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.

Understanding and How to use APIs Business Central - 2

Introduction:
In my last blog post (Business Central API -1 ) on Creating API in Business Central, we discussed all the commonly used properties of the page, query, and controls like field and data-item. In today's blog, we will be diving deeply into the validation of the data passed through the API endpoint, how it enters into the source tables and is manipulated to be inserted/modified into single or multiple tables.
Also, I will be demonstrating how APIs are to be used.

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.

Enum Object in Business Central - How to create and how to extend!

Introduction:
Since the dawn of Business Central Era (2nd April 2018 - Today), there are many new data types introduced by Microsoft.
One such data type is Enum(Enumeration). Essentially, what enumeration is having a single select value with multiple options at a given time!
Well, I know what your thinking what about the 'Option' data type.
Anyways, enough of talking let's just dive in!

1. Enum as an Object:
Just like Tables and Pages, Enum behaves like an Object.
Note that Extensible means that the Enum Object can be extended in another module. By default, this property is set to TRUE.



Enums and Enum Extensions behave differently. They follow a different number se…
