Standard Procedure
The purchase order (possibly with reference to a contract) is created and sent automatically when the kanban status is set to EMPTY. You define when the printout is made and the print layout is defined in message control. The vendor must be defined in the control cycle. The delivery address of the vendor can be defined in the control cycle. If the system finds no address here, it uses the plant address.
The vendor delivers the goods to the location defined. Two options exist for this; the vendor delivers the goods to a central goods receipt location or goods are delivered directly to the supply area. If the goods are delivered directly to the production line, the status change (by bar code or kanban board) triggers an immediate goods receipt posting using the target data. The goods receipt can also be carried out manually using the transaction for goods receipt (for example, if you want to make any changes or if you want to enter any additional data). When the goods receipt is posted the system changes the status in the background. For this type of goods receipt posting, the system issues an information message indicating that the goods receipt will be carried out for KANBAN.
Separate Goods Receipt
If the goods are delivered to a central warehouse so that the time between receipt of the goods, the goods receipt posting, and the actual availability of the goods is too high, you can separate the GR posting from the status change. Similarly, the system will not automatically post the GR when the status is set to FULL.
If the function "separate goods receipt" is active for the control cycle, then the system will not automatically set the kanban status to FULL when GR is posted (for example, when the goods are received in the central warehouse). The status is only set to FULL at the demand source.
It is also possible to set the kanban status to FULL first and then to post the GR separately later. (For example, you do not have to make a GR posting for each individual delivery on arrival. Instead, you can collectively post several goods receipts when the last delivery has been made).
