Hello Renatas,
I changed customizing of processing category = 00104 'Fixing - Contract - Settlement' for my transaction type and created new forward transaction with initial activity = Fixing.
Executed fixing, but it doesn't help. Flow 1031 still has zero value (as same first example).
And I have some suspicious about 'posting block status' = 3 'activity does not allow posting'.
I guess it's incorrect.
I checked customizing for 1031 flow - it is relevant for posting !
Do not understand
