A chat bot recently developed by my colleagues Amir Nazim and Zain Khan at Mazik Global got me excited for how much room there is for enhancing the AX user experience and simplifying day to day tasks of an ERP end user. This chat bot right now enables you to find an existing purchase order in AX within a few seconds and also has the option of letting you create a purchase order in AX by answering a few questions of the bot. So if you are an end user that’s on the go or is finding it too cumbersome to open AX just to see details of a purchase order you can simply hit up this bot and get it to do the work for you. See the video below in which I talk to this bot to perform these tasks for me without having to say please. This showcases the true power of Odata entities and the bot framework.

In my previous post I showed how to capture a Trace of Payment Term creation that results in an etl file being generated. To read that trace we need to have Microsoft Dynamics AX Trace Parser installed. You do not need to be on the same machine that you took the trace on, you only need the ETL file. In the below video I quickly go over how to read a Trace file and the different options Trace parser provides. To see how to capture a trace read: How to capture a Trace log of any process in Dynamics AX 2012
Often times debugging a process is not enough to identify a bug or a query that is taking too long or the scenario only happens on a specific machine be it production or test and we need to get to the bottom of what is wrong that causes the issue. This calls for tracing the process and stepping through each cycle as it happened, thanks to Trace parser and the tracing cockpit provided in Dynamics AX 2012 we can capture every query executed and method called during that process. In the below video I show how to capture a trace log of any process.
Recently I was trying to find the best way to read only updated/changed data from AX for some entities like customers and vendors in D365. To do this in AX 2012 we would generally get a read only database copy made of production, enable modifiedDateTime fields and query the recently changed data from that database for our reporting needs but in D365 a cool new feature has been provided called change tracking. Through this you can get AX to push changes to your records to an external database outside of AX. A brief overview of this is that we use data entities to list what we need pushed out and configure them to export to our database. Read more on this here: https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/data-entities/entity-change-track
In Data management:
Register read only DB outside AX, providing its connection string:
Failed try of uploading data package to blob storage, error message: System.Reflection.TargetInvocationException has been thrwon
connection could be made because the target machine actively refused it
The change tracking information related to scheduler job 1090 and channel database group Default are only partially available, due to the headquarters data base change tracking retention period settling.
This creates the parm method which will not only get rid of the BP error but now you have your new field synced with the table creation field when an AIF service, a data migration entity or initialization is done.
This can be done by going through the web.config xml file which is located at “X:\AOSService\webroot”. Several parameters are configured here for for the application and i’ll go through some below, as a developer or administrator of Dynamics AX it is essential to know what configs are set here, so do give it a read and go through each element.
When creating a data entity for a data effective table there are a few properties we need to consider for our imports and exports to work correctly. There can be two scenarios.
1. Data entity is not date effective but one or more data sources within the entity are date effective.
For example we have to export details of a Party record. Now the Party record is saved under DirPartyTable that is not date effective but its First, Middle and Last names are stored in DirPersonName table that is date effective. In order to make sure that we get the latest names of this party while exporting data we need to configure the entity to do so, else it will send whatever record is first in DirPersonName against the party record. To configure it we simply need to set the Apply Date Filter Property to Yes for DirPersonName and make sure we add the ValidTo and ValidFrom fields of DirPersonName datasource to the entity field list.
Parent data source DirPartyTable, not DateEffective:
Child data source DirPersonName, that is date effective:
2. Data entity is date effective
What this means is that our data entity has at least one date effective data source and itself implements the date effective framework. Keeps track of latest and old records rather than overriding existing records on update. Will discuss this further in my next blog.

Mystery: IIS was stopped but D365 app was still running. How could this be? Its a single box Azure VM and everything, not just the AOSService but ISS itself is off. I verified the app is connecting to the right database and verified the webconfig file points to my own server so some other machine could not be hosting the App, I checked all configurations and none point to a different server so what magic is going on here.
I’m sure this would not be a mystery for everyone but for a short time it became a mystery to me and might become to some others as well so I had to get to the bottom of the magic happening. After some research I got to know that after the recent platform update 12 D365 is hosted on IIS Express, and as you know IIS express runs on visual studio, so if you have Visual studio open your app will be hosted. I ran a few scenarios after this so here is a list of them.
If Visual Studio is open, your IIS is stopped, D365 would still run on based on IIS Express.
If Visual Studio is closed, your IIS is stopped, D365 url will give you a Service Unavailable error
If Visual Studio is closed, IIS is running, D365 will run based of your AOSService site.
If Visual Studio is Open, IIS is running, D365 will run.
Thanks to a post by Faisal here which lead me to this. It explains what else was done wrt to update 12 like elimination of Admin user on lcs and availability of a Developer user.
