Posted on by Rahul Mathur

I have a question related to "no. of characters" which can be return when we call a custom DLL from Business Central 17.
Is there a limit on characters which can be return by a DLL?
My DLL returns JSON which is about 5K characters. When I call that DLL from BC17 AL, it only bring 1024 characters and truncate the rest.
I remember when we were calling Web Service there was a limit of 1024 characters but thought it's gone as now TEXT variable is practically unlimited.

Any idea about this one?

Hello, Thank you for your reply.

For a text variable, it's 2048 to the power 3.

In table field it's increased from 250 characters to 2048.

I'm calling a .Net DLL now will try to read JSON as memory instream.

Above shows the limit is double that, not unlimited. Maybe bigtext is a better idea.
