Hi Olga,
My requirement was to iterate one column and fetch 4, 5 values in comma separated format,
So I have used the String parameter to store those values, Since BODS does not support array,
My requirement was value1,value2, value3 etc and need to pass in another procedure this given string
like Str1 = "value1,value2,value3, value3",
however You can go through the below link which I have gone through for array implementation
