manual maintenance of the key flag was activated, you MUST store the
key fields together at the beginning.

• What is the cause and solution for SAP error message MC705 - Key fields are not together at the beginning of the view ?

  The SAP error message MC705 ("Key fields are not together at the beginning of the view") typically occurs when you are working with a database view in SAP, particularly in the context of the Data Dictionary (DDIC). This error indicates that the key fields of the view are not defined consecutively at the beginning of the view's structure, which is a requirement for database views in SAP.
  Cause:
  
  Key Field Arrangement: In a database view, the key fields must be defined together at the start of the view. If they are scattered throughout the structure, SAP will throw this error.
  View Definition: The way the view is defined in the ABAP Dictionary may not adhere to the required structure for key fields.
  
  Solution:
  To resolve the MC705 error, you need to ensure that all key fields are defined consecutively at the beginning of the view. Here are the steps to fix the issue:
  
  Open the View in SE11: Go to transaction SE11 (Data Dictionary) and enter the name of the view that is causing the error.
  Check Key Fields: In the view definition, check the list of fields and identify the key fields.
  Rearrange Key Fields: Move the key fields so that they are the first fields in the view definition. Ensure that they are listed consecutively.
  Save and Activate: After making the necessary changes, save the view and activate it.
  Test the View: After activation, test the view to ensure that it works correctly without throwing the error.
