• What is the cause and solution for SAP error message RTC_COMM039 - Line &1: Low value cannot be empty if high value exists ?

  The SAP error message RTC_COMM039, which states "Line &1: Low value cannot be empty if high value exists," typically occurs in the context of data entry or configuration in SAP, particularly when dealing with ranges or intervals in fields that require both a low and high value.
  Cause:
  This error arises when a user attempts to enter a range of values where the high value is specified, but the corresponding low value is left empty. In many scenarios, such as pricing conditions, tax calculations, or other configuration settings, both a low and high value are required to define a valid range. If the high value is present without a corresponding low value, the system cannot interpret the range correctly, leading to this error.
  Solution:
  To resolve this error, you should ensure that both the low and high values are filled in correctly. Here are the steps to follow:
  
  
  Identify the Field: Check the specific line number indicated in the error message (Line &1) to locate the field causing the issue.
  
  
  Enter Low Value: If a high value is already present, make sure to enter a corresponding low value. This could be a minimum value that logically corresponds to the high value.
  
  
  Validation: After entering the low value, validate the data entry to ensure that it meets any additional criteria or constraints that may be in place.
  
  
  Save Changes: Once both values are entered correctly, save your changes and check if the error persists.
  
  
  Related Information:
  
  Data Entry Guidelines: Always refer to the specific guidelines for the module you are working in (e.g., Sales and Distribution, Material Management) to understand the requirements for entering ranges.

  By ensuring that both low and high values are appropriately filled, you should be able to resolve the RTC_COMM039 error and proceed with your tasks in SAP.
