Performance based maintenance and updating of measuring points.

[Former Member]

Hi

I have the follwoing problem. I have serveral equipments / measuing points linked to a performance based strategy based on produced items. But because of missing of using (producing items) equipmen for longer periods there is no opdating of measuing points/ creation of measuing documents. But the system IP30 are still creating maintenance orders - based on the calculation of AnnualEstimate in the measuing point. To aviod this SAP standard says we should freq. update the measuig point. But it is not possible to do this (busssineswise)....or at least I have been thinking about the following solution:

1. Create a LSMW for IK11, creating create a measuing document with a diffenrence of zero for all measuing points on the plant.

2. Run IP30

These step should be done freq. (expected every week) in a batchjob.

The number of measuing points are approx: 100. It will normaly be updated thorugh a integration to production orders via PRT.

But i can not figure wheater this will give other problems or just solve the issue.

Another option is to reduce annual estiamte to 1. So if your cycle is say 100 hours, next order will be scheduled after 100 years.

Hope this helps-

I think the best solution here would be to have 'Completion Requirement' selected for these maintenance plans. This will stop at the first maintenance call and will not create any further. So even if you run IP10/IP30, it won't create next call at all.

Hi Ketul

Thx for the answer - but would the system then make the first PM; order still based on the planned dates in IP10/30. And the you still have to control the orders og do I miss something here?

That's correct. It will create the first PM order based on the dates. It will not move further as they have not closed the PM order. If they want to have preventive maintenance - counter based, they need to update the counters, pretty strange.

Hi Ketul

Thanks for your answer and input -but thats my point :-). SAP standard says that I should update the counters frequently to use the performance based as stated in first messages. The counters are based on usage in PRT allocated in production orders, but the time between orders could be so long that, the system create an order before the counters reach the cycle/usage for next maintenance order..

So my idea was to update the counters with a difference of zero every week with a LSMW in a batch job and then schedule a new plan. But can I expect any problems with this method or will it work?

It won't make any difference to the system by having values with zero difference. They would be just measurement documents. System will assume the usage based on average values maintained in measuring points and move ahead.

Essentially for counter based preventive maintenance, when you schedule any plan, system checks the last counter reading and also checks the average consumption values based on the last call or the start date of the cycle (if it is being run for first time). It then identifies the value to be considered for creating the next call.

You need to have the values and the counters updated, whichever way you do it. No other option on this.

I hope this clarifies your doubt.

Hi Woer,

As youe mentioned you are not using the equipments for longer duration then why dont you make it Inactive, so that referenec to this sstatus you can prevent the Plan to generate the order.

Just see if this solve your purpose.

Thanks,
