Business Central XmlPort: Why the XML Declaration Looks Missing

I have read this doubt somewhere: “My XmlPort is exporting XML correctly, but the header <?xml version="1.0" encoding="UTF-8"?> seems to be missing.”
At first glance, it looks like Business Central is not generating the declaration — but in reality, it’s more about how the file is viewed.

Properties of XMLPORT:

If you open the file in Edge or any other browser, you will not see the line <?xml version="1.0" encoding="UTF-8"?>.

If you open the file in Notepad, you will be able to see the <?xml version="1.0" encoding="UTF-8"?>.



🔍 Why It Looks Missing

  • When you open the XML in a browser (like Edge or Chrome), the browser parses the XML and hides the declaration, showing only the structured nodes.

  • When you open the same XML in a text editor (like Notepad), the header becomes visible because the editor shows the raw file content.

  • So the XML declaration is there, but browsers simply don’t display it.

🎯 Conclusion

Your XML is not wrong — the content is complete and valid. The declaration line may simply be hidden by the tool you use to open the file. If your integration or external system requires it, you can easily add it with a few lines of AL code in the XmlPort.

 Hi Colleagues, Today, we will discuss how we can search custom table data using the " Search Company Data " feature in Business Central. For more information regarding the " Search Company Data " feature, you can refer to the official Microsoft documentation: Search Company Data I have added a test customer to the default customer table.  and created three test entries in the Test Header custom table.

Dynamic 365 Business central: How to Automatically Insert Line Breaks After a Specific Character Limit

Image
Suppose, you may have a requirement to break long text into multiple lines after a certain number of characters in Business Central. For example, when dealing with lengthy descriptions in fields like "Work Description," it's important to ensure the text wraps properly to maintain readability. In this scenario, I have implemented a solution using a tableextension to automatically insert line breaks after a specified character length (45 characters in this case). The code takes the input string, breaks it into lines, and formats it accordingly before writing it back to the "Work Description" field. This ensures that the text is displayed in a neat and user-friendly manner in the system. Code:   tableextension 50140 MyExtension extends "Sales Header" {     trigger OnInsert()     var         TypeHelper: Codeunit "Type Helper";         Crlf: Text[2];         InputString: Text[2048];       ...
