hi all,
how does system calculate the basic start & finish dates for a planned order for an FG/ SFG?
shall it consider the in-house prod time, the GR processing time and planned delivery time?

Hi,
Basic scheduling :
1.Basic dates are calculated.
2.Exact to day.
3.No cap reqmts are generated.
4.uses the inhouse production time from material master.
5.carried out automatically during planning run.
In basic date calculation ( order start date/ order finish date ) the system always
calculates backward scheduling.
1. From the reqmts date the system subtracts the GR processing time to
calculate the order fininsh date.
2. From the order finish date the system subtracts the inhouse production time to calculate the order start date.
3. From the order start date the system subtracts the opening period given in scheduling margin key to calculate the order opening date.
Lead time scheduling :
1.Exact to second
2.ie production start date /time and finish date and time are calculated.
3. cap reqmts are generated.
4. uses times from routing.
5. carried out only if the scheduling mode in MD02 screen is kept with indicator 2.
From the order finish date the system subtracts the float after production to calculate the production finish date.
From the production finish date the individual operations in the routing are scheduled backwards to calculate production start date.
From the production start date the system subtracts the float before production
to calculate order start date.

Hi
For FG , by default system does backward scheduling . So if your requirement date is 30 of July then it will go back to determine order start date . It will add GR processing time + In house production time + opening period from sch margin key .
Inhouse prod time is generally lot size dependent and you can to update it from routing also .
For ROH its addition of Planned delivery time + GR processing time + purchasing dept processing time .

Hi,
For SFG, FG system will consider
Opening period+ Inhouse prod time + GR processing time.
For Raw material system will consider,
Opening period+ Procurement time + Planned delivery time + GR processing time

Hi,
System will consider, GR Processing Time + Inhouse production Time for E Materials.
Opening period can be take from Scheduling Margin Key.
