Using * in Expression

[qlikviewwizard]

What is the ENAME = {'*'} in the below expression?

sum(

{<ENAME = {'*'},[PROMOTION_DATE] = {">=$(=yearstart(Date(HIREDATE),0,4)) <=$(=Date(HIREDATE))"},

[JOB] = ,COUNTRY = P({$<COUNTRY_CODE = {'US','UK'}>}),

>} [SALARY]

)

Thanks in advance.

that gives you all the values for that field, in some cases is can include nulls

I think it should have the same effect like {<ENAME=, ...>}  this would ensure that there is no limitation due to a selection in the field ENAME

Thank you All.
