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?

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