I'm using a rule (insertaction) to insert a value into a calculated item.
It works but I would like to be sure to follow the right way when I set the calculated item in the crf.
The 2 columns I want to focus are the RESPONSE_TYPE and the RESPONSE_VALUES_OR_CALCULATIONS.
In the RESPONSE_TYPE I select 'calculation' because I want to prevent any modification on it.
The RESPONSE_VALUES_OR_CALCULATIONS column should be left empty because I don't want to calculate/derive the value
from another item in the crf but, since it is no possible, in this column I put its own ITEM_NAME.
What I would like to be sure is:
is it right to put the ITEM_NAME in the RESPONSE_VALUES_OR_CALCULATIONS or it could cause errors?
Is there is a better way to do that? Suggestions?
Many thanks in advance.
