• What is the cause and solution for SAP error message RSSDA108 - Field &1: SAP HANA type BIGINT with ConvExit SNUMC must have length 20 ?

  The SAP error message RSSDA108 indicates that there is an issue with the data type and length of a field in your SAP HANA database. Specifically, it refers to a field that is defined as a BIGINT type but is expected to have a length of 20 when using the conversion exit SNUMC (which is typically used for numeric fields).
  Cause:
  
  Data Type Mismatch: The field in question is defined as a BIGINT in SAP HANA, but the conversion exit SNUMC expects a character string of length 20. This mismatch can occur if the data being processed does not conform to the expected format or length.
  Incorrect Field Definition: The field may not be defined correctly in the ABAP Dictionary or in the data model, leading to inconsistencies between the expected and actual data types.
  Data Input Issues: If the data being input into this field exceeds the expected length or is not formatted correctly, it can trigger this error.
  
  Solution:
  
  Check Field Definition: Review the field definition in the ABAP Dictionary (SE11) to ensure that it is correctly defined as a BIGINT and that it is using the appropriate conversion exit.
  Adjust Data Length: If the field is expected to hold a numeric value that can be represented as a BIGINT, ensure that the data being input does not exceed the length of 20 characters. If necessary, adjust the data being processed to fit within this limit.
  Modify Conversion Exit: If the conversion exit SNUMC is not appropriate for this field, consider using a different conversion exit that matches the data type and length requirements.
  Data Validation: Implement validation checks in your application logic to ensure that any data being written to this field adheres to the expected format and length.
  
  Related Information:
  
  BIGINT Data Type: In SAP HANA, the BIGINT data type is used to store large integer values. It can hold values from -2^63 to 2^63-1.
  Conversion Exits: Conversion exits in SAP are used to convert data between different formats. SNUMC is typically used for numeric character strings, and it may not be suitable for all numeric types.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling BIGINT fields and conversion exits.
  
  If the issue persists after following these steps, consider reaching out to SAP support for further assistance, as they may have more specific insights based on your system configuration and version.
