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.

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…

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.
