Maintenance Plan Scheduling

[Former Member]

Dear All,

What is the significance of shift factors and tolrences in maintenance planning...

My client requirement is for weekly maintenance plan

plan date is : 18.09.2008 call date :18.09.2008

next plan date:25.09.2008 call date : 25.09.2008

but he has completed the first call object on 23.09.2005 that is variance is 5 days

so next planned date should adjust according to completion date..that is 23.09.2008 when he reshedule the plan..

.How to adjust shift factors to acheive the same...

Regards

Johnson,

Set both tolerances to zero and both shift factors to 100%.

This should give the response you require.

Dear all

In this case if we are maintained shift factor as well as tolerance is 100% , what will be the impact?

I have understand and doing with shift factor . why the sap has provided tolernces also

Dear thenna ,

Tollerence is provided to avoid any shift for the next call if early or late completion of the previous call fall within the tollerence range.

For ex- shortest cycle of maint plan is 30days, U provided shift factor 100% and tollerence 10%. In this case If u do the completion of last call within the 3days of the planned date of the call object then there will be no shift in the next call and if u do the completion of last call more than the 3days (suppose 5days) then the next call object will be shifted by 5days bcoz u have given the shift factor 100%.

Hope u understand.

Guys,

If I had flagged the completion requirement option in maintenace plan and specify shif factor as 100% ..will the dates will get adjusted if there is a delay in completing the task. or we need to unflag the completion requirement to adjust the dates ?

ex lets say its monthy package and first work order created on 01.01.2008 and it is completed only on 01.15.2008 tht is 15 days late...so automatically next cycle shd be 02.15.2008 instead of 02.01.2008 as I mentioned shift factor as 100%...in this case do we need to flag the completion requirement or not ?

Dear Vijay,

As per ur example u don't need to select completion requierment, only maintain the shift factor if there is any delay in the completion of the order then next order will be shifted for the same no. days if shift factor is 100%.

Dear,

The shift factor only applies once the maintenance plan has already been scheduled, and when the difference between the planned date and actual date lies outside the tolerance range.

hi

The shift factor in the event of late completion of a maintenance task defines the percentage of the shift to be applied to the calculation of the next date.

It is only applied when the variance between target and actual date is outside the tolerance range.

so you use 100% so when ever you schedule is delayed the dates are pushed.

ex your order is asper plan on 01.08.08. but you completed it on 01.09.08. so if you use the shift factor 100% the next dat is on 01.10.08 (if the plan is monthly)

hi

i think you can make use of completion requirement on the maintenance plan itself
