How to export data using TextBuilder in Business central.

Today we will see how we can data from business central table using new data type Text Builder.

To check how this data type work build small program as below which pick up data from customer table and export the data in text file.

pageextension 50101 CustomerMasterExtension extends "Customer List"
{
    actions
    {
        addlast(General)
        {
            action(DataExport)
            {
                Caption='Data Export to Text';
                ApplicationArea=All;
                PromotedCategory=Process;
                Promoted=true;
                Image=ExportDatabase;
                trigger OnAction()
                var
                CustomerMaster :Record Customer;
                Tempblob:Codeunit "Temp Blob";
                TextFileBuilder :TextBuilder;
                FileName:Text;
                InStreamData:InStream;
                OutStreamData:OutStream;
                begin 
                    FileName:='CustomerData.Txt';
                    TextFileBuilder.AppendLine('Customer No'+','+'Customer Name'+','+'Balance');
                    If CustomerMaster.FindSet() then repeat
                        CustomerMaster.SetAutoCalcFields(CustomerMaster.Balance);
                        TextFileBuilder.AppendLine(CustomerMaster."No."+','+CustomerMaster.Name+','+Format(CustomerMaster.Balance));
                    until CustomerMaster.Next()=0;
                    Tempblob.CreateOutStream(OutStreamData);
                    OutStreamData.WriteText(TextFileBuilder.ToText());
                    Tempblob.CreateInStream(InStreamData);
                    DownloadFromStream(InStreamData,'','','',FileName);
                end;
            }
        }
    }
}

If you look at the above code it is taking required data from customer table and export the data in text file as below.

To get more insight of data type have a look at MS documentation from below link

How to change primary key in Business Central Table

Recently one of my customer asked me to add few more fields on primary key and I was looking at the customer like he asked something which is daunting task to be done with business central as everybody aware of that we can not change the primary key fields when table is already having data as while deploying the app it throws an error as below

Even I tried using Force sync also but it is still failing to deploy the app as this is breaking change for the app.

Now question is how to do this and overcome from such situation as your customer is behind you to do that.

To make it work we need to use ObsoleteState and ObsoleteReason that means we need to make your table obsolete and create a new table with new primary key and change the references in all those object where the object is referred.

To make the table obsolete mention the property as below.

Obsolete property value

ValueDescription
NoNot obsolete. This is the normal/default setting.
PendingWill become obsolete in a future version.
RemovedHas been made obsolete.

After making above table obsolete created new table with the new primary key.

Next point is how to transfer data in the new table .

To transfer data from obsolete table to new table used Installed code unit . Additionally you can use temporary table to update data from old table to new table.

If you would like to learn more about ObsoleteState Property then visit here.

Hope this will help you.

Business Central allows to change App Name Publisher of app.

With the release of Business Central Wave 2 2021 aka BCV19 lot of new features has been added to make life easier of developer and/or customers.

Can we change App name and/ or publisher name to meet marketing branding ? If you ask me till V18 it was not possible to change that and in V19 it is possible.

Lets see how it works.

Here is my app.json file

Publish the app

Changed the app.json

Hopefully this will help to give branding name to your app even after published.

How to allow your app to debug in business central

With the release of Business Central Wave 2 2021 aka BCV19 new version of AL language is also published.

Do you remember this post where in I explain the use of showmycode property from app.json file. With this property we have only one option either we allowed to debug and download your app or vice versa.

Now with new version of AL language this property has been deprecated and new property has been introduced resourceExposurePolicy where in we get leverage to control your app from debug ,download the app file.

This property will be automatically added when new project is created as below.

If you can see in this property we have three options which can be used to control the app and your IP.

  1. AllowDebugging :- Allow to control the debugging of your app when it is published. The default setting is true.
  2. AllowDownloadingSource :- Allow to control the download of your app source code .The default setting is false.
  3. IncludeSourceInSymbolFile: Allow to control symbol to be included in the source code of package. The default setting is false.

Can I add resourceExposurePolicy and showmycode property together ?

With the introduction of this new property in app.json file we can not use showmycode property as it will show an error and warning as below.

Hopefully this will help us to control our IP and provide more security on our app.

How to modify table data in business central

This week one of the customer post few transaction and found that one of the field user enter some wrong information. In ideal situation user need to reverse the transaction and post correct transaction which is safest approach.

But do you remember those old days where we have access to the table and can modify the data but with business central this ability no more available . I just build one small extension to modify the data in the table where in we can modify the posted data .

Important: It is not recommended to change data in the tables directly as it will cause inconsistency in database and make database vulnerable.

Just check following video to check small amount of work I did.

Additionally I found blog from Volodymyr Dvernytskyi for Data Editor .Please have a look into it.

Let me know your feedback.

How to create Custom Notification in Business Central

This blog post I am writing based on request of one of the follower.

Even though notification is not new business central world but today we will see how we will write custom notification and get notified for certain validations.

To create notifications I added following simple scenario that when my page get opened it should show some notification.

Lets see how we can do this.

To generate this notification I have used customer list page and subscribe on OnOpenPageEvent to execute my notification.

In this notification whenever page will get open it will show notification and whenever user click on Contact Us it will redirect to my blog.

Once this piece of code is published and as soon as customer list page opens you will see the result of notification as below

Hope this will help you.
