OEE(Overall equipment efficiency)Report

[former_member221041]

Dear All,

I am working in discrete manufacturing with make to stock & planning strategy(40) by creating production orders through co01 & confirmations by co11n.I want to track OEE for shopwise.Is there any standard report or programme in SAP to get this report.A customized report is already in place in which i have created some ztables in co11n to record downtime & available time but due to some reasons the report is not giving appropriate results.

Regards

Hi,

Please check with MCP1 : Operation Analysis Selection,

MCP7 : Work Center Analysis Selection,

MCPD MCPU Production order analysis.

But for efficiency you need go for Z development only.

Thanks For Reply ,

Can you suggest some zdevelopment for this report.

Hi,

Overall equipment effectiveness (OEE) %

o OEE = availability *performance *efficiency

u2022 Yield %

o Yield = actual good quantity produced/total quantity produced

u2022 Performance%

o Actual quantity produced/planned target quantity

u2022 Availability %

o Production time/total time

All these value you will get in CO11N and work center.

Select Plant from the value help.

Select Date Range for which you are interested to see the report. Find the relevent field and table along with technical consultant and go ahead.

Dear Brahmankar,

Thanks,

I have told you already that i have configured these availability,performance,quality factors in my customized report but the problem comes when the users do not put actual breakdown(m/c's) times,downtimes(other reasons such as material shortages ,set ups,man power non avilability etc.) & do not put/change the actual start & end times in the co11n confirmations resulting in improper OEE rate some times go very high & some times go down i.e.why i am asking for some standard SAP report.

Hi,

There is no such report is available in standard SAP for calculating efficiency report for orders. We have to do standard analysis by z development only as earlier I told you.

Machine down time can be obtained in PM module only.

That way machine efficiency can be obtained from the utilized time from CO11N & machine down time from PM Module.

Please refer this thread,

Hope clear to you.

I am currently working in discrete manufacturing with a Make-to-Stock (MTS) strategy, utilizing Planning Strategy (40) in SAP. My production orders are created using transaction CO01, and confirmations are performed through CO11N. I’m looking to track the Overall Equipment Effectiveness (OEE) on a shopwise basis.

I have a customized report in place where I’ve created some Z-tables in CO11N to record downtime and available time for each work center. However, despite these customizations, the report does not provide accurate results as expected, and I’m seeking a more effective solution.

I came across a comprehensive guide on Understanding OEE - The Key to Manufacturing Efficiency on INS3 , which outlines the importance of tracking OEE in discrete manufacturing, focusing on the following core factors:

1. Availability: Measures whether the equipment is available when required for production.
2. Performance: Evaluates the actual output against the maximum possible output.
3. Quality: Tracks the ratio of good parts produced versus total parts produced.

These three factors combined help to calculate OEE, which is crucial for understanding production efficiency.

Current Setup and Challenges:

In our customized solution, I have created Z-tables in CO11N to track downtime (for unplanned stoppages) and available time (for total operating time). While this solution covers some aspects of OEE, the reports generated do not seem to provide accurate or comprehensive data on OEE per shop floor. The discrepancies might be due to missing or incorrect data entries, or an issue with how downtime or availability is being calculated and tracked in the system.

Standard SAP Solution for OEE:

To address the gaps in my current customized solution, I wanted to explore standard SAP solutions for tracking OEE, as I believe this might help optimize the process. Some potential areas I’m considering:

1. SAP Manufacturing Execution (SAP ME): SAP ME provides an end-to-end solution for real-time production monitoring, including OEE tracking at the shop-floor level. It can automatically capture data from machines and work centers, eliminating the need for manual data entry. The system tracks downtime, production performance, and quality metrics, offering a more accurate representation of OEE.

2. SAP Plant Maintenance (PM) and SAP PM Integration with CO: If your system integrates Plant Maintenance (PM) with Production Planning (CO), you can track downtime at a granular level (such as machine breakdowns or maintenance activities). PM notifications can feed into CO11N and production orders to monitor and report OEE efficiently.

3. SAP Advanced Planning and Optimization (APO): In some cases, integrating SAP APO for demand planning can provide better insights into how machine performance affects supply chain targets, enhancing the accuracy of OEE data at the shop floor.

4. Standard OEE Reports in SAP:

   • SAP provides some standard reports and queries for performance monitoring that can be customized to a certain degree.
   • For example, COHV (Order Confirmation Overview) can provide insights into order statuses, and by enhancing this with downtime and performance data, OEE metrics could be tracked.
   • Alternatively, transaction KOC1 (Production Order Confirmation) can also offer confirmation data, and integrating this with downtime records can potentially yield the OEE metrics you're aiming for.

5. Custom OEE Report with SAP Query or ABAP Development: In cases where standard reports are not sufficient, you can extend SAP functionality by developing custom reports using SAP Query or ABAP. This could help you incorporate additional data points, such as:

   • Planned vs. Actual Production Time (Availability)
   • Cycle Time vs. Actual Cycle Time (Performance)
   • Scrap or Rework Rate (Quality)

Suggested Action Plan:

1. Audit the Current Z-tables: Review the logic behind the custom Z-tables for downtime and availability. Ensure that the data is accurately captured and classified (e.g., distinguishing between planned maintenance vs. unplanned downtime).

2. Check Integration with CO and PM: Ensure that downtime information from PM notifications (if used) is correctly linked to CO11N confirmations. This will help provide accurate data for OEE calculations.

3. Leverage SAP ME or AP: If possible, integrate with SAP ME to automate the tracking of equipment status and performance. Alternatively, APO can provide valuable insights if the system is integrated.

4. Develop Custom OEE Reports: If standard reports fall short, working with an ABAP developer or SAP consultant to develop a custom OEE report could be a more effective solution. This could integrate all relevant data sources and provide shopwise OEE performance metrics.

In conclusion, achieving accurate OEE tracking in SAP requires a holistic approach, integrating downtime, performance, and quality data at the shop-floor level. Standard SAP modules like SAP ME, PM, and CO can be utilized to improve this tracking. Custom ABAP development or SAP Query may be necessary if current solutions are insufficient.

I hope this insight helps you refine your approach to tracking OEE efficiently in your SAP system.

Thanks.
