Bulk Inserts - Dynamics NAV

Microsoft has introduced the bulk insert functionality which will allow the developers to write high performance code. 

What is Bulk Insert : 

Microsoft Dynamics NAV automatically keep all the records in a buffer and then send them to Microsoft SQL server at a one time. Before this modification, insert happen in the order of the C/AL code running and had lot of server calls which will slowdown the application and also lock the tables many number of times before completing a one transaction.

Advantages of Bulk Insert : 

 1. Number of server calls are been reduced and it directly improve the performance of the application. 
 2. Improve the scalability. This was achieved by delaying the actual insert until the last possible moment in the transaction and by doing this Mictrosoft was able to reduce the amount of time that tables are locked. 

However this functionality has few constrains and it is a must to understand them before using this functionality. 

Client will send the records to SQL server when the following occurs, 

  • When the COMMIT was called to commit the transaction
  • Call MODIFY or DELETE on the table
  • Call and FIND or CALC method on the table
Buffer Insert functionality will not used if the following conditions are met,
  • If the application is using the return value from an INSERT call,
    • IF (GLEntry.INSERT) THEN
  • If the table that you are going to insert the records into contains any of the following
    • BLOB fields
    • Fields with the AutoIncrement property set to YES
Addition to above mention constrains Dynamics NAV Debug will not stop in the exact INSERT statement but, due to delayed Bulk Insert, in a position right after the INSERT AL Statement sequence.  To read more about this issue use the following link : MSDN

 Following code example cannot use the buffer insert since it contains a FIND call on the GL/Entry table within the loop.

 IF (JnlLine.FIND('-')) THEN BEGIN  
    GLEntry.NEXT := GLEntry."Entry No." + 1  
    GLEntry.NEXT := 1;  
   // The FIND call will flush the buffered records.  
   GLEntry."Entry No." := GLEntry.NEXT ;  
  UNTIL (JnlLine.FIND('>') = 0)  

Therefore Developer need to redesign the code to maximize the usage of Bulk Insert.
Following is a modified code of above example and this code segment use the bulk insert functionality.
 IF (JnlLine.FIND('-')) THEN BEGIN  
   GLEntry.Next := GLEntry."Entry No." + 1  
   GLEntry.Next := 1;  
   GLEntry."Entry No.":= GLEntry.Next;  
   GLEntry.Next := GLEntry."Entry No." + 1;  
  UNTIL (JnlLine.FIND('>') = 0)  
 // The inserts are performed here.

Advantages of using Microsoft Dynamics NAV development environment in creating a Database

In this blog post I will not be discussing about the process of creating a NAV DB. In here I will be discussing about the advantages of using Microsoft Dynamics NAV Development Environment in creating a DB. 

Microsoft has provided main 2 ways of creating a Dynamics NAV database in SQL server. 
 1. Create the DB using SQL Server Management Studio
 2. Create the DB using Microsoft Dynamics NAV Development Window. 

What is the best way ?? It is very hard to pick a one from above two methods because both are almost same and required similar steps.

However I feel creating the DB from Microsoft Dynamics NAV environment is more safe and provide few advantages. 
As you know if you just create a DB using SQL Management studio, and didn't do any modifications to the DB creation process then the DB will create a default filegroup call PRIMARY. This filegroup will be the primary filegroup and all the tables will be created on this filegroup.

It is not recommended to use the default filegroup for our usage. Leave it for SQL and create a separate filegroup and then work on that. 

So here comes the advantage of using Microsoft Dynamics NAV development environment to create a DB. Because when you create the DB using Microsoft Dynamics NAV development environment, system will automatically create a new filegroup called "Data Filegroup 1" apart from the Default filegroup and make that new filegroup as default. Every table will be created in this new filegroup and we do not have to do anything on this. 

There are few other additional advantages as well. i will write about them in my next few posts. 

Thank you and Regards,

Reset NAV 2013 or 2013 R2 security and settings

If it is required to delete users, user properties, debugger breakpoints or session event related info; then use following TSQL code. It simply delete the data from the tables directly and allow you to use the NAV as a fresh settings. 
 USE [YourNAVDatabase];  
 delete FROM [dbo].[Access Control];  
 delete FROM [dbo].[User];  
 delete FROM [dbo].[User Property];  
 delete from dbo.[User Personalization];  
 delete from dbo.[User Metadata];

HTML Tags and Microsoft Dynamics NAV 2013 Reports

It is annoying to change the report layouts according to customer requirements, because every time developer needs to open the design view and then go to layout in the Visual Studio. 

What about giving the option to the customer to change the report presentation and the layout of the report. Does NAV directly allow that? No. 

but so far I have found two different workarounds for this, 
1. Design the report in the report designer as usual way (need very few additional modifications) then create couple of functions and tables which allow the user to change the color, size, font, spacing of the text without opening the report design view (Using HTML Tags). 
2. Create the report layout in text editor (Notepad, Wordpad, Word) and save it as a HTML file and then passing the values to the HTML file using a DLL.

Today I will describe the first method and will give more info about the second one later (will share the DLL and code with it, most probably a video guide).

Here we go..

 1. First create a table with following fields and data types.

2. Provide a object ID and name and save it. 

3. Following is the report we are going to modify.

4. Run the report and see the output of the report before do the modification.

5. Create a code unit and in that create a function called "Format Field"

6. In the function, define a record variable for the table which we created in the step 01 and 02.

7. Go to parameter tab and define 3 input variables with the data types define below.
  • ReportID_In - Integer
  • FieldName_In - Integer
  • Value_In - Text 100

8. Set the return variable name to "Return Value" and set the data type to Text 100

9. Go to Format Field in the code unit and write the following code
 Format Field(ReportID_In : Integer;FieldName_In : Text[30];Value_In : Text[100]) ReturnValue : Text[100]  
 recReportFormatting.SETFILTER(recReportFormatting."Report ID",'%1',ReportID_In);  
 recReportFormatting.SETFILTER(recReportFormatting."Field Name",FORMAT(FieldName_In));  
 IF recReportFormatting.FINDFIRST THEN BEGIN  
   ReturnValue := '<html><font size =';  
   ReturnValue := ReturnValue + recReportFormatting."Font Size" + ' color =' + recReportFormatting."Font Color" + '>';  
   ReturnValue := ReturnValue + ' ' + Value_In;  
   ReturnValue := ReturnValue + '</font></html>';  
   ReturnValue := Value_In;  

10. Compile and save the code unit and you are done with most of the coding necessary.
Now lets move to the next part of the development. Which is the easy part.

11. Go to the report and go to the design view of it.

12. Then click on the "Cust. Ledger Entry" data item and go to the code of the trigger.
 We are going to modify the customer name according to the parameters set in the earlier defined table.
In this report we need to do few more modifications. We are going to write the coding in the highlighted area and before that we need to define few more variables.  

13. Define following variables as globe variables in the report.
  • cduReportFormat - Codeunit - Report Formatting (50000)
  • textname - Text 100
  • ReportID - Integer
  • CustomerName - Text 50
  • CusNameForReport - Text 100

14. Write the following code in the report where I have highlighted before. 
This will pass the report ID and Value to the function we defined early and will return a HTML tag text.

2:  CustomerName := CustAddr[1];  
3:  CusNameForReport := cduReportFormat."Format Field"(ReportID,'Customer Name',CustomerName);  

15. Go to design view of the report (dataitem) and add the following variable to the report data set. 

16. Then open the report in Report Layout mode and as you can see there are various text boxes with different values. We are going to change the format of the customer name column. Therefore we do not need the existing column. Just delete the first text box in the upper left corner.  

17. Now we need a new data holder to add the customer name, and that place holder should be able to read and format our HTML string. Can we do that easily or do we have to modify lot of things? No we don't!
Just add a text box and double click on it and then right click. 

Then click on the "Create Placeholder"

18. In the Placeholder property window click on the HTML- Interprete HTML tags as styles radio button. 
This will tell the placeholder to read the HTML tags and convert them to the styles. 

19. Then go to the Value and select the Customer name data field from the data set. 

20. Close the designer and compile and save the report.

21. Now go to the table which we have created at the early stage of this demo. 
22. Run the table and insert the values as following. 

23. Now go back to the reporting and run the report. 

As you can see customer name styling is changed accordingly. 

We can use this functionality very creative way. This is just a demo to show that we can use the HTML tags as styles. If you have the creativity you can do marvelous  thing to satisfy and exceed customer satisfaction. 


Happy testing guys!!

Thank you and Regards,
Tharanga Chandrasekara.

Styling Dynamics NAV 2013 Page Values

ERP is all about providing critical information to the users with very user friendly manner. Therefore It is always essential to draw attention to the important values, fields in a page. It allows the user to use the ERP very user friendly manner and allow to provide very critical information in very simple manner.

If the customer want conditional coloring of rows based on some conditions, as developers didn't had the functionality support from the earlier versions of Dynamics NAV Role-Tailored Client.

With the new versions of Dynamics NAV, this was allowed and was able to change the color of the text depending on the predefined conditions. 
Even though the functionality was allowed, still have limitations for the formatting. Such as, the number of colors support to this functionality is fixed.

Following is a sample for the styled text page in the Dynamics NAV 2013 R2

Sample of Styled Page in Dynamics NAV

Formatting is done by using a property value for style on a field and setting it to a pre-defined value.
Go to the design view of a page and select a field that you want to change the color and then go to the properties of the field.
(Design Page -> Property of the Field want to change the color)
As you see 'StyleExpr" was already set to "FALSE" and system will show the value in default manner.

To modify the style follow the following steps,
1. Design the page
2. Define a global variable of type text ( StyleText Text 20 )
3. Assign the Style Code value to defined variable in the "OnAfterGerRecord" trigger depending on the condition.
Following is a sample code.

4. Then go to the property of the field and scroll down to the bottom of the property page and assign the variable to the "StyleExpr"

5. Compile and Run the page. (Following is the final output - web client)

Thank You and Best Regards
