The Master Data Generator creates planning objects for an information structure on the basis of existing or planned data. You access the Master Data Generator in standard SOP with Product group ® Generate master data.

If you wish to run the Master Data Generator, SAP strongly recommends that you do so before you start using Sales & Operations Planning. Background processing is the most suitable mode of execution for this program.

The Master Data Generator functions similarly in standard SOP and flexible planning (see Master Data Generator in Flexible Planning). However, when you run the Master Data Generator in standard SOP, the internal planning objects of the standard SOP information structure, S076, are generated from the master data of another information structure. This is any information structure specified by you which contains the characteristic "material". If "plant" is also a characteristic of this information structure, a planning object is created in S076 for each combination of material and plant found in it. If "plant" is not a characteristic of the source information structure, planning objects are created in S076 for each plant in which a material is managed in the system (this information is stored in the material master record).

The generated planning objects are stored on the database but are not visible to the end user. However, they are needed in standard SOP for the copying of data to information structure S076 with mass processing.
