Master Data and Planning 

Planning uses master data to validate entries and to store other master data information. If not master data exists for the dimensions of your plan sets, the system cannot check the values entered. In this case, you would receive an error message.

If your set contains the cost centers 100 and 200, but these cost centers are not in the master data, the system displays an error message.

Master data information may be located in different places in the system. When the system searches master data information, it checks the settings in Customizing. The master data being searched for is stored here.
