How can I build a For Loop in alteryx?

[sriramramakrishnan03]

I have a requirement where I need to execute the following "For' Loop

for(x=i,i>0,i=a)

the initial value of a=length and the second iteration, the value becomes a-b post some truncation of b rows and so on.

The function that I am going to perform inside the 'For' Loop is some filtering of data.

Can you pls help me?

@sriramramakrishnan03 
Alteryx is manualiping data on a gloal level, meaning all in and all out.

So I dont think there is an identical For function but I am sure there is something we can do with Multirow Formula too.

Can you provide a sample input and out?

@sriramramakrishnan03 I agree with @Qiu , you can also try the Generate Rows Tool, which is work like a loop
