GATP>transport and shipment scheduling(using CPS and condition technique)

Hi Gurus,

We are un-aware of how system really behaves everytime a CALENDAR is set-up to be on a specific day only.


Our client has some doubts but we, consultants, could not confirm if it is a standard behavior. Could you please help?

Sample:

Purchase Order is confirmed and has a requested delivery date of 09/11/2015. System is able to compute the below activity dates with the given duration of activity.

Activity Dates:

Duration:

We were just wondering if this is a right behavior of system to stretch-out the duration of LOAD activity if we have set the LOAD CALENDAR to only Friday.

Here is what happened:

Using backward scheduling (Stock is available), system calculates:

> 19/11/2015 as delivery date since stock is available (Start of UNLD and end of TRAN activity)

[gap is = TRAN duration = 48 hours]

> 17/11/2015 (End of LOAD and Start of TRAN)

[gap is = LOAD duration = 1 second] Here is what we are concerned: you would notice that the gap is not 1 second. system actually extends to 4 days in order to meet the loading calendar that should always be on FRIDAY - 13/11/2015.

> 13/11/2015 also known as LOADING date (End of PICK and Start of LOAD)

[gap is = PICK duration = 96 hours]

> 9/11/2015 also known as MAD (Start of PICK activity)

Now the question/issue are:

1. In real life, business does not really know where the item is. So setting-up a fixed calendar (in this case LOADING) should allow system to move the entire scheduling to which nothing is extended/violated. Should I report this to SAP as bug?

2. OR is this the normal behavior when setting-up a fixed calendar (where in system violates a defined duration in order to meet the calendar)?

If so, does it mean that there is a hierarchy where in LOADING CALENDAR is followed first prior to the LOADING DURATION? If there is such, could anyone show me what are the hierarchies?

Please help.

Thanks and regards!

Hi Zeek,

How do you know that I like CPS scheduling??

The system works fine in your case according to SAP standard. Due to your very restrict settings in the timestreams/calendars the system has no other chance to "stretch" the durations more or less to meet all the "restrictions". There is no prio or hierarchy to do so..the system has just to consider all restrictions (timestreams and durations) so that a valid scheduling result will be calculated at the end. The durations can not be less than maintained in the conditions, but the "gross" duration might be higher...

How should the scheduling result looks like instead??? I can not imagine any other "better" solution...

best regards,

Michael
