Load order in Concat() function

[sunny_talwar]

Hi Guys -

While helping someone on the community (First Function() in a table graph), I stumbled across a scenario where I wanted to use Concat() function and wanted to sort is by load order. I know this can be done easily by adding a RecNo() or RowNo() in the script. But the idea is if I don't want to make changes in the script, is it still possible?

I thought of using Aggr() function, as Stefan (swuehl‌‌) once mentioned in a post that Aggr() function usually sorts by load order. But that doesn't seem to be true in this particular case. Have a look at the attached sample:

Sample Data:

Table:

LOAD * Inline [

Dim1, Val1, Val2

a, ak3, 1

a, ak1, 4

a, ak5, 2

b, ak4, 5

b, ak2, 2

];

I tried these expressions:

=Concat(DISTINCT Val1, ', ')

=Concat(DISTINCT Val2, ', ')

=Aggr(Concat(DISTINCT Val1, ', '), Dim1)

=Aggr(Concat(DISTINCT Val2, ', '), Dim1)

The order for Expression1 and 3 I am getting is this -> ak1, ak3, ak5 and I am looking for -> ak3, ak1, ak5 when Dim1 = a

Best,

Sunny

I think I found the solution to my problem:

=Concat(DISTINCT Val1, ', ', Aggr(RowNo(), Dim1, Val1))
