Trying to execute a recipe with a multi-column fold on a Google BigQuery table gives the following error:
In-database (SQL)
You cannot use this engine:
Not supported settings for 'MultiColumnFold'
processor: Not translatable to SQL
Non-selectable
Local stream Output dataset is in Google BigQuery
Any suggestions for moving forward?

Hi,
This error indicates that you cannot use this particular processor in this prepare recipe. The reason being that when DSS can only write SQL to Bigquery and the "Fold multiple columns" processor has settings that makes it impossible to translate to SQL.
If you really need to implement this processor, then you will have to go through GCS instead.
