Attachment in stepresult in Executionresult using RQMcopyuti
One answer
You can use the RQM Reportable REST API to upload the attachment resource (note, https://jazz.net/wiki/bin/view/Main/RqmApi#ResourcesFootnote6) and put the attachment URL in the qm:executionresult/executionresult:stepResults/er:stepResult/er:stepAttachment property (see https://jazz.net/products/rational-quality-manager/api-doc-5.0.1/schemas/executionresult_xsd/elements/stepResult.html#a20).
