Authorization Problem in /tmwflow/reporting

Hi everybody

I just created a security role for users that need to access /tmwflow/reporting. The users should just be able to see the created transaction type "ZDHF" which I select under "Transaction Data" in the transaction /tmwflow/reporting. After selecting the apropriate solution and start the query I get the error, that I don't have the authorization rights.

When I check with SU53 (or use a System Trace on authorization) I see that it checks on the authorization object "CRM_ORD_PR" on the Transation Type SDHF (and not only ZDHF - what I would expect) also and therefore doesn't work.

Why does it check SDHF and how can I get around this?

Thanks for your help!
