• What is the cause and solution for SAP error message MC103 - Field & of table & missing from FIELD_MAP ?

  The SAP error message MC103, which states "Field & of table & missing from FIELD_MAP," typically occurs in the context of data extraction or reporting, particularly when working with the Logistics Information System (LIS) or other data-related functionalities in SAP.
  Cause:
  The error indicates that a specific field (denoted by &) from a specified table (also denoted by &) is not defined in the FIELD_MAP. The FIELD_MAP is a configuration that maps fields from the database tables to the data structures used in reporting or extraction processes. This can happen due to several reasons:
  
  Missing Configuration: The field may not have been included in the FIELD_MAP configuration, which is necessary for the data extraction or reporting process.
  Changes in Data Model: If there have been changes to the underlying data model (e.g., new fields added to a table), the FIELD_MAP may not have been updated accordingly.
  Custom Developments: If there are custom developments or enhancements that introduce new fields, these may not be reflected in the standard FIELD_MAP.
  Transport Issues: If the FIELD_MAP configuration was transported from one system to another, it may not have included all necessary fields.
  
  Solution:
  To resolve the MC103 error, you can follow these steps:
  
  
  Check FIELD_MAP Configuration:
  
  Go to the relevant transaction (e.g., MC22 for LIS) to view the FIELD_MAP configuration.
  Verify if the field in question is indeed missing from the FIELD_MAP.
  
  
  
  Add Missing Field:
  
  If the field is missing, you can add it to the FIELD_MAP. This typically requires appropriate authorization and knowledge of the data model.
  Ensure that the field is correctly mapped to the corresponding data structure.
  
  
  
  Review Data Model Changes:
  
  If there have been recent changes to the data model, review those changes to ensure that all necessary fields are accounted for in the FIELD_MAP.
  
  
  
  Check for Custom Developments:
  
  If there are custom developments, ensure that they are properly integrated into the FIELD_MAP.
  
  
  
  Transport Configuration:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included in the transport.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific module you are working with for any additional guidance.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the error is resolved and that data extraction or reporting works as expected.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MC22 (for maintaining FIELD_MAP) and MC93 (for displaying the data structure).
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message MC103.
  Authorization: Ensure you have the necessary authorizations to make changes to the FIELD_MAP and related configurations.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or functional team for further assistance.
