Dear Friends,

After considering transpoartation lead time,pick/pack time,loading time & transit time system do confirm whether stock is available or not.....my doubt is whr do we maintain the above said times in the system?........

Hi saravanakumar

Transit time and Transportation lead time is taken from or maintained in Route

Loading time and pick/pack time comes from shipping point

You need to have clarity on backward scheduling and forward scheduling

For example you are creating a sales order today 15.02.2009 and the requested delivery date is 25.02.2009 from the customer side

Transit time is 2 Days

Transportaion planning time is 2 days

Loading time is 1 day

Pick/pack time is 1 day

Consider these settings

Now backward calculation System does a backward calculation first

25.02.2009 (requested delivery date) -- 2 days (transit days) -- 1 day (loading time) -- 2 days (transportation planning time) = that is on 20.02.2009 there should be enough stocks in the unrestricted stocks and system checks stocks for this day or date ,that is 20.02.2009 ,whether the stock is available enough

This date 20.02.2009 becomes the material available date

Note Transportaion planning time and Pick/pack time will run parallely and the higest of these two is considered for delivery scheduling so in our case Transportaion planning time is 2 days that is the highest and hence it is taken for calculation and not pick /pack time

If the system finds enough stocks on 20.02.2009 (that means it performs a availability check for 20.02.2009 depending on OVZ9 settings) that is material available date then it confirms schedule lines for that order this is backward

Same example order is registered today 15.02.2009 and if the customer wants stocks on 17.02.2009

This means 17.02.2009-2 days (transit days)-1 day(loading time)-2 days (transportation planning time) = 12.02.2009

The order registered date is 15.02.2009and the material availablity date is past 12.02.2009 or material available date goes to past.

This is illogical

This means backward is failing here and now forward calculation takes place

Forward calculation

If you have enough stocks today 15.02.2009 + 2 days transportation planning time+ 1 day loading time+2 days transit time = 20.02.2009

This means that is on 20.02.2009 the stocks can be confirmed for this order as against a requested delivery date of 17.02.2009

In forward the system will give 2 schedule lines first that is requested delivery date that is 17.02.2009(in our case) with ZERO qty and the second date as 20.02.2009 with full qty

In backward you will find only one date in the schedule lines which is the same as requeted delivery date that is 25.02.2009 in our case

Hope i made things little bit clear to you

Transit and transporatation planning will come from route if route is maintained otherewise it is taken as 0 days

Loading and pick pack time will be maintained in shipping pt if not maintained also then it is taken as 0 days (in enterprise structure logistice execution and your shipping point details it is maintained)
