Define Number Ranges for Customer Account Group

Updated Jun 23, 2022

In this SAP SD topic, we have explained the step-by-step process to define the number range for the customer account group along with the proper screenshots.

In order to create a number range for the customer master, the number range should be created first and then assigned it back to the customer group. An SAP user can define different number ranges to assign it to different customer account groups in other words a single number range can be assigned to various different customer account groups.

Once the user assigns the number ranges to the customer account group it establishes a link between them. Once the number ranges are assigned to the customer account group, then the account group is eligible to use while creating a customer master.
