To add a text constant to a codeunit, use the following procedure.
To add a text constant
- Select the C/AL Editor, choose View, and then choose C/AL Globals.  Note Note- For more information about how to open the C/AL Editor, see How to: Modify an Existing Codeunit. 
- In the C/AL Globals window, choose the Text Constants tab. 
- In the first available Name field, enter the name of the new text constant.  Note Note- There is no naming convention for the text constants. We recommend that you use the unique ID for the name, as described in steps 4 and 5. 
- Select the line in which you entered the name of the new text constant, and on the View menu, choose Properties. A unique ID number has been automatically assigned to the text constant in the ID field. 
- Copy the ID number from the Properties window to the Name field in the C/AL Globals window. For example, if the ID number is 1001, specify Text1001, in the Name field. 
- In the ConstValue field, choose the AssistEdit button. 
- In the Multilanguage Editor window, enter ENU for the language and then enter the text. For more information, see How to: Enter Text in the Multilanguage Editor  Note Note- If you set the application language to English (United States) before opening Object Designer, you can enter the message string directly into the ConstValue field in the C/AL Globals window. Open the Multilanguage Editor to be sure that the text is saved as English (United States). 
- In the C/AL Editor, copy the name of the text constant to the place where you want the text value to appear. 
Example
In this example, Text1001 is a number that is available in the text constants number series for that object.
|  Copy Code | |
|---|---|
| IF FileName = ' ' THEN ERROR(Text1001); | |
In the C/AL Editor, when you move the cursor into the new text constant, you see its contents in the status bar.
