3699719 - Postal Code field Mandatory check not working during Business Partner creation

• When creating a new Business Partner, the mandatory check for the Postal Code field does not work.
• No error message is triggered even when the Postal Code field is left empty, despite it being maintained as mandatory. 

1. Open the 'Manage Business Partner Master Data' app.
2. Click on Create.
3. Select Grouping and add Role Customer.
4. Populate mandatory fields: Name, Language, leave Postal code empty.
5. Click Create.
6. No error message triggered for missing Postal code.

The issue is due to standard system behavior.

If the 'Postal Code Required' flag is enabled, a postal code must be entered for a street address.However, this validation is triggered only when at least one street address field is maintained.The mandatory check is executed when any of the following fields is filled:

• Street
• House Number
• Street 2 / 3 / 4 / 5
• Other City

If none of these fields are entered, the system does not trigger the postal code mandatory validation.
