• What is the cause and solution for SAP error message SADL_GW_ATC_VOCAN002 - &1: Stringlength &2 exceeded ?

  The SAP error message SADL_GW_ATC_VOCAN002 with the description "String length &2 exceeded" typically occurs in the context of the SAP Gateway and the ABAP programming environment when a string input exceeds the defined length for a particular field or parameter.
  Cause:
  
  Input Length Exceeded: The error is triggered when a string being processed exceeds the maximum length defined for that field in the data model or database table.
  Data Model Constraints: The data model may have constraints that limit the length of certain fields, and if the input data exceeds these constraints, the error will occur.
  Incorrect Data Mapping: If there is a mismatch between the data being sent from the frontend (like an SAP Fiori app) and the backend data model, it can lead to this error.
  
  Solution:
  
  Check Field Lengths: Review the data model and identify the field that is causing the issue. Check the maximum length defined for that field and ensure that the input data does not exceed this length.
  Data Validation: Implement validation checks in your application to ensure that the data being sent to the backend does not exceed the allowed lengths. This can be done on the frontend before making the API call.
  Adjust Data Model: If the business requirement allows, consider adjusting the data model to accommodate longer strings. This may involve changing the field length in the database or the data structure in the ABAP program.
  Error Handling: Implement error handling in your application to catch this error and provide user-friendly feedback, guiding users to correct their input.
