Master planning backward schedules the Supply forecast

Hi,

We have loaded a Supply forecast for a Manufactured item for the next 7 days.
The supply forecast represents the expected Factory production for the next 7 days based on the expected RM supply for each day (Note: we manually convert the RM qty to FG qty and enter that as the supply forecast as D365 MP planning is not a push model).

What planner wants to see is the capacity utilisation for each of the next 7 days based on the Supply forecast loaded.

However Master planning schedules the order backwards resulting in Capacity being always booked on the day prior to the actual production.

Has anyone come across this before? Why would Master planning schedule the Supply forecast backwards?

Note: I have played around with 'Backward scheduling capacity time fence', but the minimum i can set it to is 1 day, so doesnt really help in this scenario.

Any suggestions would be greatly appreciated.

Thanks

Pasan

RE: Master planning backward schedules the Supply forecast

MRP does always schedule backwards from the requirement date , therefore it will not be possible for you to achieve this in one go.

However, once the MRP generates the plan for you , you can overwrite the schedule by rescheduling forward the planned orders

I never used the Supply Forecast for a manufactured item ,but, if the outcome of that calculation is a list of planned batch orders ( if using process) or work orders if using discrete manufacturing, you can manually select all the orders and reschedule en masse

I would suggest using forward from order date so it will reschedule from the start date

when rescheduling you can also apply the finite capacity rules or finite materials.

i have highlighted them but not suggested what you should be using as you only know what the scheduling rules should be.

Thanks Jonathan for your suggestion.

We can't create actual production orders in the system as the company is a make to order business hence every Sales lines needs to be linked to Production order.

Just to give a bit of background, we are implementing this for a fishing company. They get the expected catch quantities (in RM weight) from each Vessel that is due to come in next week. Planner then wants to see if the factory has capacity to process the expected quantities each day and use that info to make decisions such as to add an additional shift or shut a line down if the quantity is too low.

Pasan,

If you know what you're going to produce, why wouldn't you just create production orders for the goods for the next 7 days instead of using supply forecast and MRP. By using a production order you can use the forward scheduling method to get the results you want.

MRP will always schedule backwards from delivery date and the date you enter in the supply forecast is the delivery date of the production order, not the date of the supply of goods.
