Hi All,

I found the solution, the problem was that i didn't have the last SP of WCEM 3.0.

I have an another question for you guys:

Is it possible to customize(rename the fields) the workcenter/menu on the WCEM?

Thanks a lot for your help

Hi Anass,

yes, it is. After having created a module in customer namespace, create/ maintain your own 'myaccount.xml' file. The file will be taken into account during the initial merge mechanism.

Best regards,

Steffen
