Dual Write - How Pricing and Inventory On-Hand works in CE?

In the recent updates of Dual Write, Microsoft released a pricing and inventory on hand integration in CE. Real time pricing calculation and inventory on hand as per FinOps business logic. In this post, I wanted to cover how it seems to magically work.

As you know by now, Dual Write uses a push architecture. Where either FinOps pushes to CE or CE pushes to FinOps. Both call a web service on the other side to sync data. Any errors that occur are presented to the user in real time. However, the pricing and inventory on-hand feature is different. These two features pull limited calculated data as needed. Watch the "Prospect to cash in dual write" tech talk from Microsoft and you will see why. 

You wouldn't want to integrate (replicate) inventory levels or pricing logic in CE. The reason this is done this way is because integrating this kind of data would cause performance problems or a lot of chattiness. So, what Microsoft has done is a pull the data as needed (pull architecture). 

In the below screenshot, you can see there are two new buttons on the Quote or Order form. 

1. On-hand inventory - Shows real time inventory on hand information in a pop up form.

2. Price Quote/Order - Recalculates the price on the quote or order on the lines

The Inventory On-hand form shows calculated data from FinOps.

Now lets have a look at the back end that makes this work.

There is a bit of javascript that is used in CE to call OData Action methods. Below you can see the javascript resource file in the solution. You can see how the PriceOrder method calls a web service by passing in 4 parameters. The Entity name (hopefully this is fixed as it is using the label), the sales order number, the company and the action method to call.

Following this through in FinOps. You can see the DualWriteProjectConfigurationEntity has a RunDocumentAction method which takes the same 4 parameters. 

If you dig deeper, this then triggers a method on the entity that was specified. Dirtying up the record to force a sync back to CE. 

Maybe another time I can dig deeper and give some feedback.

AX - How to use Map and MapEnumerator

Similar to Set class, Map class allows you to associate one value (the key) with another value. Both the key and value can be any valid X++ type, including objects. The types of the key and the value are specified in the declaration of the map. The way in which maps are implemented means that access to the values is very fast. Below is a sample code that sets and retrieves values from a map. static void checkItemNameAliasDuplicate(Args _args) { inventTable inventTable; Map map; MapEnumerator mapEnumerator; NameAlias nameAlias; int counter = 0; ; map = new Map(Types::String, Types::Integer); //store into map while select inventTable { nameAlias = inventTable.NameAlias; if (!map.exists(nameAlias)) { map.insert(nameAlias, 1); } else { map.insert(nameAlias, map.lookup(nameAlias) + 1); } } //retrieve fro...

AX - How to use Set and SetEnumerator

The Set class is used for the storage and retrieval of data from a collection in which the values of the elements contained are unique and serve as the key values according to which the data is automatically ordered. You can create a set of primitive data types or complex data types such as a Class, Record or Container. Below is sample of a set of records. static void _Set(Args _args) {     CustTable       custTable;     Set             set = new Set(Types::Record);     SetEnumerator   setEnumerator;     ;     while select custTable     {         if (custTable && !set.in(custTable))         {             set.add(custTable);         }     }     if (!set.empty())     {    ...

Approve Workflow via email using template placeholders #Dyn365FO

Dynamics 365 for Finance and Operations has placeholders which can be inserted into the instructions. Normally you would want this to show up in the email that is sent. One of the most useful ones is the URL link to the exact record that you are approving. In the workflow configurations use the placeholder and build up your message. Towards the end it has workflow specific ones. The URL token is %Workflow.Link to web% . For the technical people the token is replaced in this class WorkflowDocumentField. This is what I inserted into my email template. <BODY> subject: %subject% <BR> message: %message% <BR> company: %company% <BR> for: %for% <BR> </BODY> Should look like this. The final result looks like this. If you debug these are the place holders that are put together.
