Validation:

Guidance: This error occurs due to the surname containing two separate words, which is flagged by an SBR (Standard Business Reporting) validation rule.
For example, if the surname entered is “Anna Def”, the space between the two words triggers the validation error.
Solution:
To resolve the issue, please modify the surname format and resubmit using one of the options below:
Option 1: Use a hyphen
Anna-Def
Option 2: Combine the surname into one word
AnnaDef
Either format should pass validation and allow the form to lodge successfully.
Additional Notes:
SBR does not validate names in full context.
In cases like this, combining or hyphenating the surname is acceptable and will not affect the lodgment outcome.
Once the submission is accepted, no further action is required.
