  The SAP error message /SAPAPO/DC_MSG166 indicates that there is an issue with the input of values in a certain context, typically related to planning or data entry in SAP Advanced Planning and Optimization (APO). The specific message "End value can only be entered with a start value" suggests that the system expects a start value to be defined before an end value can be entered.
  Cause:
  This error usually occurs in scenarios where a range of values is expected, such as:

  Review Configuration: If you are working with a custom configuration or a specific planning scenario, review the settings to ensure that the start and end values are correctly configured.
  
  
  Consult Documentation: Refer to the SAP documentation or help files related to the specific transaction or module you are working with. This can provide insights into the expected input and any constraints.
