. These mappings are required when members in different source systems have different names, but the same meaning (like shown in the example below). If the members have identical names, they will be automatically matched and now entry in the match table is required.
For instance, in case your first source system uses the Period member "Jan" for the month January and your second source system member "January", a mapping between these members results in a POV where selecting "Jan" will result in retreiving "Jan" data from the first source system and "January" data from the second source system.
