one can use the subsession tfacr2140s0001 to change the status of a sales invoice when the invoice is expected to become doubtful. The question: which one is the main session frome where the mentioned subsession can be started?

Hi,
U must create a transaction type that uses tfacr2140s000 as first session, then, from Maintain Transactions u have to create a batch, insert that transaction type, chose it for transactions and follow the screens that will pop-up.
Hope this is useful.
