# Manage Dimensions and Time Frames

:lock: KPI.**Edit**

## Overview

This operation is used to modify the KPI's dimensions and time frames, i.e, the scope and time variations of the specific KPI.

## Setup

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

## Preconditions

* The KPI exists and it is Active.

## Sequence of Steps

### Step 1: Manage Dimensions

1. Add or remove the desired **KPI** dimensions by using the + and the remove buttons.
2. For each added dimension, provide the following details:
    * **Value Type** - Whether the KPI calculation will return a single value or data series.
    * **Source** - The source of the KPI for calculated KPIs. If the selected source is *Business Rule*, select a Rule from the available options. If the selected source is *Operational Data Store*, *Data Warehouse* or *Cubes*, enter the **Source Command**.
3. Select **Next** to define the **KPI** time frames.

!!! info
	The main objective of the BI Cards functionality is to provide aggregated measures for dashboards visualizations. The *Data Group* functionality is not used for the calculations, therefore the displayed values are not dependent on individual user's *Data Group* permissions.

!!! info
	The calculation of the BI Cards values are mainly done using pre-aggregated data from the Data Warehouse (DWH) or from the Operational Data Store (ODS) database. Each value is calculated by executing a direct query to the data. Please be aware that a poorly created query will impact DWH or ODS performance. Each created query must be tuned in order to guarantee optimal performance.
