• What is the cause and solution for SAP error message JIT00101 - Reference number &2 from type &1 is only permitted at header level ?

  The SAP error message JIT00101 indicates that a reference number of a specific type is being used incorrectly in the context of a document or transaction. This error typically arises in the context of Just-In-Time (JIT) delivery processes, where certain reference numbers are expected to be associated only with the header level of a document, rather than at the item level.
  Cause:
  The error occurs when:
  
  A reference number (e.g., a delivery note, order number, etc.) is being assigned to an item level in a JIT delivery or related transaction, but the system only allows this reference number to be associated with the header level.
  The configuration or settings in the JIT process may not be aligned with the data being entered.
  
  Solution:
  To resolve the JIT00101 error, you can take the following steps:
  
  
  Check the Reference Number: Ensure that the reference number you are trying to use is indeed meant for the header level. Review the documentation or configuration for the specific reference type to confirm its intended use.
  
  
  Adjust Data Entry: If you are entering the reference number at the item level, change your entry to the header level. This may involve navigating to the appropriate section of the transaction where header-level data can be entered.
  
  
  Review Configuration: If you believe the reference number should be allowed at the item level, review the configuration settings in the JIT process. This may involve checking the customizing settings in SPRO (SAP Project Reference Object) to see if the reference number type can be modified to allow item-level entries.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details about the reference number types and their allowed levels. This can provide insights into how to properly configure or use these reference numbers.
  
  
  Contact Support: If the issue persists and you cannot determine the cause or solution, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes related to JIT processes, such as JIT delivery creation or monitoring transactions.
  SAP Notes: Check for any SAP Notes related to JIT processes and error messages, as they may provide additional context or solutions.
  User Exits and BAdIs: If customization is required, consider looking into user exits or Business Add-Ins (BAdIs) that may allow for more flexible handling of reference numbers.
  
  By following these steps, you should be able to address the JIT00101 error effectively.
