How to Automatic update of Measurement Point “Annual Estimate “field based off of average run hours. ?

[Former Member]

Experts,

  When equipments are going into storage and when the measurement documents are not entered SAP generates maintenance plans based on the annual estimate. So was thinking about automatically update the annual estimate based on the previous measurement documents created.

Is there any other way to do it or a better solution?

Thanks,

Hello Raneetha,

According to me, it is definitely a development of a program which needs to be run in background with a frequency (like monthly) at which you want to update the field.  About what this program will have is:

• It will first calculate Annual estimate based on the last month Documents
• It then will update the Annual estimate field either through a suitable function module or through BDC program.

Bottom-line is looks possible without much difficulty. Your ABAPer should be able to do it with these inputs.

Hello,

Thanks a lot for the answer. that is exactly what we are planning right now.

But is not there any other standard way to stop the maintenance calls when there is no measurement documents being created ( ex: within last month)?

Thanks,

Raneetha.

For this you might have to make use of user-exits IPRM0002 or  IPRM0005.

Raneetha,

I did this for a previous client in a very similar way to Paul's link above. We decided NOT to automatically update the annual estimate as it was too risky and may have a large impact on maintenance plan scheduling. Instead the "trained" user reviewed the data and was able to make an informed decision before updating the relevant measurement points.

Here's some considerations to think about when automatically determining the annual estimate:

• Exclude cancelled measurements
• Include a tolerance to exclude excessively high/low values
• Look at an average of values (or last X number of records)
• Are there any measurement points that should be excluded
• Think about what you do if there are insufficient measurements to make a valid change
• How to capture exceptions

If we calculate average couner readings and update annual estimate and than create calls based on same counters, than chances are that results may come up almost similar to time based maintenance. I think some time annual estimate in future could be differant from past trends so I would recomend that one should ensure that some one reviewes calculated value and potential resultant calls before automatic updates. 

Annual estimate should be based on projected opeational use for your equipment. Spare equipments should be based on % utilization of these spares. % utilization of spare part could be based on reliability of operational equipment.

Sounds like you need to develop something similar to this:
