The planning run continually changes the overall delivery schedule for a scheduling agreement as a result of new or changed material requirements (e.g. dependent requirements). The quantities and dates in the current schedule stored in the system thus directly reflect current requirements of materials. Snapshots of the current overall schedule are transmitted to the vendor as SA releases (FRC or JIT schedules).
The purpose of using SA releases is for the desired quantities of the relevant materials to be delivered on the dates they are required.
Requirements with regard to delivery and production lead times in connection with procurement via scheduling agreements are usually addressed as follows: The vendor first receives forecasts enabling him to plan and initiate his procurement and production operations. Subsequently, a more detailed breakdown is provided, showing the exact quantities required by the buying entity plus the corresponding delivery dates.
You send the vendor scheduling agreement release in the form of a forecast delivery schedule, advising him how many tons of the material Steel 1 you are likely to need over the next nine months: e.g. 1000 tons in January, 900 in February, etc. You then specify the exact dates and quantities in a JIT delivery schedule (the second form of SA release). For example you need 30 tons of Steel 1 on 10 January, 20 tons on 14 January, etc.
Prerequisites
SAP recommends the following settings:
- 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).
- If you wish to work with JIT schedules, set the JIT delivery schedule indicator in the Purchasing view.
- 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:
a) 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 the plant parameters under External procurement in Customizing for Materials Planning.
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.
b) 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)
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 indicator to 3 as a general precondition for the generation of delivery schedule lines under scheduling agreements.
- Start in past
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.
