Not able to add/ create useres in BPC NW10 Admin

Hi Experts,

We installed CPMBPC 801 and HANABPC 801 in our BW731 sytem which is running on HANA.

I activated ENVIRONMENTSHELL with suceess messgae.

When I login to Admin to add users, the Add button is disabled and there is a error messgae  -

"Unhandled Error (HTTP Status 500):unmarshal.invalid.xml".

I followed Notes 1649819 and 1615644. Reactivated the ENVIRONMENTSHELL but still same issue. Not able to add users.

I have assigned all BPC specific roles as well as SAP_ALL to my id.

Regrads,

Sandeep
