  • The database has a limitation of length for each field. Please note that this limit may differ among different fields.
  • The limit is set in the database and any change on it needs to be submitted as an enhancement request.


  • Check the Connector Workbook for the length limitation of each field. 2326249 points to where the Data Dictionary can be downloaded. It can be used to cross reference total length in the database in bytes.
  • Please see 2571786 which explains field lengths.
  • Fixing the data in the file will keep the connector job to generate the exception, the fix may have to be performed in BizX if it's a Connector that utilizes data from that system.
  • Please see example below: CPNT_TITLE

Note: Not every single character is proportioned to 1 byte. There are many characters that are 3 bytes in different languages. In case if the error is still received, validate how many bytes each character is and update the value in the input file to adhere to the appropriate length.
