Field help (CCNUSRRNW) 

This field contains the reference of the concession's grantor.
This is not mandatory; if no grantor is entered, the processing will concern all the renewal operations (validation or cancellation) of the concessions assigned to the specified site.
It can be entered and will then be used to filter on the renewing assets. If it is not entered, it is systematically loaded if a concession or a renewing asset is entered.
