# Create Grouped Decision Matrices

You can create a decision matrix that groups rows in versions based on a group key and, if necessary, a sub group key. Versions in a grouped decision matrix can have different start date time values. When a grouped matrix is invoked, the group or subgroup keys are considered like input variables, for which you must provide values for lookup.

    For effective creation and management of grouped decision matrix versions, ensure that versions meet the specified criteria.
- **[Create and Configure a Grouped Decision Matrix](https://help.salesforce.com/s/articleView?id=ind.create_the_matrix_version_for_the_first_group.htm&release=264.0.0&type=5)**  
    When you create a grouped decision matrix, the first grouped version is created by default. This version has the same name as the matrix, but is suffixed with V1. Edit the name to give the version a descriptive name, and add a group key or a sub group key value. When you configure the first version of a grouped decision matrix, you also specify the column headers for all versions. You can’t create other group versions before creating the column headers in the first version.

    After creating a grouped decision matrix and configuring the matrix's first version, you can create subsequent versions with different key or subgroup key values and varying row data. You can't create column headers for subsequent versions of a grouped decision matrix because column headers are inherited from the first version.

    When your business requires you to have multiple similar matrices with the same input and output headers, consider creating a grouped matrix. Learn how to create a grouped decision matrix and call it from an expression set version.
