Summary :
As of SAP Release 4.5, the ability to set the postal code field in customer and vendor master records as a mandatory field through Customizing has been disabled. This restriction applies to Customizing via account groups and transaction-specific control. Previously, the field could be set as required in both scenarios, but moving forward, this will only be possible through country-specific Customizing in the field checks for addresses. Correction instructions within the note enable users to revert to previous settings, making the postal code mandatory again, contingent on specific conditions in the country table T005 and city file adjustments.
