Pre requisite to set for Schedule Agreement release for JIT (JIT schedule)
Prerequisites
Below setting are required
- Material Master Record
- Deterministic planning procedure (e.g. PD).
- Exact lot-size calculation (e.g. EX).
- Separate MRP group for materials you wish to procure by means of scheduling agreement releases (see below: MRP Group for Materials Ordered via SA Releases).
- Choose the JIT delivery schedule indicator 1 in the Purchasing view if you want to work with JIT schedules.
- Choose Procurement type F (external procurement) in the MRP 2 view to have scheduling agreement delivery schedule lines generated in materials planning.
- Source List and Quota Arrangement
Create a source list record for each scheduling agreement item and set the indicator for relevance to materials planning to 2. Materials Planning then continually updates the overall delivery schedule.
If you have several scheduling agreements for a material, use the quota arrangement to apportion the requirements among the different vendors.
- Customizing Materials Planning
Plant Parameters
Choose one of the following options in order to have Materials Planning generate schedule lines for scheduling agreement items in accordance with required quantities and dates:
- All time portions of forward scheduling are 0
Set the planned delivery time and the GR processing time to 0 in the Additional data for the scheduling agreement item.
Set the purchasing department processing time to 0 in Customizing for Production under Material Requirements Planning à Plant Parameters à Carry Out Overall Maintenance of Plant Parameters in the Planning Run area under External Procurement.
If the requirement date lies in the past, the system takes the current date (date on which the planning run takes place) as the delivery date. Otherwise, the delivery date corresponds to the requirement date.
- Start date lies in the past
In this case, the system always generates scheduling agreement delivery schedule lines whose delivery dates correspond to the requirement dates because the system never carries out forward scheduling.
You specify in the MRP group that a start date that lies in the past is allowed.
MRP Group (for Materials Ordered via SA Releases)
Maintain the following settings in Customizing for Production under Material Requirements Planning à MRP Groups à Carry Out Overall Maintenance of MRP Groups:
External procurement
- Scheduling/document type
If you set the Sched. info./agmt. indicator, the system adopts the GR processing time and the planned delivery time from the scheduling agreement item for scheduling purposes (see option (a)).
Planning run:
- Creation indicator
Set the SA sched. lines indicator to 3 as a general precondition for the generation of delivery schedule lines under scheduling agreements.
- Start in past
Using the Start in past field, you can also specify that the system is to work with a delivery date that lies in the past (see option b).
Assign this MRP group in the master records of the materials ordered via SA releases
