Mass processing in master data governance is used for the following tasks:
- It processes multiple selected objects of the same entity type in one step.
- During one transaction, the same changes are applied to this selection.
- It performs multiple transactions (and selections) using the same change request.
- Before starting a mass process, an open change request of the right change request type (single object not checked in customizing) must exist, and you need to be a valid processor.
- Multiple processors can work on the same change request.

The mass change service enables you to replace the selected materials and their selected content with new values per field for all selected materials.
Updating multiple materials is a two-step process. First, you create a change request for multiple materials using this service. Then, you use the Mass Change service to enter the details for the changes you want to make.
How to create a change request is described in more detail in the generic learning units for SAP Master Data Governance, but also in the previous services, for example, in the Create Material service.
Here, we focus on the Mass Change service itself:
Create a change request.
Select the entities for mass change.
Replace or initialize values for the fields with one dedicated value.
Review the results and execute the change.
Assign the mass change request.
