IPC : Access to other items in Valueform

Hello,

We have a pricing condition which require to read sub-items of a certain type in order to add subtotals.

I don't know how I can access to other items data in the method "overwriteConditionValue".

I tried the method "getSubPricingItemsUserExitRecursive()" of Interface "IPricingItemUserExit" but I don't really know how it works...

Could someone help me ?

Thanks,

Benoî
