The CDT result may indicate that actions must be taken, such as purchasing material or placing manufacturing orders for S- and M-parts. The actions are then shown to the right of the dotted line in the list, as purchase and manufacturing order suggestions for each material. Under Actions under the Check Delivery Times tab, you will find buttons to create actual orders based on the order suggestions.
The CDT is based on the assumption that order registration is made the following day, i.e. lead time + 1 day. The reason is that you can wait one night with the NET (Run Netting) and the NET then executes the actions. Or the CDT may be run at the end of the day and you cannot order until the following day.
The order suggestions created by CDT are not lot sized in the same way as during NET. The CDT calculates the quantity according to the stock refill (the planning formula EOQ is default) for all parts except for those with the lot sizing rule L (lot-for-lot).
The delivery period is according to the earliest requirement. There is only one order suggestion per part and calculation. The delivery period might be according to a shortage period that occurs later than the simulated requirement.
The Create P-order Button
By using this button, you can create purchase orders from the purchase order suggestions. Generating purchase orders are made via the Purchase Order Suggestion procedure. In that procedure you can edit reference, address etc. in the Search Form. The order printout takes place as usual after the Purchase Order Suggestion.
To the right of the button, you will see how many purchase orders that will be created and how many that are selected under the G. column in the list. In parenthesis, you will see how many of the purchased parts that have no supplier linked and for which you cannot create purchase orders.
If there is a difference between the Del. period and the New period on a row, a control question appears. You can then make a new calculation to adjust the difference. The same calculation takes place as during the Re-do with new period.
The control question during difference.
If there is a difference between the Del. period and the New period, it may result in a purchase for the wrong reasons if you do not recalculate. First of all, you may purchase too early if you have got a rescheduling suggestion with a negative diff for the position. Second of all, you may get other order suggestions when rescheduling since the Order Window will change in relation to existing orders.
The Create M-order Button
By using this button, you can create manufacturing orders from the manufacturing order suggestions. The Register Manufacturing Order procedure is then opened and the order rows are already filled in.
To the right of the button, you will see how many manufacturing orders that will be created and how many that are selected under the G. column in the list.
If there is any difference on a row, a control question appears and you have the possibility to recalculate.
Rejects
Shows the quantity that has to be manufactured or purchased to cover the shortage. Italic font means that the quantity differs from the reserved quantity. The lot sizing rule for parts that do not have the lot sizing rule L (Lot-for-lot) is the planning formula (default EOQ).
Period
Shows the finish period for manufacturing orders and the arrival period for purchase orders. Italic font means that the period differs from the requirement period. This may happen if the shortage occurred after the simulation.
G.
Here you select if the order suggestion shall generate an order. All order suggestions are selected by default.
Supplier Code
Shows the supplier code on the purchase order suggestion. The current supplier link for the part will be default. If the supplier is missing for a purchased part, "-Missing-" will be shown. To the right of the button Create P-order, you will see (in parenthesis) how many of the purchased parts that have no supplier linked and for which you cannot create purchase orders.
