Hello,

 

in the page " set goals" in the performance management mdule is there a way in order to put in read only the field "weight" considering the category.

In details we have some goals with the category "economici" and some goals with category "sostenibilità" and " infortuni"; we would like to put in read only the weight only for that goals with category "economici" with an EL. Is this possibile??

 

NB: you can find an attachment with the screenshot of the page that we want to customize in document section.
