# Manage Parameters

:lock: Product.**Edit**

## Overview

This operation is used to set and manage Product parameters.

## Setup

No specific setup is required other than to meet the precondition of the transaction.

## Preconditions

* The Product (Version) exists in the system and it is not Terminated.

## Sequence of Steps

### Step 1: Manage Parameters (Versioned Data)

1. Add as many parameters as desired, providing for each line:
      * The **Parameter** name.
      * The  **Parameter** type: *Specification* or *Characteristic*.  A *Specification* can be used for SPC integration and it can have defined a lower specification value, a target value and an upper specification value. A *Characteristic* is a constant value that is associated with the **Product**.
      * The value, only for parameters of type *Characteristic*.
      * Optionally, the Step, for parameters of type *Specification* only.
      * Optionally, the lower specification value, for parameters of type *Specification* only.
      * Optionally, the target specification value, for parameters of type *Specification* only.
      * Optionally, the upper specification value, for parameters of type *Specification* only.
      * Optionally, the Reporting Type (the values are taken from the lookup table *ProductParameterReportingType*).
      * Optionally, a Reporting Information (free text).
2. Select **Update** to complete the operation.
