MRP100 Dates

Al,

Bonnie hit several of the key points in her reply - especially regarding your 1st question / message.

In your origianl email, there were 2 messages / questions - the 2nd was regarding MRP100 dates.

There is another system parameter regarding MRP100 and dates as follows with the std help text pasted below which is:
Prorate Forecasts?: (1,A) - Yes or No

Y = if the planning start date overlaps the forecast time period, then the system will prorate the total quantity of the forecast based on the number of days from the plan date to the end of the forecast.
(N = don't do this)

What this means - If your forecast covers a month (for example) and your planning date is mid-month, what do you want to use as the forecast? The full forecast qty or 1/2 the forecast qty.
Ex. forecast start date = 9/1, forecast end date = 9/30, forecast qty = 100, planning date = 9/15
Prorate = Y means the forecast qty used will be 50
Prorate = N means the forecast qty used will be 100

Remember also that the start date of the forecast is the need date for MRP purposes. This means a forecast that covers a month, say 10/1 (start date) thru 10/31 (end date), the system assumes the the full qty is due on the start date (10/1).

Another note about forecast start and end dates is that they serve as the basis for orders consuming forecast (if you choose that method) and therefore should (typically) not have date gaps. This means that if I intend to enter monthly forecasts but enter start dates AND end dates of 10/1, 11/1, 12/1, etc, thinking I am entering monthly forecasts, the only customer orders that will actually consume the forecast are those on the first day of the month. You need to enter an end date that is the last day of the month in order to accomplish forecast consumption as customer orders are received during the month.

Remember also that the prorate forecast option will interact with the method code.

Suggest testing on all of this - as I'm sure you will do - but I think most of this logic is similar throughout most of the BPCS versions.
