when we use this?

[soniasweety]

Hi all,

what is the use of this field? " _Field"

and how this will work here?

    if(isnull("TempID"),"ID #"&'RO',"TempID"&'NEW') as _key_Filed, 

what is the result of it?

Did you try with an empty QlikView application and using a sample script (INLINE or AUTOGENERATE).

It helps a lot to clarify these type of questions

[soniasweety]

what is the linking between this and inline?  if you don't mind could please explain with some example

[Miguel_Angel_Baeyens]

You have an expression there, you can create your own sample QlikView app and test yourself the result, this will provide you more insights than telling the result.

Or do you have an issue with the expression or it's not working as expected?
