Abintio Record Format- Setting NULL to variable

I have a compoents input record format with a field set to NULL, like,

record

string(3) INPUT = NULL;

end;

Comp A -----FlowAtoB---------> Comp B

The above record format is the FlowAtoB. I can understand that this sets the value of INPUT to null. But, In case if i have value for this from previous component A, how this will behave?

I'm not able to understand clearly the use of this from the help document.

Solution

  • It is the default setting for your INPUT.
    There is nothing wrong with it.
    When component A will send the information to B it will behave just fine, as far as I'm concerned.

    Look at this example from my grpah that I'm working right now:

    string(30) salesperson = NULL("");

    When I send data it works ok.

    Try adding the brackets and quotation marks, but I think it was by default there.
    Hope this helps
