Import Set Transform is formatting numeric data with a comma
When an import is run from a data source, an integer field is wrongly formatted with a comma.
For example, if an SQL data source contains a five-digit asset number, such as 12345, it becomes 12, 345 when transformed into the ServiceNow configuration management databases (CMDB).
Automatic number formatting can be disabled on a per field basis by adding an attribute to the field's dictionary entry: format=none.
For additional information, refer to Dictionary Attributes in the ServiceNow product documentation.
