Cannot Add Custom BO in offline settings

[j_hemminghaus]

Hello,

I created an offline enabled custom BO with access context (RelevantForAccessControl) on Employee. For the access context I followed this guide.
I created a query in studio, since the SADL Query in UI Designer does not have access to the backend runtime. This Query is bound in my OWL and property "UsedForOfflineSynch" is set to true.

However, if I select my OWL in the offline settings I receive an error message "OWL cannot be used, since not SADL enabled".

How can I resolve that error message withouth loosing my access context?

Any help appreciated.

Regards,
Jacqueline
