 Using the Display Data Dictionary Field display you can:

  • Use the CHANGE function key to change the field definition. Changes to the field definition must match the criteria described in the section "Creating a new field definition".
    Note that if the field has been successfully changed and a reference field exists then the Reference Field Extended Options screen will be presented for selection of copy options (see section on creating new field definitions for more information).
  • Use the REFERENCES function key to display a list of all the fields which refer to this field for their definition. This function key is only displayed when the current field is referred to by at least one other field.When a referenced field is updated this list is displayed for confirmation that all the referencing fields and the current field should be updated.
  • Use the DELETE function key to delete the field definition. After the delete key has been used it will be necessary to confirm the delete request by entering YES on This screen:

 
  DC@P100103             Delete Data Dictionary Field                   
                                                                       
 Field name  . . . : XXXXXXXXXX                                        
 Description . . . : XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                                                                       
                                                                       
       Confirm this field is to be deleted.                            
                                                                       
                                                                       
       Delete this field . . . ___   YES, NO                           
                                                                       
                                                                       
 Fnn=Help  Fnn=Exit  Fnn=Cancel  Fnn=Messages                          
 

If a Web visual component exists for the field to be deleted, a warning message will be displayed. If the field is deleted, the web details will also be deleted.

It should be noted that there are many reasons for a delete operation to be refused. For example, the field is used in a file definition, other fields refer to this field and so on. In all cases the message issued will describe the reasons for the delete request to be rejected.
