  Solution:
  
  Check Input Values: Review the data you are trying to upload and ensure that all relevant fields contain positive values. Correct any entries that are zero or negative.
  Data Validation: Implement data validation checks before running the LSMW process to ensure that all values meet the required criteria.
  Review Mapping: If you are using a mapping file or transformation rules, check to ensure that the data is being transformed correctly and that no negative or zero values are being generated.
  Debugging: If the issue persists, consider debugging the LSMW process to identify where the invalid value is being introduced. This may involve checking the source data and the transformation logic.
  Consult Documentation: Refer to the SAP documentation for LSMW to understand the specific requirements for the fields you are working with.
