  Adjust the Input: If you are using a date picker or input field, make sure to select the entire month rather than a specific day or range.
  
  
  Review Configuration Settings: If you have access to configuration settings, check the fiscal year variant and period settings to ensure they are correctly set up to accept whole months.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific transaction you are working with to understand the expected input format.
