  The SAP error message FCOM_MASTERDATA102 indicates that there is an issue with the interface you are trying to create or modify in the Financial Accounting (FI) module. Specifically, the error states that you cannot enter an empty interface or an interface that already exists. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Empty Interface: You may be attempting to create a new interface without providing the necessary details or parameters. An empty interface does not have the required data to be processed.
  Duplicate Interface: The interface you are trying to create already exists in the system. SAP does not allow the creation of duplicate entries for interfaces.
  
  Solutions:
  
  
  Check for Existing Interfaces:
  
  Before creating a new interface, check if the interface you are trying to create already exists. You can do this by navigating to the relevant transaction code (e.g., FSP0 for Financial Statement Versions) and searching for the interface name.
  If it exists, you may need to modify the existing interface instead of creating a new one.
  
  
  
  Provide Required Data:
  
  If you are creating a new interface, ensure that all required fields are filled out correctly. Review the input fields and make sure that none are left empty.
  Validate that the data you are entering meets the necessary criteria for the interface.
  
  
  
  Use Transaction Codes:
  
  Use the appropriate transaction codes to manage interfaces. For example, if you are working with financial statement versions, use OB58 to create or modify them.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help files for specific guidelines on creating interfaces in the context you are working in. This can provide insights into required fields and data formats.
  
  
  
  Check Authorization:
  
  Ensure that you have the necessary authorizations to create or modify interfaces in the system. Lack of proper permissions can sometimes lead to unexpected errors.
