• What is the cause and solution for SAP error message /AIF/VMAP_MESSAGES027 - Database table type is both; select one type ?

  The SAP error message /AIF/VMAP_MESSAGES027 indicates that there is a conflict in the configuration of a database table type in the Application Interface Framework (AIF). Specifically, it suggests that a database table has been defined as both a "standard" and "custom" type, which is not allowed. 
  Cause:
  This error typically arises from one of the following scenarios:
  
  Configuration Conflict: The same database table has been configured in a way that it is recognized as both a standard table and a custom table in the AIF settings.
  Incorrect Mapping: When mapping interfaces or data structures, if a table is mistakenly assigned multiple types, this error can occur.
  Data Model Issues: If there are inconsistencies in the data model definitions, such as duplicate entries or incorrect settings, it can lead to this error.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Configuration:
  
  Go to the AIF configuration settings and review the definitions of the database tables involved.
  Ensure that each table is defined only once and is assigned a single type (either standard or custom).
  
  
  
  Review Mappings:
  
  Check the mappings for the interfaces that are using the conflicting table.
  Make sure that the mappings do not reference the same table with different types.
  
  
  
  Adjust Data Model:
  
  If you have custom tables, ensure that they are correctly defined and do not overlap with standard tables.
  If necessary, modify the data model to eliminate any conflicts.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs.
  Use transaction codes like /AIF/IFMON to monitor the interfaces and check for any remaining issues.
