Smart SAP Assistant

• What is the cause and solution for SAP error message CNV20551556 - &1: Total length = &2 exceeds field length = &3 ?

  The SAP error message CNV20551556 typically indicates that there is a data length issue during a data migration or conversion process. Specifically, it means that the total length of the data being processed exceeds the maximum allowed length for a specific field in the target database or structure.
  Cause:
  
  
  Data Length Exceeding Field Limit: The primary cause of this error is that the data being imported or processed has a total length that exceeds the defined length of the target field. This can happen if:
  
  The source data contains longer strings than the target field can accommodate.
  There are concatenated fields or multiple values being combined into a single field that exceed the length limit.
  
  
  
  Incorrect Mapping: If the mapping between source and target fields is not correctly defined, it can lead to this error. For example, if a source field is mapped to a target field with a smaller length.
  
  
  Data Quality Issues: Sometimes, the source data may have unexpected characters or formatting that increases its length.
  
  
  Solution:
  
  
  Review Data Lengths: Check the lengths of the source data and compare them with the target field definitions. Ensure that the data being migrated fits within the constraints of the target fields.
  
  
  Adjust Field Lengths: If possible, consider increasing the length of the target field in the database to accommodate the incoming data. This may involve modifying the database schema.
  
  
  Data Transformation: Implement data transformation rules to truncate or modify the data before it is loaded into the target field. This can include:
  
  Truncating strings to fit the target length.
  Splitting data into multiple fields if necessary.
  
  
  
  Mapping Review: Revisit the mapping configuration to ensure that each source field is correctly mapped to a target field with an appropriate length.
  
  
  Data Cleansing: Perform data cleansing on the source data to remove any unnecessary characters or formatting that may be contributing to the length issue.
  
  
  Testing: After making adjustments, conduct tests to ensure that the data migration or conversion process works without triggering the error.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary) to check field definitions or SE80 (Object Navigator) to review the data model.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on data migration issues.
  Documentation: Review SAP documentation related to data migration tools (like SAP S/4HANA Migration Cockpit) for best practices and guidelines.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the CNV20551556 error effectively.
