Dear Community,
I've been tring to create a calculation field following all the tips I could find on this forum but still encounters the same error.
I want to calculate the duration of an opportunity.
I've created a field in my opportuntiy type Full number and calculated. He is the rule i want to display (sorry for the french).
I always have the same error telling me that the "actualclosedate" can't be used with the function. But it seems that I do as explained everywhere.
As anyone else encountered the same issue? How did you solved it ?
Thanks for the help
best regards,
Charlotte
