ABAP prog with Call Transaction to SU01 will not add roles in a CUA client

I am modifying a current ABAP program that works in a non-CUA client to hopefully execute in a CUA client. This program performs a Call Transaction to tcode SU01 and adds roles to an existing user. I used tcode SHDB to identify the new BDC commands needed for CUA when using tcode SU01. When executing the program in the CUA client it does not save the roles to the user. There is no error message or abnormal termination.

When I assign the role to the same user that's referenced in my program directly with tcode SU01 it works fine. Its just when I run the ABAP program the role assigment is not retained. I opened a Customer Message with SAP and they referenced OSS Note 93802 and said this was a consulting question. My program is not abending as referenced in Note 93802, it just does not add the role.

Has anyone been able to get this to work in a CUA client?
