Problems Encountered At Import
Extensions may not be imported correctly for the following reasons:
Text format
The command file can be created with any word processor, such as Word, but it must be saved in Text Only format. If it is in Word format, it will not be recognized by the command interpreter.

Use Notepad, Write, or Wordpad and avoid formatted text.
Open transactions
Metamodel extensions will be visible in a transaction only if you dispatch or refresh your transaction.
Dash at the beginning of commands
A dash (-) indicates a comment. Lines beginning with a dash are ignored.
End-of-file character within the commands
Certain file concatenation operations can insert an end-of-file character within the command file. In this case, processing stops at this character.
