Import new Test Suite or Test Plan linked to existing Test Cases to RQM using the RQM Excel importer
One answer

If you check the document, you should notice that you need to use the LinkExisting() modifier to link any existing artifacts.

So your last line should be: testsuite.testcase=LinkExisting("urn:com.ibm.rqm:testcase:"&L2)

Thanks Donald , i tried the solution that you say using the LinkExisting , but in the wiki document says that link existing only works on master/child artifacts , and also when i used it only imports one existing Test Case to the new Test Plan or Test Suite.

I believe it's always "update", not "add". The error that you showed appears irrelevant, as it says "Test Case 55" does not exist. If you construct a resource URI with "urn:com.ibm.rqm:testcase:55" at the end, can you link to the actual test artifact?
