Hi Community,
We are loading several tables form a Azure data lake Gen2 (CDM folders). The system is in productive use since a few months where we built several (complex) measures and segments.
Recently we recently realized import errors on several tables where the error message says:
Error: Number of columns in source data file does not match the number of attributes: {AttributeCount} defined in the source data schema for the entity '[table name]'
(The data still seems to load correctly)
When I try to review/edit the data source, CI tells me I have to first remove the table from all relationships/measures/segements etc. This would be a massive task and cause a downtime for several days (basically we would have to "rebuild" almost everything).
How can I find out which columns are causing the issue? Is there any other way to analyze this and "reset" the data schema within CI and fix this?
