• What is the cause and solution for SAP error message CNV_PE793 - &1: Fixed value is too long ?

  The SAP error message CNV_PE793 with the description "Fixed value is too long" typically occurs during data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools. This error indicates that a fixed value being processed exceeds the maximum length allowed for that field in the target system.
  Cause:
  
  Field Length Exceeded: The fixed value being assigned to a field in the target table exceeds the defined length of that field. For example, if a field in the target table is defined to accept a maximum of 10 characters, and the fixed value being assigned is 15 characters, this error will occur.
  Data Mapping Issues: There may be a mismatch in the data mapping configuration where the source data has longer values than the target field can accommodate.
  Configuration Errors: Incorrect configuration in the data migration settings or transformation rules can lead to this error.
  
  Solution:
  
  Check Field Lengths: Review the target table's field definitions to determine the maximum length allowed for the field in question. Ensure that the fixed values being assigned do not exceed this length.
  Adjust Fixed Values: If possible, modify the fixed values to fit within the allowed length. This may involve truncating the values or changing them to shorter alternatives.
  Data Mapping Review: Examine the data mapping configuration to ensure that the source data is correctly mapped to the target fields. Adjust the mapping if necessary to ensure compatibility.
  Transformation Rules: If you are using transformation rules, check them for any logic that might be causing longer values to be assigned than intended. Modify the rules to ensure they produce values that fit within the target field lengths.
  Testing: After making adjustments, perform a test run of the data migration to ensure that the error is resolved and that the data is being processed correctly.
