Variables frustration

[alessio.missio]

Hi all,

I'm getting mad on PDI variables.

I just need to set a variable in a job, then after a Trasformation increment it by 100 and then run that Trasformation again for n times.

So if the flow will run 4 times I expect to have my variable set it to 300 (0, 100, 200, 300).

I'm using the Set Variable step with this syntax :

VAR = ${VAR}+100

What I get at the end is 0 + 100 + 100 + 100...

How can I achieve this ?

Any help will be greatly appreciated.

That's because Variables are strings.

You would need to process the variable in the Javascript step.
