Congratulations! You have successfully customized the field selection for material master data using SAP transaction OMN2.

Step 4: Exploring Additional Functionality

SAP transaction OMN2 offers various additional functionalities to streamline your material master data management processes. Here are some notable features you can leverage:

• Copying Field Selection: OMN2 allows you to copy the field selection settings from one material type to another. This feature saves time and effort by replicating the field selection customization for similar material types.
• Transporting Field Selection: You can transport the field selection settings from one SAP system to another using the transport request functionality. This ensures consistency across multiple systems and avoids manual reconfiguration.
• Field Group Maintenance: OMN2 provides the option to create and maintain field groups for material master screens. Field groups allow you to group related fields together and control their behavior, making data entry and maintenance more efficient.
