An issue can be linked to any number of requirements. By means of these links you can map e.g. dependencies or relationships between issues and other data. The semantics of a link is not default. Therefore it is appropriate to define the semantics of links between issues and other data in your project or in your organization.
Links between issues and other data can be created and deleted in the Forms Editor of issues. For this drag the desired data (e.g. a requirement) via drag & drop into the field "Concerned items". By clicking on the unlink button you can delete the link.
