Periodic maintenance scenario

Question

I am trying to create the following scenario in SAP (ECC 6.0):
1. We have a number of DG sets of varying capacities feeding power requirements for different areas and functions (operations) of plant (a large petrochemical complex).
2. Maintenance tasks have to be carried out periodically based on manufacturer's recommendations based on hours run or calendar period. For example the "B Check" has to be carried out every 250 hours of actual running hours OR every SIX Months, whichever is earlier?
3. Once the limit is reached the system to generate a maintenance order automatically.
Can you please help me by describing precise sequence of steps that I must follow? I want the system to generate the order on reaching the threshold of SIX months even when the DG set has not been run at all. (I have already crated objects such as FLOC/equip etc.)
Thanks for help.

Answer 1

Hi,
Got delayed again. Fact is I had a small mishap in office and has been diagnosed with a muscle tear. Currently have a nice (precautionary) cast on my right foot.
Just to come back to your reply, my comments are:
1.    I guessed as much. Thanks for confirmation.
2.    I will take you through the steps I am following.
    a.    My primary aim is that the system would create a maintenance order based on the multiple counter plan.
b.    I have completed all the four steps as was suggested by you including assignment of Task List to the multiple counter plan,
c.    The next steps to achieve the objective would be:
c1.    Scheduling of the multiple counter plan (Tcode – IP30). After creating the plan, from the session itself (IP43) I went to Maint. Plan -> Schedule which is basically IP10 and using “Start” button created Scheduling Call. Afterwards using IP30 created Deadline monitoring but I am not sure what effect it is having (other than a log that “Maintenance plan has been scheduled”.
c2.    I understand I have to create measuring documents periodically so as to update the actual no. of running hours of the DG set (Tcode – IK11) i.e. increase the value of running hours. But after I have created the meas. doc. and on trying to check the new schedule of start of the job I find that instead of advancing the start date it is receding back. Actually during one of such checks the error msg “Release not possible as MaintPlan already released, called or skipped” was received. My point is that if equip. usage has been more than the average value based on the estimated annual value specified in the counter. the scheduled date of the “B Check” should be earlier (i.e. advance). But that am unable comprehend from the scheduling list why it is happening to the contrary. Please guide me on this as to where I am going wrong.
c3.    One question: How does a user check in the system as to the current status of the number of running hours having been completed for the DG set?
c4.    Is there a way that the system generates an alert once it reaches the threshold value (when the actual maintenance i.e. “B Check” has to be carried out)?
c5.    How do I simulate the scenario in the system by inputting the additional running hours done (instead of creating measuring documents)? This will be solely for the purpose of testing if the settings are working as desired.
3.    About the points made by you in your footnote:
    a.    I have created separate Multiple Counter Plans for each DG.
    b.    Could you please elaborate on your following points:
b1.    “You will probably want to have a high Call Horizon on the Maintenance Plans” – What exactly do I need to do for this. Please note that as per my requirements, the maint. job will need to be carried out before the expiry of six calendar months.
    b2.    “You will probably want to have a short Scheduling Interval”. Since I have two parameters in the plan i.e. Running Hours and time based (Month), if I have understood your point correctly, even if no measurement documents are not created in the interim, the system would create an order based on the second parameter (Month) once the value reaches the threshold (i.e. after the Six month period lapses).
    b3.    “This is to avoid a situation where SAP schedules the maintenance based off the Annual Estimate, and the Order is called in advance, but then due to low usage, no new hours are recorded and maintenance should be delayed - but can't be done from the Plan as the Order is already called” – I think this point would be part of the point above i.e. “b2”.
Please let me know if this is in order and the way forward.
Thanks
