Written by Charnjit Singh Dharival

Run the data import and the following error generates:

Orchestrate data flow import has failed. The detailed information is as follows:

ERROR[M002][Microsoft][ODBC Driver Manager] data source name not found and no default driver specified

Import Command: N/A


Please complete the following steps if importing from CSV:

  1. Log into Orchestrate System Manager

  2. select file

  3. Select data import configuration

  4. select data source configuration

  5. Click New

  6. select ODBC data connections from Data Source Type dropdown list

  7. Click Next

  8. Click Manage ODBC source

  9. Select System DSN tab and select the relevant name e.g. CSV import, 32 bit, Microsoft Text driver

  10. Click Configure

  11. Click Select Directory

  12. Click OK


You may find a data sequence is missing from the data flow or a field mapping is missing in a existing data sequence. Also, the data source may be directed to the wrong database. Please check the following:-

  1. Log into Orchestrate System Manager

  2. select file

  3. Select data import configuration

  4. select data flow configuration

  5. Select CSV import and click Edit

  6. Check each bulk copy into table data sequence and click settings

  7. Check CSV data source is selected from drop down list

  8. Check source table has the name of the CSV file e.g. data sequence Bulk Copy into Table orc_Items should contain Items.CSV in the source table field

  9. Check there is a correct source expression in the equivalent Orchestrate Field Name

Note: if no CSV is configured, you can show the user how it works but cannot create all the data sequences. This would be chargeable consultancy and you would need to raise a self gen case.



Alternative solution is:-

  1. Launch ODBC from windows

  2. Select System DSN tab

  3. select Add button and enter a name e.g. 'CSV Import'

  4. Launch Orchestrate System Manager
