Problem in Document Flow

Hi All,

We have upgraded to EHP6 and we are on ECC6.

I am facing a problem with the Document flow.

If i create the Sale Order - Delivery - Billing , i can see the Flow properly,

the problem starts when the Billing is cancelled and the Deliver is also reversed and deleted, the Flow disappears.

I can't see any flow from Sale Order.

Any ideas how to proceed.

with rgds
