MRP - Calc of Distribution in Order qty

Hi Experts,

Need your help to understand distribution in order qty.

For bulk materials we are creating order for 10,000 kg qty & in the recipe operation we have defined base qty as 1000 kg that means we are producing 1000 kg material daily. In the production version distribution key we have define ZXYI which says eual distribution.

Considering above master data we are expecting order to run for 10 days and produce 1000 kg each days. So in MD04 it should saw 1000 kg against each day...If it start on July 20 then it should end on July 29 & 1000 kg each day. But wondering it saws 9500 kg in MD04 for each days.

I'm struggeling to find from where & how it calculates 9500kg. Please note we have 100% capacity running 24 x 7. There is tolerance %.

Input appreciated.

have you checked the MRP1 & MRP2 views of your material master?

for example, what is set up in Lot size data...

Lot size is EX lot for lot order qty

Min lot size - 1200

Max size - 15000

Hi Eric

Is difficult to understand exactly what is happening without checking the scenario on your system.

Which kind of order are you creating? Production orders or planned orders? Is this order created manually or by MRP?

Can you please provide some screenshots of MD04?

Here I created one scenario with real example, Earlier given number were just test. Base qty in BOM 59K. PO qty 600K which runs for multiple days. It saws process hr 244.1 considering 59K --> 24 hr. So it should saw 59K for each day in MD04 but it saws 54,545.454 that is wierd. I attached few screen. Let me know if you need more input.

Eric, Ord qty = 600,000

Prod start date = 19th July'13 and Prod end date = 29th July'13.

Totally 11 days between the two.

So 600000/11 = 54545.45.

That sounds simple at the outset. Are we missing some thing else?

My question is when my production capacity per day is 59K then why system is considering  54545.45 per day?

My expectation is system to confirm 59K production per day...Hope this clarify my question..

I think srini already answer your question...

Since you use equal distribution strategy,it will be splited equally among working days.Thus it won't consider capacity per day..

As far as I know,it won't take capacity into account during the distribution.

I had a similar concern before..Hope it helps u.

Hi Monst yang for usefull information. I created Z99 eual distribution rule as per attached link and assigned to strategy, but still it does not resolved my issue. Still it is keep creating order with less qty than base qty of recipe...

I'm not sure what I'm missing here.

Hi Monst, What changes I required to do, so it consider capacity?

Hi,Eric:

My example is just to distribute the demands according to operating time.

PO:140 pcs

For example:day 1: 2 hours   days2: 8 hours  days 3:4 hours

then it will distribute as: 20 pcs   80 pcs  40 pcs in MD04

In order to make it,run MRP using lead time,setup correct distribution strategy ..I don't have environment on hand ,I cann't list all detail steps..
