Targets for common result indicators shall be set in function of the data reported for common output indicators. In accordance with the EC Guidance document on Monitoring and Evaluation based on the Commission Implementing Regulation (EU) No 288/2014 which includes the model for operational programmes (see table 4), it is not possible to set a target for a common result indicator without choosing a common output indicator as reference (this in SFC means that the field is mandatory).
Alternatively, result indicators can be specified as "programme-specific indicators", in order, for example, to link to more than one common output indicator. In that case the field on common output indicators used as basis is not obligatory.
