| # Display Production Planning Production order plans in Shop Floor Control are originating from: The Enterprise Planning module (see Origin of production orders for more details). Warehousing (planned INA orders). Manual entries in the Production Orders (tisfc0501m000) session. Order of Operation The basic inputs for planning of shop floor production are: The routing data The order data The item data The BOM data The operations are related to each other using network planning. That means that the operations do not have to follow each other in terms of their sequence numbers (10 -> 20 -> 30). For each operation, you can define in the Next Operation field which operation is next. This enables you to build a flexible set of relationships between the operations, including parallel operations. Note If you want to check or modify the sequence of several operations at once, use the Operation Relationships by Order (tisfc1102m000) session. In the Routing module, you can only define sequential routings. If you use phantoms in the bill of material (BOM) of the end item, this can result in a branched network. When LN generates a production plan, it links the last operation of the routing that you defined for the phantom item to the operation specified on the BOM-line of the phantom-item, which is an operation of the main routing or of a parent phantom-routing. Timing of operation In the Production Planning (tisfc0110m000) details session, you can see a number of dates that relate to the operation, and also various rates and times. You can modify the dates when the operation is carried out by changing the date and time of the Remainder Start Date field. The horizontal line represents the passage of time.

I | Queue Start(Next Operation) or Planned Delivery Date ( Start Date) (if no next operation, the Planned Delivery Date is used)
J | SU+Run (Next Oper.) or Requested Delivery Date ( Start Date) (if no next operation, the Requested Delivery Date is used)
(*) | The transport related fields are related to the transport to and from a subcontractor in case of operation subcontracting.
The production time is the sum of the setup time (3) and the run time (4). The dates on the horizontal line are calculated by LN according to the amount of time you specified for each of the following lead-time elements of a routing operation: Queue time Setup time Cycle time Wait time Move time Note Click the Move All button to adjust the production dates of all the operations before and after the current operation to take account of the changes you have made. If you use this method to adjust the production dates of the operations, LN does ignores the setting of the moving methods in the Previous Operation(s) field and the Subsequent Operations field in the Production Orders (tisfc0101s000) session: even if you set these fields to Do Not Move, LN still replans all the operations. To change the number of resources on an operation If you want to change the number of resources on an operation, you can do this by changing the value of the Man Occupation for Production field, or the Machine Occupation field. However, changing the number of resources does not affect the cycle time, and, consequently, the production time. On the other hand, the total production costs will change due to the extra resources. To prevent that production costs change when you change the man occupation or the machine occupation, the cycle time must be recalculated. You can choose to do so, because when changing the man or machine occupation, a question pops up to ask you whether you want the cycle time to be recalculated: If you click Yes, the cycle time is recalculated. So, the man occupation or machine occupation is changed, including the total production time, but the costs stay the same. For more information on how the cycle time is recalculated, refer Recalculation of cycle time when changing man occupation or machine occupation. If you click No, the changed man occupation or machine occupation does not affect the cycle time and the production time. However, the total production costs will change to reflect the change in man occupation or machine occupation.
