Error messages

You want to prompt the user to Confirm a message.

Error Message

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

ERROR('This is an error message');

Confirmation Dialog

To display a confirm dialog,  you prefix the error message with”ForceWarning:” 

The process flow is:

1. The user can Cancel or Confirm
   
   
   1. Cancel will return the user to the previous screen
   2. Confirm will automatically repeat the result, but this time 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.
   
   

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;

Display dialog when opening an Order

Show a Confirmation Dialog when opening a e.g. Receive, Pick -order.

Modify function GetLockOrderNoAndPrefix_FromBackendID in Codeunit WMS Order Locking

Add a XML Node variable "XMLForceNode" and the following code.

IF MobDocQueue."Document Type" = 'LockOrder' THEN 
  IF UPPERCASE(MobXMLMgt.FindNodeAndValue(XMLRequestDataNode,'Force',XMLForceNode)) <> 'TRUE' THEN 
    ERROR('ForceWarning:My message here');

Line-Breaks

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

Note

• “Unplanned Count” in Codeunit WMS Adhoc Registr.
• When opening a Receive/Pick/Put-away/Move Order, the warning is performed in Codeunit WMS Order Locking
