Rescheduling of Maintenance Plan
IP11U
IP11U is a transaction code used for Rescheduling of Maintenance Plans in SAP.
When changing cycle parameters in IP11, there is an option to create Worklist which then will lock the Maintenance Plan for any changes or processing including IP10 or IP30H. IP11U will be used to perform the Rescheduling.
Strategy “Z”
note
Call Horizon 1 day
Note,
Package
1M, 3M, 12M
new Task List “TL2”
with
new Strategy “Z”
3 Operations each for the Packages 1M, 3M, 12M
3 Operations each for the Packages 1M, 3M, 12M
Create new Maintenance Plan
for the Strategy Z
The new Task List “TL2”
1M, 3M, 12M
from
Strategy “Z”
Call Horizine and Date determination from the Strategy when the MP is first created
new
Maintenance Plan
91 is created
use IP10 to schedule in (IP30H also possible)
As usual based on the 1M, 3M, 12M Strategy “Z”
Call Horizon
1 Day
check Scheduling result in
report IP24
as per IP10 results
change
3M to 6M
change
3M to 6M
try to also change Call Horizon from 1 day to 2 day
BUT
the change in this screen do not seem to change the existing Maint.Plan
for the first change, let’s
set “YES” to setup a worklist
note Message that the Strategy is locked for further changes (due to the “YES” to setup Worklist)
note Message that the Strategy is locked for further changes (due to the “YES” to setup Worklist)
due to the “YES” to setup Worklist when SAVING the changes, the Strategy is now locked from further changes.
Run IP11 again, and still the SAME (no changes allowed)
Run IP11 again, and still the SAME (no changes allowed)
IP02 also not allowed change to the Maint.Plan
In fact both IP10 and IP30H are also no longer allowed for the Maint.Plan until IP11U Rescheduling is executed for this any Maint.Plan assigned to Strategy “Z”
only when set “YES” at SAVING changes to IP11 that the Rescheduling via IP11U is allowed!
System generate only Maint.Plan 91 in this worklist as it only found ONE M.Plan assigned with Strategy “Z” that required Rescheduling!
Maint.Plan 91 Rescheduled and removed from the Worklist.
whether IP10 or IP24 will be showing the same result.
After IP11U Rescheduling, check if the Maint.Plan is unlocked
Maint.Plan is unlocked and the new cycle
1M, 6M, 12M was updated to the Maint.Plan
Note Call Horizon is NOT changed
Changes in this screen do not update existing Maint.Plan data
Release Call# 1 to Maint.Order
check the Called Object which is a Maint.Order
Maint.Order called
We already checked earlier that changing data in this screen will not affect Existing Maint.Plan
But let’s change from
1M, 6M, 12M
to
1M, 2M, 12M
and SAVE
BUT this time, “NO” to setup a worklist when try to SAVE the changes in the Strategy
Data changed to the Strategy and
IP11 is NOT locked
IP02 is allowed (not locked) and note cycle is updated
as expected the Call Horizon is NOT changed
try to Reschedule the Maint.Plan using IP11U
no Object (no Maint.Plan) found because Worklist
is not generated
For this case of without Worklist, the affected Maint.Plan can be rescheduled via IP10 or IP30H
New Schedule
Simulate another change to the Strategy from
1M, 2M, 12M
to
2M, 4M, 12M
Simulate another change to the Strategy from
1M, 2M, 12M
to
2M, 4M, 12M
This time “YES” again to create a Worklist
with Set Worklist option as YES, as expected,
the Strategy is locked for further changes until the Maint.Plan affected in the Worklist are Rescheduled via IP11U.
IP02,
change Maint.Plan
not allowed
IP10,
Maint.Plan Scheduling
NOT allowed
IP30H also
NOT allowed
Only IP11U allowed for Rescheduling to the affected Maint.Plans
affected Maint.Plans in the Worklist to be Rescheduled
Done
after IP11U completed,
Maint.Plan is unlocked for changes in IP02
note the latest
Strategy cycles updated to the Maint.Plan
IP11U Rescheduling results
with the new cycle of
2M, 4M, 12M
Since the Worklist is cleared in IP11U for Strategy “Z”, the Strategy is unlocked for changes
IP10 also is not accessible for the Maint.Plan
