Is there a way to customize intake forms when filling out a customer complaint?

Answer:
According to the requirement 8.2.2 Complaint handling, following data are necessary for each customer complaint:
-Date of receiving the complaint
-Complaint description
-Who received a complaint
-Who reviewed it – investigated it – is it reasonable or unreasonable
-Suggestion for complaint treatment
-Who approved suggestion
-Execution deadline
-Responsible for execution
-Is there any corrective or preventive action initiated

It can be done in table form. When taking the customer description, be sure to take the Lot number and to how many pieces of the medical device this compliant referred to. When you create a form that will cover all of these elements, you must ensure that such a form is available to anyone who needs it whenever they need it.
