Dear All,
I want to print my Items Serial Nos one after another in horizontal way & each one will be separated from a Comma(,) separator (Pic below). I don't want to use Array in this design because we already have some issues with arrays.

Please share if you have any other opinion in this regards.
Thanks in advance.

SerialNumbers := STRSUBSTNO(...);
then use SerialNumbers in Data Source.
