    One exercise you can ask your people to do,

    Ask them to go to MD05 / MD06 transaction and there you can generate report MRP controller wise.

    You can ask them to go through each exception message for the MRP list and ask to understand the problem and resolve it. And whenever they are able to understand the analysis and resolve it they can set processing indicator for that.

    Next time they can put filter on unprocessed indicator and try to solve them. By this you can make to attempt to resolve the MRP exceptions and people will become more aware of MRP result.

    Material Requirements Planning (MRP) enables you to plan material requirements for a manufacturing or procurement process.

    MRP calculates gross requirements for the highest Bill of Materials level based on sales orders and independent demands. It calculates gross requirements at the lowest Bill of Materials levels by carrying down net parent demands through the Bill of Materials structure.

    The results of the MRP run are recommendations that fulfill gross requirements by taking into consideration the existing stock levels and existing purchase and production orders. The MRP run also takes into account defined planning rules for Order Multiple, Order Interval, and Minimum Order Quantity.

      you are right, thats exactly what is going on in our company.

      the master data are all set very close to current business situation.

      the problem is, i cant figure out if they really take care of MRP result and adjust accordingly.

      the situation is, whenever i ask them " have you run MRP?" they would go, "yeah we did", but i dont quite trust them at the moment, while i dont have any evidence to say that they are not doing it well either..

      anyway, thanks for sharing, cos now i know im not the only one facing this problem.

    I can understand your concern here. I was in a similar situation once. It will take a consolidated effor from SAP team and business team to stabilize MRP in an organisation.

    First you will need to undertand the pain areas with the buyes for not using MRP output, then find out ways to adress those pain areas. Also build some checks in the system to and physical process to follow the planning stages of the organization as whole. Please see the below text to have an idea what i did to counter the similar situtaion

    Pain Areas after survey of buyers and production


    1. Schedules as per MRP are not correct, schedule lines and purchase requistion generated by MRP are not as per what needs to be followed

    2. General persption data in SAP is not correct, lot of last minute chnages required to be done to keep factory running


    1. Planned orders in the system are not as per there requirement

    based on the surver following strategy was designed

    MRP stabilization in 4 steps

    1. Plan

    Check Master Data

    Production Planning

    Purchase Planning

    2. DO

    Production Execution

    Purchase Execution

    3. Check

    Check Planning and Execution Results( Plan Vs Actual for sales/production and purchase)

    4. ACT

    Act on results and modify master data and planning data to get desired results through system.

    Detailed presentation was prepared and user education drive was done to percolate this.

    Following system and busness checks where introduced

    1. buyer needs PR/PO/Schedule lines to purchase material

    manual creation of purchase requistion was not allowed

    PO cannot be created with out purchase requition

    Schedule lines cannot be added to schduling agreement manually

    If there is urgent need then it was given to plant head or procument head to manually change the quantites in the POs and schule lines.

    Few custom reports were created for buyers

    one of the reports which was very useful was plan Vs Actual purchase

    there are standard reports to get this data but they are usualy one material at a time or time axis in vertical

    it was like below, you can be inovative here. idea is to make the user comfertable.

    T1 T2 T3





    normal produre was to run through the PDCA steps defined adove to get correct schedule.

    This plan was rolled out in fractions by grouping a group of buyers. Aslo a report was creted to highligh manual VS MRP purchase documents and it was made one of the factors in performace of the buyer.

    Thus it was a mix of both change managemt and system changes to strike a balance. In 6 months time they where able to stream line the MRP process with minimal manual interventions.
