• What is the cause and solution for SAP error message FMCA_ISR_EN519 - A key field has to be set as a read only input field ?

  The SAP error message FMCA_ISR_EN519 indicates that a key field in a form or application is not set as read-only when it should be. This typically occurs in the context of Interactive Forms or Web Dynpro applications where certain fields are expected to be immutable (read-only) to ensure data integrity and consistency.
  Cause:
  
  Field Configuration: The field in question is a key field that uniquely identifies a record in the database. It should not be editable by the user to prevent accidental changes that could lead to data integrity issues.
  Form Design: The form or application may not have been designed correctly, leading to key fields being editable when they should be read-only.
  User Permissions: In some cases, user roles and permissions may allow editing of fields that should be read-only.
  
  Solution:
  
  
  Modify Field Properties:
  
  Access the form or application in the SAP development environment (e.g., Adobe LiveCycle Designer for Interactive Forms).
  Locate the key field that is causing the error.
  Set the field's properties to "Read-Only" to ensure that users cannot edit it.
  
  
  
  Check Application Logic:
  
  Review the application logic to ensure that key fields are correctly defined and handled.
  Ensure that the logic that populates these fields does not allow for user input.
  
  
  
  User Role Review:
  
  Check the user roles and permissions to ensure that users do not have the ability to edit key fields.
  Adjust roles as necessary to restrict access to these fields.
  
  
  
  Testing:
  
  After making changes, test the form or application to ensure that the error no longer occurs and that the key fields behave as expected.
