If you entered by mistake a Common indicator for a Priority in the Summary table of Appendix 1 and you try to remove it, the system will return an error message:

Appendix 1 only accepts Common indicators: the Indicator Code list contains all Common Indicator codes (and their description), Output and Result, already used in Tables 2 and 3, for the Priority, Fund, Category of Region, Specific Objective combination.

If you do not have a Common indicator but a Programme specific indicator, then you have to leave the indicator field empty and set the SCO to non-applicable at the end of the row.
