One of our clients noticed that while creating or updating a supplier or customer record in Sage X3 they need to enter the city and region, and postal code as per the address. This manual process is time-consuming. As a result, they inquired whether there was a way to streamline the process.

So we have implemented a customization on the Postal code field in the Customer and Supplier master.
Managing supplier and customer data efficiently is essential for smooth operations in our ERP system. It streamlines this process with a smart feature that automatically populates the City and Region fields in the Supplier and Customer Master records based on the Postal Code entered.

Let’s examine the functionality in more detail:

According to this requirement, a user first visits the supplier master screen, and when a user inputs a Postal Code while creating or updating a supplier record in Sage X3, the system intelligently fetches and fills in the corresponding City and Region fields.
