Question

is it possible to create a loop in the calculation script???
i am using epm 11.1.1.3

Not sure why you want to create a loop^^^ What John's getting at (I think) is that FIX statements and hierarchy almost always take the place of looping.
Where in another language I would go from 0 to n of an array to do stuff to that array, in Essbase I just (I am thinking BSO here) FIX on a level of a dimension and off I go without having to figure out how big an array is or how to loop it.
Having said that, I recently had cause to use the LOOP command. This was a calculation where I needed to calculate current inventory from last month's carryover. The outline looked like this:
Inventory Carryover
|_Stuff1 +
|_Stuff2 +
|_Stuff Available +
_|_More Stuff1 +
_|_More Stuff2 +
_|_Inventory +
All of the above members were stored.
To get this to work, I had to LOOP all twelve months. No, a FIX wouldn't do it. No defining the members as dynamic wouldn't work either. Believe me, I tried everything other than standing on my head.
It was the first time I have ever used LOOP and I've been using BSO Calc Scripts just about as long as they've existed. I apparently don't get out much or alternatively the LOOP command is rarely needed. You take your pick.
/*     Iterative loop to calculate Inventory and the total Inventory Carryover     */
FIX("Jan":"Dec")
     LOOP(12)
          "Inventory" = @PRIOR("Inventory Carryover") ;
          @IDESCENDANTS("Inventory Carryover") ;
     ENDLOOP
ENDFIX     /*     FIX("Jan":"Dec")     */It worked quite nicely and was fast. And what really made my day was that I got to use a new function in Essbase.
