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.

Business Central Custom Fields and Default Field Values

by Steve Endow

When you add new fields to an existing Business Central table, what happens?  

What does Business Central do in the database?  How does Business Central handle default field values?  

I didn't know the answers to these questions, so I decided to do a few tests.  For fun, obvs!

To keep things simple, I created a Table Extension object in AL.  I assume this applies to creating custom tables and adding fields to an existing custom table, but I figured a Table Extension would be simpler and easier to test with, and I learned a few more things about table extensions in the process.

Mitigating WiFi deauth attack with Protected Management Frames in Unifi (aka 802.11w Management Frame Protection MFP)

by Steve Endow

Note:  In case the title didn't make it obvious, this post has nothing to do with Business Central.  I wanted to document my learning because I found very little reliable or current information on mitigating WiFi deauth attacks, as of May 2022.  If I got anything wrong or if you find a good resource covering this topic, please post a comment and let me know.


When I'm not trying to learn Business Central, I like to learn about computer security.  I'm not a computer security expert by any means, just someone who finds it interesting as a side hobby.

While learning about password cracking several months ago, I learned about Kali Linux, an amazing distribution that includes lots of different computer and network security tools pre-installed.

In order to learn how to use Kali Linux and the security tools it includes, I decided to try to learn how to crack my WiFi password.  It seemed like a fun exercise, and it was.  But it just happened to teach me something entirely unexpected.

While following the instructions in this "Hacking Wi-Fi" guide (which had some minor omissions--I recommend using this version instead), I was quite surprised when I read this step:

"...disconnect the clients connected to the target network..."

Wait, what?

Power Automate Business Central Journal Line Import Error

by Steve Endow

NOTE:  I'm encountering this error as of April 22, 2022.  If this ends up being a bug in the Power Automate BC connector that is fixed, I'll post an update.


A customer is interested in importing General Journals into Dynamics 365 Business Central using Power Automate.

Simple, right?  Just one Power Automate flow, right?  How hard could it be, right?

Well, it depends.

This is the error that I get in my Power Automate environment.

You must specify a journal batch ID or a journal ID to get a journal line

When I ask why it doesn't work, I get responses that seem to indicate that it should work.

"It works fine for me"

"You must be doing it wrong"

"Did you try doing it this way?"

But no matter what I try, the flow gives me the same error:

ErrorCode: Application_DialogException  You must specify a journal batch ID or a journal ID to get a journal line.

Resolving Business Central AL Warning AL0603 - Implicit conversion to a value of type Enum

 by Steve Endow

While copying a standard Business Central Web API page to a new project to create a customized version of the API page, I encountered this compiler warning:


AL0603 - Implicit Conversion to a value of type Enum


An implicit conversion is being performed from a value of type 'Integer' to a value of type 'Enum "Attachment Entity Buffer Document Type"'. This conversion can lead to unexpected runtime issues. This warning will become an error in a future release.AL AL0603
(field) "Document Type": Enum "Attachment Entity Buffer Document Type"


I am vaguely familiar with this error, and I think I resolved it months ago in a different Business Central project, but I completely forgot how I figured it out and how I resolved it.  So I'm writing this post to remind me when I forget again in 6 months.

Getting Access to The Top Secret Business Central Insider Program

by Steve Endow

If you are a Dynamics 365 Business Central developer or ISV, you should definitely get access to the Business Central Insider program.

Business Central Insider Program

I don't know why the BC Insider program is so cumbersome to join, but I'm guessing it involves lots of lawyers. Which is unfortunate, since I think BC Insider is an essential program for any BC developer.

I thought I had a link to the BC Insider program on my BC Resources page, but apparently not, as it seems to require several steps, and is not available through a single URL, unfortunately.

I did a few DuckDuckGo searches, but came up with nothing.  I then did several Google searches, but still couldn't find any Microsoft pages explaining how to join the BC Insider program.

After several searches, I finally found Daniel Rimmelzwaan's excellent blog post from February 9, 2022:

Thankfully, he documented the process for signing up for Business Central Insider after going through the same puzzling search for one of his clients.
