• What is the cause and solution for SAP error message FKK_EBS152 - The data string in line &1 of IDoc &2 could not be converted ?

  The SAP error message FKK_EBS152 indicates that there is an issue with the conversion of a data string in a specific line of an IDoc (Intermediate Document). This error typically occurs during the processing of electronic bank statements or similar financial documents when the system encounters data that it cannot interpret or convert properly.
  Cause:
  The error can be caused by several factors, including:
  
  
  Data Format Issues: The data in the IDoc may not conform to the expected format. For example, numeric fields may contain non-numeric characters, or date fields may be in an incorrect format.
  
  
  Character Encoding Problems: If the IDoc contains special characters or is encoded in a way that the SAP system does not recognize, it can lead to conversion errors.
  
  
  Field Length Exceeded: The data in the IDoc may exceed the defined length for a particular field in the SAP system.
  
  
  Incorrect Mapping: If the IDoc structure does not match the expected structure in the SAP system, it can lead to conversion issues.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the IDoc Data: Review the specific line mentioned in the error message (line &1 of IDoc &2) to identify any anomalies in the data. Look for incorrect formats, unexpected characters, or data that exceeds field lengths.
  
  
  Validate Data Formats: Ensure that the data in the IDoc adheres to the expected formats for each field. For example, ensure that numeric fields contain only numbers and that date fields are in the correct format.
  
  
  Review IDoc Mapping: Check the mapping of the IDoc to ensure that it aligns with the expected structure in the SAP system. If there are discrepancies, you may need to adjust the mapping or the IDoc structure.
  
  
  Character Encoding: If you suspect character encoding issues, ensure that the IDoc is being sent and processed with the correct encoding (e.g., UTF-8).
  
  
  Consult SAP Documentation: Refer to SAP documentation or notes related to IDoc processing and the specific error message for additional guidance.
  
  
  Debugging: If you have access to the SAP system, you can use transaction codes like WE02 or WE19 to analyze the IDoc and debug the issue further.
