Report Data Source specifying field names

rahul_jnk

This might be a very basic one but I'm not getting the difference when you specify field names with Record prefixes and without prefixes under a data item.
For example I select Data Item as Customer and in the next line I select Column and add Customer."No" instead of just "No" in Data Source Column. Why specifying this way have different effects?

Sorry my answer was not clear ...

You can write such Code like above or use "Sales Line" as DataItem and use the fields like
"No." or "Sales Line"."No.".

If you are in your "Sales Line" DataItem it's "like" a WITH

The should not have a different effect.

The difference is just that you are in the context of the upper DataItem. So there are know field names.
You can also write Code like ..

WITH Customer DO BEGIN
  INIT;
  "No." := 'some value';
  Customer.Name := 'some other value';
  Customer.INSERT;
END;

Hi mik ,
Sorry if I wasn't clear, I was talking about Report Dataset Designer not C/AL .
If we mix the two formats, I guess its taking as different variables or something.

No, no difference at all. If you omit the dataitem name, the compiler will use 'implied with' to find the context - which will be the same context ('Customer' in your example) as when you do not omit the dataitem name.
