• What is the cause and solution for SAP error message /SAPAPO/MC01_ECV009 - Flat parameter (&1) requested for multi-line select-option ?

  The SAP error message /SAPAPO/MC01_ECV009 typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a flat parameter is requested for a multi-line select-option. This error indicates that the system is expecting a single value for a parameter, but a multi-line selection (multiple values) has been provided instead.
  Cause:
  The primary cause of this error is that the system is trying to process a selection option that is not compatible with the expected input format. Specifically, it occurs when a flat parameter (which expects a single value) is being supplied with multiple values from a selection option.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Input Parameters: Review the input parameters you are providing to the transaction or report. Ensure that you are not passing multiple values for a parameter that only accepts a single value.
  
  
  Modify the Selection Criteria: If you need to filter by multiple values, consider using a different parameter that supports multiple selections or adjust your selection criteria to use a single value.
  
  
  Review the Documentation: Check the documentation for the specific transaction or report you are using to understand the expected input format for each parameter.
  
  
  Use a Different Approach: If the logic of your process requires multiple values, you may need to implement a different approach, such as looping through the values and processing them one at a time.
  
  
  Consult with SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for further assistance.
