- Select the Simulate ROP/SST calculation menu item.
- On the ROP/SST calculation simulation panel, enter an item/warehouse combination to be used in the simulation. Complete the following field as well:
- Period start date
- Indicate if you want to use the period start date for this simulation. This date is used for retrieving forecast from a certain date, to give an estimation of demand during a certain time.
- If YES, then the first day of the present forecast period will be used as start date. This is the way ROP/SST is calculated in the Inventory calculations program.
- If NO, then today’s date will be used as start date. This is the way ROP/SST is calculated in the Create purchase suggestion program.
- You access ROP/SST calculation simulation. On this panel you select the method, and establish the parameters that you want to use to calculate the simulated ROP/SST for the item/warehouse combination displayed in the header.
- Service based
- Demand based
- You access ROP/SST calculation simulation again.
Click OK.
Select method
See About reorder point and safety stock (IBS Inventory Control) for a description of the calculation methods.
Enter parameters
The panel displays existing ROP/SST information that is retrieved from Work with service control codes. If you want to use other values in this simulation, you can change the information manually, or click Select service codes to retrieve another record from Work with service control codes.
You can also enter some additional parameters that are necessary for the ROP/SST calculation. Note: See the Panel help for detailed information for all fields. Click OK.
Calculated values
The result of the simulation is displayed in this section. These values reflect the method and parameters you have selected for the calculation. See Inventory control formulas for information about how the EOQ values are calculated. Exit the routine.
