How to load username by HDL

Content

Hello experts,

I'm going to massively load usernames by HDL and I'm using the following format:

METADATA|User|PersonNumber|Username
MERGE|User|2000127|TEST

METADATA|UserRole|PersonNumber|RoleCommonName|AddRemoveRole
MERGE|UserRole|2000127|ORA_PER_EMPLOYEE_ABSTRACT|ADD

However, I get the following error message: UserId is null.

I have always successfully used in the past the previous format and I was able to load usernames.

Has something changed with last releases? If so, which format should I use to successfully load usernames?

Thanks in advance for your time!

Kind Regards

Valerio
