Disable The Annoying Dialog After Posting in Business Central

by Steve Endow

Why does this dialog appear by default after EVERY document posting in Business Central?

This is an annoying dialog

I was recently on a call with my colleague Tanya Henderson to review some accounts payable payment processes in Business Central.

After I posted a purchasing invoice, she told me to click No on this useless dialog, saying that she has to train all of her customers to click no, and she wished she could get rid of it.  

Can this dialog be turned off?  If not, can a PTE suppress it after posting?

Challenge accepted!

Exploring Business Central Custom Table Indexes

by Steve Endow

In my last post, I poked around in SQL to see what custom fields looked like in the database for a Business Central table extension.

While looking into fields, I happened to notice the table index that is automatically created for the table extension.

Automatic Table Extension Index

If we look at this index, we see it is a Clustered Unique index for the "No_" field only.

Default Clustered Index on Table Extension

Why is this default index created automatically?  This Table Keys docs page briefly mentions the default Clustered Index on table extensions.

Is Agile Development viable for Business Central customizations?

 by Steve Endow

To the Agile Advocates (tm) who will immediately protest "Of course it is!" before reading on, I ask:  

Hear me out.

Reference:  What is Agile?

Reference:  What is Agile Development?

Reference:  Manifesto for Agile Software Development

Book:  Agile Project Management for Dummies 3rd Edition

Book:  Agile Estimating and Planning

Book:  Scrum: The Art of Doing Twice the Work in Half the Time

Disclaimer:  I'm not an Agile expert.  I'm someone who has tried to learn about Agile (on several occasions) and tried to understand if and how some Agile practices might be used in the projects I work on.  I'm asking lots of questions, for which I'm having a difficult time finding answers on my own through part time self-study.

"Agile Development". It sounds cool. It sounds compelling. If you've ever suffered on a long, complex project that was over budget and seemed like it would never end, you'll likely appreciate some of the benefits that Agile claims to offer.  You'll read the Principles behind the Agile Manifesto and say, "Yes, please!"

It definitely appeals to me.

But then there is the reality that I personally work in.  Over the last 26 years, I have done consulting and development work mostly for "mid-market" customers in the US.  Based on my years of experience, admittedly with organizations and teams that didn't have "best practices", I'm having a difficult time trying to map Agile practices to the mid-market ERP projects that I typically encounter.

My inquiry is not about whether Agile is good or bad.  I'm trying to understand if Agile is a good fit, or even a viable option, for my customers and my projects.

Business Central Chat with Stefan Maroń: Designing Complex Pages in BC

 by Steve Endow

Stefan Maroń was kind enough to have an impromptu live stream with me today to help me understand how to design complex pages in Business Central.  We discussed how I might develop replicate the functionality of the .NET interface of my "Data Generator" application in a Business Central page.

In addition to designing the UI of a data generator, Stefan shares some very valuable information about how to process background tasks in Business Central, which I was unfamiliar with.

Here is a link to the "Coding4Performance" series on his blog:

Docker Engine Enterprise and Mirantis Container Runtime for Business Central Developers

by Steve Endow

NOTE:  This post relates to Docker Engine Enterprise and Mirantis Container Runtime on Windows Server.  I don't believe this relates to or affects Docker Desktop.  But let me know if I missed anything regarding Docker Desktop, and let me know if I have any details wrong regarding Mirantis Container Runtime and its use with BcContainerHelper and Business Central Docker containers.

On September 27, 2021, Tobias Fenster shared a Microsoft announcement about the future of Docker Engine Enterprise, sometimes referred to as "Docker EE".  

https://twitter.com/tobiasfenster/status/1442533006812631047?s=20

This Microsoft announcement comes almost 2 years after Docker was acquired by a company named Mirantis, in November 2019.

The Microsoft announcement indicates that technical support for the Mirantis Container Runtime will be transitioned to Mirantis.

Mirantis also published a post explaining the transition, and discussing options for receiving support for Mirantis Container Runtime (aka "MCR"), and free licenses for up to 9 "nodes" for Windows Server users.

So what does this mean for Business Central developers who use Windows Server?

When I first read the Mirantis blog post, I assumed I would need to contact Mirantis to take advantage of their "special offer" to receive a free license for MCR for my Business Central development on Windows Server.

This page on the Mirantis web site explains the "beta pricing" offer is available until December 31, 2021.

I thought that I would request licenses for a few nodes, which would cost me $0.  But, that would NOT include any support.  

I'm okay with the $0 price tag, and if I did need support for some reason, I would be open to paying a reasonable price for support.  I would even be open to paying $50 per node to receive limited support, but based on the information on the web page shown above, it is not included by default with the 1-9 or 10-50 note packages by default.  But it may be possible to purchase support separately for 50 nodes or less.

I'm assuming that after December 31, 2021, Mirantis will come up with new pricing, and MCR will not be free for Windows users.

What about "Moby"?

But today I re-read the Mirantis blog post and noticed this.

Wait, what?

I'm a Business Central "developer".  I am not using my containers in "production".

Does that mean that I can use the "default Moby engine"?  Whatever that means?

I posted my initial thoughts about this to the hive mind called Twitter:

https://twitter.com/steveendow/status/1445494238955720713

I tagged our resident Business Central Docker expert, Tobias Fenster to see if I was missing anything.

I'm glad I tagged him, because he shared some important information about how Docker works and additional considerations about the Mirantis announcement that I believe are pretty important to Business Central developers.

Tobias replied, and mentioned that the free Moby engine has "No client component".

I didn't know what this meant, so he generously explained further.

So while we could run BC containers using Moby, technically we would not have a docker.exe "client" to manage or create the containers on Windows Server.

It seems we will need MCR

You can read the rest of the Twitter thread if you would like, but after a few more questions from me, and answers from Tobias, these are the points I think are important for BC developers who use Docker Engine Enterprise on Windows Server.

1. If you do NOT get a license for the Mirantis Container Runtime (MCR), and choose to use the "Moby engine", that is ONLY the "server" (daemon) portion of the solution.  Moby will allow you to host containers, but technically, that does not include the docker.exe "client" or any tools or utilities to help you manage your containers.  You could try to find other Docker tools, but Tobias suspects that limited interest in Docker on Windows means limited options for Docker tools on Windows.

2. As a Business Central developer, I regularly use the docker.exe "client" command in PowerShell to manage containers and images.  So I believe I will still need that, and therefore will need MCR.

3. The BcContainerHelper PowerShell module that BC developers use to create Business Central containers relies on the docker.exe "client" tool to create and maintain and interact with containers, so I assume that the full MCR solution will be required in order to continue using BcContainerHelper.  (there may be other ways to download a docker.exe client or equivalent, but I have no yet researched that)

Given this, I will want to request the MCR licenses from Mirantis so that I can have access to the full MCR product suite on my Windows Servers and continue to reliably use BcContainerHelper.

If you are aware of other solutions that provide a Docker client and related tools on Windows Server and work well with BcContainerHelper, please let me know.

Creating a simple text file using AL in Business Central - Sample Code

 By Steve Endow

On January 23, 2021, I recorded a video showing how to create a simple text file using AL in Business Central.

Here is the video:

Below is the sample code from that video.

Learning Business Central Development from Scratch Video Series

By Steve Endow

If you are new to Dynamics 365 Business Central development, join me on a journey to learn how to develop Business Central Extensions using VS Code and the AL language.

I have been developing business software for many, many years, but I am completely new to Business Central, AL, and VS Code.  And I am also new to Docker and PowerShell.  

Basically, I'm having to learn everything from scratch.  

I'm writing blog posts and making videos to share the learning resources I'm using and share my learning journey.

Business Central Download Symbols Error: No such host is known

By Steve Endow

UPDATE:  After researching this type of Windows hosts file name resolution issue, it seems there are dozens of possible reasons why the problem can occur.  I suspect my case was one of the simpler versions, and fortunately flushdns worked for me.  Here is a forum thread with examples of several rather odd causes and solutions.

This morning I tried to create a new Business Central AL project in VS Code.  I used AL Go! to create the project, set the server name in the launch.json file, and then tried to Download Symbols.

Very simple, very easy, right?

Nope.

No soup for you!

What? I performed these exact same steps 2 days ago on this same machine, and I was able to download symbols without any issues.

Here is the full video of the troubleshooting process:

https://www.youtube.com/watch?v=zLb0tjwuThY

I closed VS Code, relaunched it, created a new project, and tried again.  Same error.

Looking at the error log in VS Code, I saw "Error: No such host is known".  Say what?

Learning Dynamics 365 Business Central Development From Scratch: Introduction

By Steve Endow

If you've never done any NAV or Business Central development, but would like to, join me on this journey to learn how to develop in Dynamics 365 Business Central.

I've never used Dynamics NAV and don't even know what C/AL looks like.  I don't know what a "code unit" is.  Until a few months ago, I had never used Docker.  And although I've used Visual Studio for years, I don't really know how to use VS Code.  I know that Business Central uses a language called "AL", but I can't write a single line of AL.

Based on my experience so far trying to learn the Business Central application and Business Central AL development, I expect this will be a long journey for me.  Because I am still working mostly with Dynamics GP customers and projects in my day job, I have to learn Business Central in my "free time", so it isn't something I'll be able to pick up in just a few months.  A year ago, I gave myself 2 years to be "minimally competent" with the Business Central application and development.  Well, work gets busy and life gets busy, so I think I'm currently well behind on that 2 year timeline, and need to catch up.

Even though I have over 15 years of experience working with Dynamics GP and .NET and SQL Server, Business Central is a completely different world to me.  My fundamental knowledge of ERP software and software development is somewhat helpful as background, but it seems all of the specifics are completely different.  I want to learn Business Central and AL development and have the same comfort level that I have with Dynamics GP and .NET.  That will take time, and will require some pretty intensive learning.

So I'm starting from scratch.  Learning from scratch.  This is the start of that journey.
