• What is the cause and solution for SAP error message C1128 - Too many decimal places ?

  The SAP error message C1128 "Too many decimal places" typically occurs when a user attempts to enter a numeric value that exceeds the allowed number of decimal places defined for a particular field in the SAP system. This can happen in various transactions or reports where numeric input is required, such as in financial documents, material master records, or other data entry forms.
  Cause:
  
  Field Configuration: The field in which the value is being entered has a predefined limit on the number of decimal places. For example, if a field is configured to accept only two decimal places, entering a value like 123.456 would trigger this error.

  Check Field Configuration: Review the field settings in the relevant transaction or table to determine the allowed number of decimal places. This can often be found in the field documentation or by consulting with a system administrator.
  Adjust Input Value: Modify the input value to conform to the allowed number of decimal places. For example, if the field allows only two decimal places, round or truncate the value accordingly (e.g., change 123.456 to 123.46).
  Consult Documentation: If you are unsure about the field's configuration, refer to the SAP documentation or help resources for guidance on the specific transaction or module you are working with.
  System Configuration: If you have the necessary permissions, you may consider adjusting the field configuration in the system settings to allow for more decimal places, if appropriate for your business needs. This typically requires access to the SAP Customizing Implementation Guide (IMG).
