Error messages

Error messages are supported everywhere. 

Simply perform the “ERROR()” command in NAV and the message will be shown on the scanner.

Warning/Confirmation/Message

When a warning is wanted, the string ”ForceWarning” can be prefixed to an Error message.

The process flow is:

1. This will produce a warning, that the user can choose to Cancel or Confirm
   
   
   1. Cancel will return the user to the previous screen
   2. Confirm will automatically repeat the reuest with a “Force” tag included
      
      
2. The Force tag tells the backend that the Process can now be completed and NOT halted by the ERROR command.
   
   

Example

Below is the XML Request from the mobile device to the backend.

• Note how a <Force> tag is included.
  • Use this to determine whether to issue the ERROR.
  • If the Force tag is included, do NOT run the ERROR, because this is the second "round trip", telling you that the user selected Confirm
  • See code example below

IF NOT Force THEN BEGIN
  ERROR('ForceWarning:' + STRSUBSTNO(MobWmsLanguage.GetMessage('QUANTITY_ERR'),Quantity,ActualQty));
END;

Line break

Line breaks / Carriage Return, can be performed by using the "\" character in NAV/BC.
