• What is the cause and solution for SAP error message EG399 - You have not entered 1 for primary or secondary voltage ?

  The SAP error message EG399, which states "You have not entered 1 for primary or secondary voltage," typically occurs in the context of electrical engineering or utility management modules within SAP, particularly when dealing with equipment or functional locations that require voltage specifications.
  Cause:
  This error usually arises when:
  
  Missing Voltage Data: The system expects a value (usually '1' for primary or secondary voltage) to be entered in the relevant fields, but these fields are left blank or filled incorrectly.
  Configuration Issues: The equipment or functional location may not be properly configured to handle voltage specifications.
  Data Entry Errors: Users may have overlooked entering the required voltage data during the creation or modification of equipment or functional location records.
  
  Solution:
  To resolve the EG399 error, you can take the following steps:
  
  
  Check Equipment/Functional Location Data:
  
  Navigate to the equipment or functional location that triggered the error.
  Ensure that the primary and secondary voltage fields are filled in correctly. Enter '1' or the appropriate voltage value as required.
  
  
  
  Review Configuration Settings:
  
  If you are an administrator or have access to configuration settings, check the configuration for the relevant module (e.g., PM, CS, or other relevant modules).
  Ensure that the voltage fields are set up correctly in the system.
  
  
  
  Data Entry Validation:
  
  If you are entering data manually, double-check your entries to ensure that you are not missing any required fields.
  If using a template or mass upload, ensure that the template includes the necessary voltage fields and that they are populated correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or user manuals specific to your version and module for guidance on entering voltage data.
  
  
  
  Seek Help from IT Support:
  
  If the issue persists after checking the above, consider reaching out to your IT support team or SAP consultant for further assistance. They may need to investigate system settings or user permissions.
  
  
  
  Related Information:
  
  SAP Modules: This error is often encountered in modules related to Plant Maintenance (PM), Customer Service (CS), or other industry-specific solutions that deal with equipment management.
  User Roles: Ensure that users have the appropriate roles and permissions to enter or modify equipment data.
  Training: Providing training for users on how to correctly enter and manage equipment data can help prevent similar errors in the future.
  
  By following these steps, you should be able to resolve the EG399 error and ensure that the necessary voltage data is correctly entered into the SAP system.
