The expected variables on the RITM table are not visible for end user.
Problem
The RITM view may differ from the order form for the visible variables.
Cause
The end user does not have write access to the variables field on the RITM table.
Solution
End user must create a new field-level ACL for write access to the variables field on the RITM table with a required role as x_vmw_cloudservice.vra_end_user.
