• What is the cause and solution for SAP error message RSSDA107 - Field &1: SAP HANA type INTEGER with ConvExit SNUMC must have length 11 ?

  The SAP error message RSSDA107 indicates that there is a mismatch in the expected length of a field defined in SAP HANA. Specifically, it refers to a field that is expected to be of type INTEGER with a conversion exit (ConvExit) for SNUMC (which is typically used for numeric character strings). The error states that the field must have a length of 11.
  Cause:
  The error is typically caused by one of the following reasons:
  
  Field Length Mismatch: The field in the SAP HANA database is defined as an INTEGER, but the application or data model expects it to be a character string of length 11. This is common when dealing with numeric values that are stored as strings for specific formatting or validation purposes.
  Data Type Conversion Issues: When data is being transferred or transformed between different systems or layers (e.g., from ABAP to HANA), the expected data types and lengths may not match, leading to this error.
  Incorrect Mapping: If the data model or mapping in the SAP application does not correctly align with the database schema, it can lead to this error.
  
  Solution:
  To resolve the RSSDA107 error, you can take the following steps:
  
  
  Check Field Definitions: Verify the field definitions in both the SAP application and the HANA database. Ensure that the field defined as INTEGER in HANA is correctly mapped to a field that can accommodate the expected length of 11 characters.
  
  
  Adjust Data Types: If the field is meant to store numeric values that can exceed the standard INTEGER range, consider changing the data type in HANA to a larger numeric type (e.g., BIGINT) or a character type (e.g., VARCHAR) that can accommodate the length requirement.
  
  
  Review Conversion Exits: If you are using conversion exits (like SNUMC), ensure that they are correctly applied and that the data being processed adheres to the expected format. You may need to adjust the conversion logic to handle the data correctly.
  
  
  Data Validation: Before inserting or updating data in the database, validate the data to ensure it meets the length and type requirements. Implement checks in your application logic to prevent invalid data from being processed.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or ABAP team for specific guidelines on handling data types and conversion exits in your version of SAP.
  
  
  Related Information:
  
  SAP HANA Data Types: Familiarize yourself with the various data types supported by SAP HANA and their characteristics.
  Conversion Exits: Understand how conversion exits work in SAP and how they can be used to format or validate data.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling data type issues.
  
  By following these steps, you should be able to identify the root cause of the RSSDA107 error and implement a suitable solution.
