Posting Date for Consignment Settlement(T-code:MRKO)

Hi All,

Whenever we settled any consignment invoices, the posting dates of the

invoices are always on the date of the settlements done.

Say now is 1.7.08 but I want the settlement date to be on 30.6.08.

Where in T-code:MRKO can I pre-defined the posting dates? It seems like

there's no such processing option now.

Please advise.

Thanks,

Teo
