• What is the cause and solution for SAP error message CP299 - Lower or upper limit of lot size negative ?

  The SAP error message CP299, which states "Lower or upper limit of lot size negative," typically occurs in the context of production planning and control, particularly when dealing with lot sizing in material requirements planning (MRP) or production orders. This error indicates that the defined lot size parameters for a material or production process are incorrectly set, leading to negative values for either the lower or upper limits of the lot size.
  Cause:
  
  Incorrect Lot Size Configuration: The lot size settings in the material master or the production version may have been incorrectly defined, resulting in negative values.
  Negative Values in Master Data: There may be negative values inadvertently entered in the lot size fields in the material master or production version.
  Inconsistent Data: The data in the system may be inconsistent, possibly due to manual entries or data migration issues.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master (transaction code MM03) and check the lot size settings under the MRP view.
  Ensure that the lower and upper limits of the lot size are set to positive values.
  
  
  
  Review Production Version:
  
  If applicable, check the production version (transaction code C202) for the material and ensure that the lot size parameters are correctly defined.
  
  
  
  Adjust Lot Size Parameters:
  
  If you find negative values, correct them to appropriate positive values. For example, set the minimum lot size to 1 or any other positive integer that makes sense for your production process.
  
  
  
  Check for User Exits or BAdIs:
  
  If there are any custom developments or enhancements (like user exits or BAdIs) that might be affecting the lot size calculations, review and adjust them as necessary.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific guidance on lot size settings and best practices.
