Use the Change Forecast Range dialog box to define the range of calendar period columns you want to display on resource management reports. 
  
 
	  
		The forecast range determines the number of calendar period columns and the time frame each calendar period column represents. 
		
 
		| Field | Description | 
|---|
 
		   
		  | Scale | Select whether you want the calendar period columns to represent days, weeks, or months. | 
 
		   
		  | Duration | Select the number of calendar period columns to include for the forecast range. Each calendar period column contains planning data for one day, week, or month, based on what you selected in the 
			 Scale field. For example, if you select 
			 Weeks in 
			 Scale and select 
			 8 in 
			 Duration, eight columns display. Each column contains planning data for one week. The options available in the 
			 Duration field vary depending on the scale you selected. | 
 
		   
			 | Start Date/Week/Month | Based on what you entered in the 
				Scale field, select the first day, week, or month in the forecast range. Unlike for the forecast range for Resource View, the starting period for a report can be prior to the JTD date. |
