Customer Master Data

1. Business-User Summary

The Customer Master is the central repository of all information related to a customer. It dictates how the system interacts with the customer during sales, shipping, billing, and accounting.

Business Warning: Bad customer master data causes wrong pricing, wrong delivery, wrong billing, and credit issues. If the master data is wrong, every transaction created for that customer will be wrong.

2. Why This Process Matters

Accurate customer master data is the foundation of the Order-to-Cash cycle. It automates data entry in sales orders, ensures regulatory and tax compliance, and defines payment expectations to manage cash flow.

4. Key Concepts

Customer Account Groups & Number Ranges

Account groups classify customers (e.g., Domestic, Foreign, Intercompany, One-Time Customer). The account group determines which fields are mandatory, optional, or hidden, and dictates the number range assigned to the customer ID.

Blocking Reasons

Customers can be blocked centrally or for specific sales areas. Reasons include bankruptcy, legal disputes, or quality issues. An order block prevents creating sales orders, while a billing block stops invoicing.

5. Fit-Gap / Customization Notes

• GAP: Ameco requires specialized industry codes that do not fit in standard SAP fields.
• Resolution: Custom fields were added to the General Data tab to capture "Ameco Industry Sub-segment".
