In case indicators have been used, their representativity, robustness and sensitivity should be described in the background documents To RBMPs or background documents Member States should either: 1. Upload a copy of the document to WISE, (guidance on the naming of files is included in the Reportnet Guide (see Annex ); or 2. Include a clear reference document and section to the document stored on the Member States server.
