1. Modify a custom CDS View CUSTOM_CDS_VIEW_1 that was created in a prior release.
     
2. Try to export it.
     
3. In Export software collection app, you can find error logs referring to the CUSTOM_CDS_VIEW_1 data sources.
      
4. You try to republish/modify the underlying data sources CUSTOM_CDS_VIEW_2 with the Custom CDS View app.
   
   --> Error: No Association found for Key Field KEY_FIELD_1. No Association found for Key Field KEY_FIELD_2.

An underlying data source CUSTOM_CDS_VIEW_2 has one or more key fields without an association defined.

The affected custom CDS view CUSTOM_CDS_VIEW_2 is a dimension and according to the data modeling rules for a dimension "All key fields except the Representative Key field and the date/time fields must have an association to a Master Data View". See SAP Note 2657021 - Creating Custom CDS Views for Analytical Scenarios

So please first remove the usage of the key field 'KEY_FIELD_1' and 'KEY_FIELD_2' in the dependent objects and then come back to the view 'CUSTOM_CDS_VIEW_2', edit and select a master data view association for the key fields 'KEY_FIELD_1' and 'KEY_FIELD_2'. Publish the view and then add the field again in the dependent objects.
