A custom column has been created on the table UNSAccountB and the group property set for this column.
The expectation is for the column to show up with a separate tab on the UNSB-MasterData-Form named like the group property instead of on the generic "Custom" tab. However, this does not occur.
This behaviour is expected, as the group property has another meaning for the table UNSAccountB. The group property determines from which target system the information is depicted.
Currently for UNSB-Target systems the name of the tabs for custom columns cannot be configured.
An enhancement request (#27728) has been created. The product team will evaluate the request and this feature may become available on a future release of the product.
