Symptom
I receive the following error during Load phase of ETL/T&L in Process Intelligence:
"Error during update of linked process: Failed to upload to pex-backend. Reason: Target responded with 'Bad Request': The following process views reference attributes, which have been removed from the eventlog. Either add the attributes [x,y,z] back to the eventlog or fix the process views by saving them again [a, b_c]. This will remove the removed attributes from the process view."
Cause
This error occurs when certain attributes that appear in Process Views are removed from the Business Object transformation SQL scripts.
Resolution
To resolve this issue you need to hide the attributes from the Process Views.
