2886241 - How to Change Duplicate Tax Number Category from an Info Message to an Error Message in SAP S/4HANA Cloud


  • There is a requirement to change duplicate Tax Number Category from an Info Message to an Error Message in SAP S/4HANA Cloud.
  • Business Partner Fiori Apps such as Manage Supplier Master Data do not throw any info/warning or error message when two Business Partner have tax number.
  • When a new vendor with the same VAT Registration number, the system does not block the vendor creation. Only on App Maintain Business Partner, a warning message is displayed but an error message is expected to block the creation.



Reproducing the Issue

  1. The duplication check for a Tax Number Category has been customised to be activated as per the steps in KBA 2886187.
  2. The system raise an info message when a Duplicate Tax Number is entered into a Business Partner.
  3. The system still allows the business partner to be saved with duplicate tax number.


There are some scenarios whereby more than one Business Partner could have the same tax number as another. Therefore, by default a warning message is thrown in App Maintain Business Partner.

The following steps must be followed to convert this warning message into an error message:

  1. Open the Manage Your Solution App.
  2. Select "Configure Your Solution".
  3. Search for the SSCUI 103601 - Change Message Control for Duplicate Tax Numbers.
  4. Press Configure.
  5. Enter the "Application Area": BUPA_TAX.
  6. Change the message 400 from an Info Message to an Error message and save.

With the current system design, the Fiori Apps such as "Manage Supplier Master Data" cannot display Info or Warning messages as the Fiori Apps show their Messages after the save has occurred and this is why, currently only Error messages are returned.

Therefore, once the above mentioned changes are done in SSCUI 103601, the same error message is also thrown in BP Fiori Apps such as Manage Supplier Master Data.
