Hi Pravin

the Fwd consumption parameter mainly plays role with FCST consumption. i.e. your unconsumed FCST which is appearing in the SNP planning book will be changed accordingly. Depending on value i.e. in your case FWD consumption is 15 days , then sales order will consume the FCST for the FCST which is available with in next 15 days and create your unconsumed FCST key figure.

According to available unconsumed FCST, your total demand will get calculated

i.e. unconsumed FCST+sales order = Total demand.

Did I am able to understand your question properly and my answer help?

Thanks

Hi Amol,

You are right.

I have did testing in Q system according but results are not correct.like

I have taken below scenario.

April     May     June  

150     150          200

sales order for may 200

and I have fwd consumption: 30 days and 45 days

Whats should be ans for 30days & 45 days?

Hi Pravin

depends when exactly you have sales order in May.

but roughly for 30 days scenario, May fcst of 150 will get consumed. If you sales order is on 1st May then you are unable to reach for June FCST so June FCST should remain same. In case sales order is mid of May the 50 Qty FCST from June will also get consumed.

In case of 45 days scenario, May FCST will get consumed completed + 50 Qty FCST from June.

You can always check the FCST consumption details in /SAPAPO/RRP3 - Product View in Forecast tab.

Fwd Consumption: 90 days

Sales order: 2000 in april 15.04.2013

Total Demand April 3200 and may 750?

Hi

Looks like your FCST in APR is not getting consumed all.

is it possible for you to check on which day FCST is sitting in APR month.

Could you please check if APR fcst is sitting before 15 APR. As I said did you already checked the FCST consumption details in /SAPAPO/RRP3 - Product View in Forecast tab.

Please also check planning Strategy configuration details from you side

Hi Pravin,

First of all you need to check what is your planning strategy. Not all the planning strategies consume the forecast when you enter a sales order.

Now in the case your planning strategy does it (for example if you are using strategy 40), then note that after changing the consumption mode and consumption periors, you will need to create a new sales order to see how the forecast is consumed. If the sales order was created before the modification of the consumption mode and periods took place, then your changes will not be takebn into account during the consumption.
