• What is the cause and solution for SAP error message ID518 - INTTAB contains more than one transaction in BDCDATAEXP mode ?

  The SAP error message ID518, which states "INTTAB contains more than one transaction in BDCDATAEXP mode," typically occurs during the processing of batch input sessions. This error indicates that the internal table (INTTAB) used for batch input contains multiple transactions, which is not allowed in the BDCDATAEXP mode.
  Cause:
  The error is caused by the following scenarios:
  
  Multiple Transactions: The batch input session is trying to process multiple transactions at once, but the BDCDATAEXP mode expects only one transaction to be processed at a time.
  Incorrect Configuration: The configuration of the batch input session may not be set up correctly, leading to multiple transactions being included in the same session.
  Data Preparation Issues: The data being fed into the batch input session may have been incorrectly prepared, resulting in multiple entries being included in the same batch.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Batch Input Session:
  
  Review the batch input session to ensure that it contains only one transaction. If there are multiple transactions, separate them into different sessions.
  
  
  
  Modify the Data Preparation:
  
  Ensure that the data being prepared for the batch input is correctly formatted and that each transaction is isolated. This may involve adjusting the data extraction or transformation process to ensure that only one transaction is included per batch input session.
  
  
  
  Review Configuration Settings:
  
  Check the configuration settings for the batch input processing. Ensure that the settings are appropriate for the type of transactions being processed.
  
  
  
  Use Correct Function Modules:
  
  If you are using custom code to create the batch input session, ensure that you are using the correct function modules and that they are being called in the right sequence.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the batch input program to identify where the multiple transactions are being introduced. This may involve checking the logic that populates the INTTAB.
  
  
  
  Related Information:
  
  BDCDATA Structure: The BDCDATA structure is used in batch input processing to hold the data for each screen field. Each entry in this structure corresponds to a field on the screen of the transaction being processed.
  Batch Input Sessions: Batch input sessions are used in SAP to automate data entry processes. They allow for the processing of large volumes of data by simulating user input.
  Transaction Codes: Familiarize yourself with transaction codes related to batch input processing, such as SM35 (to manage batch input sessions) and SE37 (to view function modules).
  
  By following these steps and understanding the underlying causes, you should be able to resolve the ID518 error and successfully process your batch input sessions.
