Data 360: Data Transforms may not save changes when editing existing output DMO or creating new output DMO

When creating a new Output DMO or editing an existing Output DMO within your Data Transform, you may notice an issue with saving it and receive a red banner that states "There is an error saving the DMO in the DB" 

This error occurs when there is an issue within the JSON due to fields having incorrect formatting. Our system reserves double underscore (__) for prefix and suffix and allows this for standard Data 360-related items such as "ssot__", "__c", "__dlm" but not for custom fields. 

Ratkaisu

1. Create a new output DMO in the Transform, save it, and then download the JSON

2. Review the JSON and ensure that fields do not have a generated name that contains double underscore (except "__c" suffix).

  • For example, let's say you have fields in your data and/or formulas where it's listed as "transform_email__address__c" 
  • You will need to change the label suffix from "__address" to "_address" 

3. Once the changes have been made to remove the double underscore, the DMO should save without error.
