Missing columns in staging table if the column does not exist in the sample sizeIssue This is specific to the scenario where a column is not getting created in the staging table when it exists outside of the sampling size for an import. This applies to JSON/XML data sources.CauseThe reason for the missing column is because the sample size for creating the columns in the staging table is by default 20.ResolutionTo be able to parse the data in the missing columns, you can add the columns manually as follows: Create the column manually in the staging table open the dictionary entry for the newly created record abovefrom the related links of the dictionary record open "Advanced View"in the "Attributes" field add import_attribute_name=<column label> (this field is comma separated Ex: edge_encryption_enabled=true,import_attribute_name=<column label>)
