Mass Processing enables you to update multiple master data records at a time. This function is available for the product master, business partner (including customer and vendor), business partner relationships, and custom object domains.
Mass processing uses the same technical foundation as the consolidation capabilities of MDG, allowing you to combine the features in a flexible process configuration. Packaging, queuing, and parallelization contribute to enhanced performance even when processing large volumes of data. Let's look at the steps involved in the mass processing of multiple master data records in the following video.
The figure Mass Processing: Overview provides a brief overview of the different screens during mass processing of material master data.

To update multiple records, select the fields and records you want to modify. The system then displays a list of fields to modify based on your selection. On entering the changes, the system provides statistics on the modified fields and validates the data. Once the data is validated, it is then activated. Activation copies the data from the staging area to active memory, enabling the system to use it in business transactions.
