Push baby push

Push systems are represented by MRP. Pull systems are represented by KANBAN. 'Going forward by moving backward is how one author described a pull system.'   Also as per author 'Gerald Najarian' 'They are the heart of a synchronized factory.  They permit synchronization by working backward through signals or triggers which cause production events to happen.  The experience of backward motion starts at the finished goods warehouse or shipping area and signals the previous operation - final assembly - when more finished goods are needed.'

In iVP CMS ERP , RAN (Release Authorization) and KANBAN works almost the same way. If you are receiving demands associated with KANBAN then make sure that trading partner master table is configured so that trading partner is enabled to 'Use Pull System.' This will signal iVP CMS that trading partner is using KANBAN and it is not under RAN control. This will allow iVP to accurately control which KANBANs are shipped and which are still outstanding.

Production orders created by voiding a production, by default will not be purged by MRP  in CMS . To authorize MRP to purge repetitive requirements generated by voiding a production PDMN23/1, F6=Options, 'Allow to clear repetitive planned schedules that  were created from voided repetitive production' must be enabled.
