Hello everybody,

today I want to write a short note on three states of fields existing in Acumatica:

1. Exists but is empty
2. Exist and have value
3. Has null

If to speak about string, it can exist like this:

1.  
2. Some value
3.  

Do you see difference between 1 and 3? Not easy. As usually developers of C#, show this difference like this:

1. ""
2. "Some Value"
3. null

And following screenshot with explanation shows how it works in case of SOAP contracts:

 so, while you make integration, keep that in mind
