Description

It can be useful for the Warehouse worker to view an Image of the Item to handle.

These functions can display images

• Locate Item (Thumbnail)
  • Show Image (Full view)
    
    
• Order Lines (Thumbnail)
  • Show Image (Full view)
    
    
• Any custom List
  
  

Prerequisites

• Android app and associated configuration file, version 1.3.0 or newer 
  
  

Supported NAV versions

*Note that you may need to download the newest Tasklet objects from Tasklet University that include the new CodeUnits.

• NAV 2013 R2
• NAV 2015
• NAV 2016
• NAV 2017
• NAV 2018

Please note

• Images are cached by the app to reduced bandwidth requirements
  • But still, do keep in mind the image file size
    
    

How to set it up

1. Import images in Items
2. Import NAV objects
3. Enable in NAV code
4. Configure the Mobile App

Step 1 - Import images in Items

Import Picture on the relevant Items.

Step 2 - Import NAV objects

The following two objects will be create

• Codeunit 6181391 - MOB WMS Media
• Codeunit 50011- RunMe Setup MOB WMS Media
  
  

1. Re-Compile the object (Important)
2. Run the object "RunMe Setup MOB WMS Media"
   1. This will set up Image support, by creating a Mobile Document Type called "GetMedia" pointing to Codeunit 6181391
      
      

Step 3 - Set Max Message Size

On the servier tier administration, SOAP tab.

You must set this property to the highest possible size of image. 5120 = 5 megabyte.

Warning: Failing to increase this value, will result in images not being stored in NAV.

Step 4 - Enable in NAV code

Enable for Warehouse Pick, Put-away and Move

In Codeunit 6181388 - MOB WMS Toolbox and function CreateWhseActLinesResponse

1. Create a Global variable for the Codeunit Called "MOBWMSMedia" of type "Codeunit" and subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest(WhseActLineTake."Item No.",XMLOrderLine,NS_BASE_DATA_MODEL);
// MEDIA

Enable for Warehouse Receipt

In Codeunit 6181372 - MOB WMS Receive and function CreateOrderLinesResponse

1. Create a Global variable for Codeunit Called "MOBWMSMedia" of type "Codeunit" and Subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest(WhseReceiptLine."Item No.",XMLOrderLine,BaseDataModelNS);
// MEDIA

Enable for Purchase Order Receipt

In Codeunit 6181372 - MOB WMS Receive and function CreatePurchaseLinesResponse

1. Create a Global variable for the Codeunit Called "MOBWMSMedia" of type "Codeunit" and subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest(PurchaseLine."No.",XMLOrderLine,BaseDataModelNS);
// MEDIA

Enable for Transfer Order Receipt

In Codeunit 6181372 - MOB WMS Receive and function CreateTransferLine

1. Create a Global variable for the Codeunit Called "MOBWMSMedia" of type "Codeunit" and subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest(Transferline."Item No.",XMLOrderLine,BaseDataModelNS);
// MEDIA

Enable for Locate Item 

There are two modifications to be made.

Modification 1

In Codeunit 6181382 - MOB WMS Lookup and function LookupLocateItem

1. Create a Global variable for the Codeunit Called "MOBWMSMedia" of type "Codeunit" and subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest("Item No.",XMLLookupResponse,MobXMLMgt.GetNodeNSURI(XMLResponseData));
// MEDIA

Modification 2

In Codeunit 6181382 - MOB WMS Lookup and function AddLookupResponse

1. Create a Global variable for the Codeunit Called "MOBWMSMedia" of type "Codeunit" and subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest(ItemNo,XMLLookupResponse,Namespace);
// MEDIA

Enable for Planned Count

In Codeunit 6181376 - MOB WMS Count and function PhysCreateOrderLinesResponse

1. Create a Global variable for the Codeunit Called "MOBWMSMedia" of type "Codeunit" and subtype "MOB WMS Media"
2. Insert the following snippet

// MEDIA
MOBWMSMedia.AddItemImageToRequest(ItemJnlLine."Item No.",XMLOrderLine,BaseDataModelNS);
// MEDIA

Step 4 - Configure the Mobile App to show Images for desired workflows

You must enable images for the workflows you want to use them in, i.e. "Pick" and "LocateItem" etc..

Please note

The prerequisites in the beginning of this article which are:

• Mobile WMS for Android App version 1.3.0 or newer
• application.cfg on the scanners contains "listConfiguration" with images i.e.:
    <listConfiguration id="LookupWithImages">. 
• If both these are not meet, contact Tasklet Factory.
  
  

Perform the following modifications to application.cfg

In general, to start using images you need to substitute the listConfiguration for the workflow with a new listConfiguration called the same but with "WithImages" appended.

Change where the  "OrderLines" list is used to instead use "OrderLinesWithImages".

For Pick

For Put-away

For Receive

Show Image

To show the image in Full Screen, you can enable the "Show Image" action.

Remove the comment tag surrounding the showImage action.

A technical description of how Images are requested from the back-end

How Images are technically requested from the back-end.

Images on Order lines

1. A sourceID XML tag appears in the App Configuration file, application.cfg.
   1. This is named "ItemImage".
2. When the Mobile Request Document Type "GetXXXOrderLines" is reponded to, an Image tag is included.

1. 1. This is also named "ItemImage".
   2. The value of the tag is a combination of Item No. and the date and time when the Item / Image was modified.
      This way, whenever an Item is modified, the App will know by the value changing and request the Image again, now receiving an updated image.
      
      
2. When the sourceID matches with the answer to the request, additional requests are made for the images needed. 
   1. One request after the next. These will have the Document Type "GetMedia".

Troubleshooting that no image is being saved
