Dear Yadav,

As per the scheduling parameters given to OPU5 (for plan orders) scheduling takes place in MRP

There are two types of Schedulings

1) basic date scheduling

2) lead time scheduling

basic date scheduling - in initial parameters of MRP if u give scheduling as basic scheduling then system takes the data from material master i.e in-house production time. in this scheduling capacity requirments are not generated

lead time scheduling - in initial parameters of MRP if u give scheduling as lead time scheduling then system takes data from Routing to calculate dates. here cacity requirments are generated.

Coming to dates

if ur maiantaing in-house production time as 2 days for FERT & 2 days as plan delevery time (without GR processing Time)

Then system does backward scheduling as (if u maintain backward scheduling in OPU5)

so total days for FERT to be availble will be 18.07.2009 (starting from today)

Regards

kumar
