How SQL Profiler can save your day by Identifying Lengthy Processes in Microsoft Dynamics NAV / Business Central

Problem Statement:

While building customization for Microsoft Dynamics NAV / Business Central ERP, at times the customization is so heavy that we as developers do not realize how much load we put on the SQL Database which the backbone of the system.

One example of this situation is, I had built a system that can create a Cash Receipt during accepting Payment in terms of Cash from the Customer by temporary passing an entry through the Cash Receipt Journal. There was also a Payment Application code that applied(reconciled) the Payments and the Invoices of the Customer that ran posting of any financial entry concerning that specific Customer.

During this attempt of creating Cash Receipt, the posting would block the Customer, Customer Ledger Entries and G/L Entries Tables which was as per design. And it wouldn't allow anyone to make an entry during this period and it would take approximately 20-30 seconds.

To get out of the Deadlock, I was forced to restart the NAV Server Instance through Power Shell.

Introduction:

In this blog, I will mention how SQL Profiler helped me realize that the Cash Receipt Posting was taking way more resources than expected. There was no metric to even judge what was going on and which query tool precisely how much amount of time to execute.
This also helped me change the process to follow to post Customer Cash Receipts.

Pre-requisites:

  • Microsoft Dynamics NAV / Business Central On-Premise
  • Microsoft SQL Server Management Studio
  • Microsoft SQL Server
  • Understanding of SQL Profiler

Books & References:

https://docs.microsoft.com/en-us/sql/tools/sql-server-profiler/sql-server-profiler?view=sql-server-ver15

Demonstration:

1. Open NAV on one side of the screen:
Goto Sessions in NAV search, select the session you want to use SQL Profiler and Start Full SQL Tracing.
NAV Sessions - Enable Full SQL Tracing

2. Open SQL Profiler on the other side of the screen:
Goto SQL Server Management Studio > Tools > SQL Profiler
SQL Server Profiler
SQL Server Profiler - Login 

Trace Properties - General
Check “ShowPlan XML” under Performance Counter.
Trace Properties - Event Selection - Showplan XML

Check “SP:StmtCompleted” Completed under Store Procedures.
Trace Properties - Event Selection - SP:StmtCompleted 

Check all the options under “Locks”
Trace Properties - Event Selection - Locks

3. Run the processes in NAV so the effective background SQL Query Execution can be tracked in  SQL Server Profiler:


Trace SQL - SQL Profiler
4. Tracking which function or line of code is taking the maximum time.:
In this case, check the transaction with a maximum duration
Trace SQL - SQL Profiler - Showplan XML - Exec














After finding the Query taking a long time to run, you can check the corresponding CallStack in C/AL or AL.
Trace SQL - SQL Profiler - NAV Code - Exec

Thus, using this method, you should be able to trace your NAV execution issues.

Conclusion:

Thus, to conclude, I had no idea about how SQL Profiler worked. With the help of a friend
from Microsoft Support (Mr. Aananth Rajadevan). I learned what all components are present in  SQL Profiler and how to monitor what is going on and find the correct C/AL Code and rectify it.

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
