Special Ledger - Plan version 0

Hi all!

I have setup Special Ledger with plan version 0 active. If I manually create planning on plan version 0 on projects or cost centers, the plan $ are replicated in SPL as whished. But If I plan hours in a network activity, the plan values are not reported in SPL.

When I try to transfer historical plan data to SPL, I get the following error message :

E Activity KPPE is not supported

I tried to find this activity in SPL configuration of the ledger, but it is not available. Is there a way to allow automatic cost calculation of projects plan version 0 in SPL?

Thanks.
