How Optimizing Microsoft Dynamics NAV / Business Central Can Save You From Trouble.

Problem Statement:


After my client's implementation in NAV, the system was working smooth and flawlessly. An important issue was that the client couldn't close their books due to the change in Business Processes and even the customization was evolving as per the changing Business Process. This lead to serious slowing down of the system, filtering and finding records was a pain.

When all the options ran out, we default to calling the Microsoft Support for help!
They suggested upgrading the NAV CU versions which was way painful as all the data needed to migrate and again the system would face a downtime which my client couldn't afford!!

Out of nowhere we were suggested reindexing the tables in NAV which were impacted the most as a periodic activity.

Pre-requisites:

  • Microsoft SQL Server Management Studio (SSMS)
  • Microsoft Dynamics NAV
  • Understanding of SQL
  • Understanding of NAV Server Instance 

Reference:

https://docs.microsoft.com/en-us/powershell/module/microsoft.dynamics.nav.management/restart-navserverinstance?view=businesscentral-ps-15
https://blog.sqlauthority.com/2007/01/31/sql-server-reindexing-database-tables-and-update-statistics-on-tables/

Solution:

1. Restart NAV Server instance using PowerShell and Task Scheduler:
Create a PowerShell with the below command.

Restart-NAVServerInstance -ServerInstance <NavServerInstanceName> -Flags


Then add the Powershell to Task scheduler to schedule the Restart of the NAV Server Instance.

Trigger for Task Scheduler
TaskScheduler calling PowerShell Script

2. Restart SQL Server to free-up RAM using PowerShell and Task Scheduler:

SQL Server by design consumes a lot of RAM and does not free it up. You can limit the RAM usage but this doesn't account for higher runtime performance during maximum load.

Create a PowerShell Script to restart SQL Server

Get-Module -Name VMware* -ListAvailable | Import-Module Restart-Service -Force 'MSSQLSERVER' 
Import-Module SQLPS -DisableNameChecking Set-Service SQLBrowser -StartupType Automatic Start-Service "SQLBrowser" 
$instanceName = "localhost" 
$managedComputer = New-Object Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer 
$sqlServerAgentInstance = $managedComputer.Services['<YOUR SQL SERVER NAME>'] 
$sqlServerAgentInstance.Start()

Again, you add this to TaskScheduler.

3. Re-Index the tables in the SQL DB:
Reindexing the table in SQL DB is a maintenance activity that speeds up the fetching activity for Microsoft Dynamics NAV / Business Central.

Reindexing SQL Script
Creating Script (Stored Procedure ) which runs reindexing for each of the tables in the Database.

Executing Reindexing Stored Procedures

Executing the Stored Procedure for ReIndexing. The Stored Procedure for Reindexing can also be triggered as a Job in SQL.

Conclusion:
Thus using these techniques you can optimize your existing NAV/ Business Central On-Premise. Although Restarting NAV Server Instance and SQL Server help in optimizing NAV for the day to day usage.
A long term and a periodic solution are using Re-Indexing which typically boosts performance from 50% - 60%. I have observed that a page which would take 10-15mins to load, takes around 5 mins to load.

Creating APIs in Business Central - 1

Introduction:
While writing a blog on Automated Testing in Business Central, I was going through sample apps provided by Microsoft and realized that the complexity is nowhere close to what examples Microsoft has provided on docs.microsoft.com. In this blog, I will try to explain how APIs work and how to be creative with the implementation. Also, an API which were in beta are finally out with version V1.0 in the April 2019 release let's see some important key things from development aspects.
This blog is going to be theoretical one kindly bear with me.

How Business Central Modern Client Reverse Compatibility With NAV Can Help You Improve Your Work.

Introduction: Today, I was playing around with Business Central Modern Client (Windows App).
Out of curiosity I was trying to login to one of my NAV 2017 through SSO.
Pre-requisites: Microsoft Dynamics NAV with SSO configured
Microsoft Dynamics Business Central
Demonstration: 1. Business Central App - Main Page:

Clicking on locally hosted service and putting in the credentials configured for NAV 2017 SSO, we get.
Still skeptical when Business Central login into NAV.

2. Business Central App - Reverse compatible with NAV 2017:


Well well well...
Look whose here.
NAV disguised as  Dynamics 365 for Financials.

I think we all agree that Business Central Modern Client is a WebApp version of Busines Central Online. Basically just like browser in an App.
The difference is that it can connect to NAV as it is just like a browser.

3. Does Business Central Modern Client follow DynamicsNAV protocol?:
Well, it simply does not.
It would be amazing  if it did, as it would mean that we could deal with runni…

Generic way of Attaching Documents on any Record of the Page in Microsoft Dynamics Business Central - Template Code

Problem Statement: In Microsoft Business Central, there is a way to attach attachments only on Documents or Master Table records. But, what if this requirement is for other tables such as Opportunities, custom tables, etc. Introduction: I have seen many developers afraid to touch the attachment-related customization as it seems complicated.
Well, I have found a solution and here it goes.
In this blog, I'm attempting to create a generic template for code that needs to have an attachment feature on any table that you like using AL Code.
This means that you simply cannot copy-paste the same code for all the tables but a simple change in variable sub-type will ease your work significantly
