How to untruncate fields in business central
In Business Central, field values are generally not truncated at the data level. What you’re seeing is usually a page layout or UI issue.
The practical solution is to adjust the page, either through personalization or a page extension, so the control can display the full value.
For standard pages, users can resize the column or personalize the page (Settings → Personalize). Business Central stores column width per user, which resolves most truncation cases.
If the issue affects all users or a custom page, the correct fix is a page extension where the field control is updated, for example, by enabling multiline display for text fields.
Example (AL):
field("Description"; Rec.Description)
{
MultiLine = true;
}
This approach aligns with the Business Central tech stack and allows the full value to be displayed without changing the underlying data.
Normally the question is how to truncate 
It’s not a standard process of truncation until and unless somewhere is crossing the character limit.
