Maintenance History of Multiple Equipments

We are having one equipment as reference object in maintenance order.  My client want multiple equipment in reference object in maintenance order so that we can reduce the number of orders and we can assign components to multiple equipments separately.

Answer:

No, it is not possible to have the multiple equipment in reference object screen. But you can put all related equipment into object list of the orders.

Disadvantage of this is while viewing equipment history you cannot view that order for the equipment which are assigned in object list.

You can only display the order in the history of equipment which is assigned in reference object screen.

For reducing maintenance orders per reference object you can use object list.

The object list does not control the order-no adjustment of work to be performed, update of history or cost distribution will take place.

You can use customer exit IWO10027 to distribute the order cost proportionately to objects in the object list.

According to my knowledge, you can get Maintenance history of Multiple equipments assigned in object list & Order without any User Exit.

You have to run IW37N or IW38 , Check Mark "incl Object List " & input Equipments Number Range you will find the Order & Equipments included in Object List.

For distributing Cost to Equipments in Object List You need to use User Exits. 

One More disadvantage of using Object List is even I do Assignment of Equipment in Object List to Each Operation in Order & I book Some Materials in each Operation, I Cannot find this Report in IW13 or S_ALR_87013434 - Material Where-Used List . 

This Material Reports Works only for Main Header Equipment. 

I would suggest go for Object List only if are Working with Group of Equipments Carrying Same Operations where Cost Booking is not so important but you need Maintenance History.

For Ex , Lubrication of All Pumps , Calibration of No equipments , Check of Oil Level in Gearboxes , Lubricating Motors bearings , Checking of Temperature gauges where you need ensure Maintenance is done for All equipments.

Even if you want to Distribute Cost Proportionately you can use Object List , for Example I have Calibrated 10 Equipments using One Maintenance Order , with 10 Equipments in Object List , Cost of Calibration is 1000 Rs , So Cost of Calibration of Each Equipments is 100 Rs or 10% of Total Cost , I Settlement Rule I can mention this 10% & I can pass this to individual equipments easily ,

Take Other case One Equipment have Costed me 70 Rs , Other Equipment 130 Rs who is going to sit & calculate the Percentage Cost Share of Each equipments.

For Overhauling of particular pump or during shutdown or major overhauling better Use Order & Sub Order for Easy Cost Capturing & Maintenance History.
