  The SAP error message CR171, which states "Enter conversion factors," typically occurs in the context of creating or maintaining a material master record, particularly when dealing with units of measure (UoM) in the material management module. This error indicates that the system requires conversion factors to be defined for the different units of measure associated with a material.
  Cause:
  The error arises when:
  
  You are trying to create or modify a material master record that involves multiple units of measure.
  The conversion factors between these units of measure have not been defined in the system.
  The system requires these conversion factors to understand how to convert quantities between different units of measure.
  
  Solution:
  To resolve the CR171 error, you need to enter the conversion factors for the relevant units of measure. Here are the steps to do this:
  
  
  Access Material Master:
  
  Go to the transaction code MM02 (Change Material) or MM01 (Create Material) depending on your requirement.
  
  
  
  Select the Appropriate Views:

  In the relevant view, look for the section where you can define units of measure. This is usually found under the "Units of Measure" tab.
  
  
  
  Enter Conversion Factors:
  
  For each unit of measure you want to use, enter the conversion factor that relates it to the base unit of measure. For example, if your base unit is "KG" and you want to add "GRAM," you would enter a conversion factor of 1000 (since 1 KG = 1000 GRAM).
  
  
  
  Save Changes:
  
  After entering the necessary conversion factors, save your changes.
