Schema evolution
Updating the data of an incremental table can involve changes to the schema of the source table. The new data can include new columns that are not present in the existing source data, and it can no longer contain columns that the existing source data has. Both is supported by ARIS Process Mining. What happens in these cases?
If you add a new column, the schema of the source table will be extended to include the new column. Existing rows in the source table will not have a value for this column (or in technical terms: the value is NULL).
If your incoming data does not have a column that is part of the schema of the existing source table, the existing column is kept, but the rows that are added or updated from the incoming data will not have value for this column (the value is NULL).
