Open the 
Reason Codes window.
Specifies reason codes. Reason codes are used to indicate why an entry was created. When you set up reason codes, you can place them on entries and assign permanent codes to specific journal templates and journal batches. When the codes are linked to a journal line or a sales or purchase header, the program will mark all entries with the reason code when it posts them.
The window contains a line for each reason code.
