Links mapping error

Mar 24, 2014 at 3:11 PM
Hi,

I would like to import the regression test cases to the TFS 2012.
I've specify the excel workbook - as an example of the Test Case Migrator Plus.
Also loaded an existing setting file - almost the same as an example of the Test Case Migrator Plus.
When I want to use Links mapping session I choose Field containing unique... as Test Case Source ID and Test Case is 'Related to' - Related test case source id.
When I click on save and migrate I recieve the error:
Action - Migrate Work Item - Input string was not in a correct format
Action - Process Links - Pbject reference not set to an instance of an object
Action - Publish report - no workitels are migrated

Can somebody help me to solve this problem?
Thank you in advance,
