What is mean by schedule lines? Explain the schedule lines in md02?
1. no schedule lines 2. schedule lines in opening period 3. schedule lines
Schedule lines are created against schedule
agreements. Say if you have a material which is procured from subcontract. If
you want the delivery in particular days with schedule you can maintain schedule
agreeement. In source list you will maintain vendor, schedule agreeement with
validity dates and which agreement is relevant for mrp.
If you maintain 2 against the sch agreemetn mrp will
generate schedule line which you can see in md04. Also this delivery schedules
are updated in scheduling agreement (t cod ME33). When running mrp in initial
screen delivery schedules--you have to maintain 3 create schedule line
Schedule line in opening period - Opening period is
maintained in Configuration of "Schedule Margin Key" which is getting assigned
to Material master in MRP2 view.
Your understanding of the result after MRP is needed.
Define Floats (Scheduling Margin Key)
In this step, you specify the floats for determining
the basic dates of the planned orders. The floats are allocated to the material
via the release period key in the material master record.
The opening period represents the number of workdays
that are subtracted from the order start date in order to determine the order
creation date. This time is used by the MRP controller as a float for converting
planned orders into purchase requisitions or into production orders.
Float before production
The float before production represents the number of
workdays that are planned as a float between the order start date (planned start
date) and the production start date (target start date). On the one hand, this
float is intended to guarantee that delays in staging a material do not delay
the production start. On the other hand, the production dates can be brought
forward by means of the float to cope with capacity bottlenecks.
Float after production
The float after production should provide a float for
the production process to cope with any disruptions so that there is no danger
that the planned finish date will be exceeded. You plan the float after
production between order finish date (planned finish date) and scheduled end
(target finish date).
The release period represents the number of workdays
that are subtracted from the order start date in order to determine the
production order release. The release period is only relevant for production
order management. Recommendation
The opening period should reflect the processing time
the MRP controller needs to convert planned orders into purchase requisitions or
production orders. The opening period should be at least as long as the interval
between two MRP intervals, so that all planned orders can be taken into account
during the conversion.
