Hi,
Are you working on a BW on HANA system?
aDSOs are only available in BW on HANA and as a consequence, the related BI Content cannot be used for BW on anyDB.
If your BW system is on HANA, please review SAP Note 2257232 - Do not activate Business Function /IMO/BW_CONTENT. You should activate Business Function /IMO/BWCONTENT after importing one of the below mentioned support packages as soon as the are available:
BI_CONT 7.37 SP16
BI_CONT 7.47 SP16
BI_CONT 7.57 SP9
Best regards,
Sander
