• What is the cause and solution for SAP error message FDT_CORE414 - Table &1 has a key field of type string ?

  The SAP error message FDT_CORE414 indicates that there is an issue with a table definition in the context of the Field Data Tool (FDT). Specifically, the error states that the table &1 has a key field of type string, which is not supported.
  Cause:
  The root cause of this error is that the table in question has a key field defined with a data type that is not compatible with the requirements of the FDT. In SAP, key fields are typically expected to be of certain types (like integer, character, etc.), and a key field defined as a string type is not valid in this context.
  Solution:
  To resolve this error, you will need to modify the table definition to ensure that the key field is of a supported data type. Here are the steps you can take:
  
  
  Identify the Table: Determine which table is causing the error by checking the error message for the specific table name that replaces &1.
  
  
  Check Table Definition: Go to the Data Dictionary (transaction SE11) and look up the table. Review the key fields and their data types.
  
  
  Modify Key Field Type:
  
  If the key field is currently defined as a string type, change it to a supported type (e.g., CHAR, NUMC, etc.).
  Ensure that the new data type is appropriate for the data that will be stored in that field.
  
  
  
  Activate the Table: After making the necessary changes, activate the table to apply the modifications.
  
  
  Test the Changes: After activation, test the functionality that was previously causing the error to ensure that the issue has been resolved.
