• What is the cause and solution for SAP error message FSC1021 - No external transaction determined for internal transaction &1/&2 ?

  The SAP error message FSC1021, which states "No external transaction determined for internal transaction &1/&2," typically occurs in the context of financial transactions, particularly when dealing with the integration of internal and external transactions in SAP Financial Supply Chain Management (FSCM) or similar modules.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Missing Configuration: The internal transaction code (ITC) does not have a corresponding external transaction code (ETC) defined in the system. This can happen if the mapping between internal and external transactions has not been set up correctly.
  
  
  Incorrect Transaction Mapping: The mapping between internal and external transactions may be incorrect or incomplete. This can occur if changes were made to transaction codes or if new transactions were introduced without proper mapping.
  
  
  Data Issues: There may be issues with the data being processed, such as missing or incorrect entries in the relevant tables that link internal and external transactions.
  
  
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the external transaction, leading to this error.
  
  
  Solution:
  To resolve the FSC1021 error, you can take the following steps:
  
  
  Check Configuration:
  
  Go to the configuration settings for transaction mapping in your SAP system. This is usually found in the customizing settings under Financial Supply Chain Management.
  Ensure that there is a valid mapping between the internal transaction code (ITC) and the external transaction code (ETC).
  
  
  
  Maintain Transaction Mapping:
  
  If the mapping is missing, you will need to create it. This can typically be done in the transaction code SPRO, navigating to the relevant section for transaction mapping.
  Ensure that all necessary internal transactions have corresponding external transactions defined.
  
  
  
  Review Data:
  
  Check the relevant tables (such as T030 or similar) to ensure that the data is correct and complete.
  Look for any inconsistencies or missing entries that could be causing the issue.
  
  
  
  User Authorizations:
  
  Verify that the user encountering the error has the necessary authorizations to access the external transaction. This can be checked in the user roles and profiles.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test transaction to ensure that the error no longer occurs.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with the relevant transaction codes used in your SAP system for financial transactions and mapping.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
