3261924 - Error 'Select a key from the allowed namespace' when using the SSCUI 104758.


Error 'Select a key from the allowed namespace' occured when creating custom Tax Number Categories 'TR3' with the SSCUI 104758.



Reproducing the Issue

  1. Go to SSCUI 104758:Define Tax Number Categories
  2. Create a custom Tax Number 'TR3'


Standard behaviour


Create similar custom tax number categories with a prefix 9, as shown in the below format:

9<Country/Region ISO Code><Tax number>

The standard settings follow a naming convention of a prefix number 9, two letters, and a number.

For example, the categories in Israel we should use '9IL1'.
  • The custom tax number category should start with the number 9.
  • The next two letters are the ISO code of the country/region that the tax number is used in.
  • The last number is a sequential tax number, which is in the range 1–6.
The number is important if you replicate business partners to customer or vendor master records in SAP S/4HANA Cloud. The number controls which Tax Number field in the customer or vendor master this tax number is replicated to.
