Preventive Maintenance date calculation

HI,
I am having a counter with 161 KM.
Annual Estimate is 20000.
Start date for plan is 04.11.2010.
I want to take maintenance for 1000KM. Now the reading is 161 KM.
After scheduling in IP10, the system calculates
Next planned counter reading as 1161
and
Plan date is 13.11.2010.
Can you please explain how it was calculated ?
Thanks.

Hi,
Create the Measuring Point as Counter & assign Annual Estimate 20000. Then create Single Cycle Plan with 1000 as Cycle count & assign the counter in that plan. Also Assign the Single cycle plan & Counter in Equipment.
If you plan the Single Cycle Plan with "0" as start of the cycle in IP10, It will give the the Next Planned Counter Reading as 1000.
If you start with 161, it will give the Next Planned Counter Reading as 1161.
In my example, my start date is 09.11.2010. Annual Estimate is 20000. Validity of the plan is 365 days.
So per day value is 20000 / 365 = 54.79452055. Single Cycle plan value is 1000. Counter reading is 161.
So 1000 - 161 = 839.
Then 839 / 54.79452055 = 15.31175
So next plan date would be 24.11.2010 (i.e., 09.11.2010 + 15).
I hope you will be clear.

Maheswaran.

Changing basic finish date in Preventive maintenance orders

Hi Experts,
My requirement is to block PP work centre when maintenance schedule the equipment for preventive maintenance. I am making system condition as zero in generated preventive maintenance order but basic finish date is not changing in the order automatically. Can anybody please explain how to bring this? Finally my requirement is system should change basic finish date and time as time given in operation of task list.
Thanks in advance.
best regards,
Srinivas M

Hi Praveen,
I have done all setting and tested but there is no change.
My client requirement is like this - whenever maintenance plans are scheduled, for the scheduled dates, production capacity should not be considered by production. We could do this for breakdown orders but not happening for PM orders unless we change the finish date.
The issue is to get the finish date automatically when scheduling maint.plans with respect to values given in operations. Please suggest how to get the basic finish dates automatically.
best regards,

Preventive maintenance order actual completion time and date

Hey gurus,
In preventive maintenance order the basic and scheduled start dates are picked from the maintenance plan. Now the actual start and end dates are in display mode. My client wants an overall completion time and date of the preventive order and not of individual operations. Also at the end of the month they want to see the total time spent on preventive maintenance. Can you suggest any way to sort out the above problem.
Regards,
Abhishek

hi.
the basic start date and end date is coming from maintenance plan. but you can change that dates according to your requirment. For that you have to remove the automatic schduling check in the dates header in maintenance order. Afetr that you can put basic start and end dates as per your requirement.
Also the actual start and end dates and coming when you confirm the operation.
When you confirm the first operation, that date the system will take as actual start date and the day you confirm you last operation or fully confirmed the order will be taken as actual end date.
So i dont think yu have any problem. You can take basic start or basic end dates for this and change the dates as per your maintenace requirments.

Scheduled date in preventive maintenance

Hello ,
A preventive maintenance order has been created by a maintenance plan using strategy (maintenance package) : task list has 3 operations , each has 1 hour of work duration.
In the order, at operation level , in scheduled date , i do not have 1h of work duration but 1h06.
For 1rst operation :"earliest scheduled start = 07:00:00" and "earliest scheduled finish = 08:06:00"
2nd operation : "earliest scheduled start = 08:06:00" and "earliest scheduled finish = 09:12:00"
3rd operation : "earliest scheduled start = 09:12:00" and "earliest scheduled finish = 10:18:00"
I checked work center, task list, ... but i can not see where it comes from....
Someone has an idea?
Thanks,
Pete

hi
While defining the capacity for the workcenter ,i think you have defined the Length of the break ,system will also consider the same for scheduling .kindly check .which is be distributed evenly on the eintire working works
supoose you have defined the capacity starts from 8.00 AM and ends on 17:00 hrs with 100% utilization ,length of the break is 1:00 hr
then effective operating time is 8:00 hrs only remaining 1 hour will be distributed to the total available hours .Hence if you put 1 hr in the operation system will calculate the strat time as 8:00 AM and end time as 9:07:30 ie ( 1 hr/8 hrs =7.5min for each hour)

User exit IPRM0002 for preventive maintenance

user exit IPRM0002 for preventive maintenance
has anyone used this user exit? or BADI: BAdI: IPRM_MCP_SCHE_CHANGE ?
I seem to have some difficulty in knowing how to use these....
I need to basically be able to influence a calling date for next PMorder to be opened but documentation is not explanatory and, even if I do know what these exit/badi are used for, i do not understand how to use the parameters provided.
can anyone help?

Hi,
I dont think you would be able to test the exit if you dont implement them for the user exits simply passing the parameters wont help,actually there is a process of implementing a USER-EXIT i suppose u would already be familiar to it, I order to activate the exit you have to create a project in CMOD transaction and assign the enhancement to that and then also create the include that is avaliable inside the FM and there you would be able to put your code.
For the BAPIs ,yes the control should go inside the BADI once you put a breakd point inside the right method but there to you need to implement the BADI and then you can put your code in the method for the effects to take place and you can test.
The detail process of implementation are already avaliable on SCN, It seems that you dont have developer authorizations so i would suggest to take help from some one who has, Best of Luck:).

Doubt in Scheduling of performance based preventive maintenance

Dear Experts ,
This is with respect to scheduling of performance based preventive maintenance.
I will put my doubt in example so that it will be easy for you to understand.
I want to perform a preventive maintenance for every 100 litres of fuel consumption.
annual estimate is 7200 litres , that means 5 litres a day.
so as per plan , for every day 5 days , maintenance needs to be performed.
same will be appear after scheduling in ip10 also.
While updating in the measuring document , I know that , if 100 litres is updated before due date , then order will be generated in the current date itself.
I just want to know how system responds , if 100 litres consumption takes more than 5 days , will the system generates order as per schedule date or will it wait to complete for 100 litres consumption ??
Regards
Keerthan Kumar

Greetings Keerthan,
That depends on:
1) The frequency that you input Measurement Documents in
2) Your Call Horizon on the Maintenance Plans
3) Your Scheduling Period in your IP30 Deadline Monitoring variant
Generally, SAP will adjust the schedule based on the Measurement Documents entered for the counter (1) to account for readings (usage) which are higher or lower than estimated.However, it will NOT reschedule any Orders already called. So to make sure the dates are usually adjusted to your usage, you want frequently input MDs, a high Call Horizon and a short Scheduling Period.
SAP will determine a scheduled due date for the Order based on the Annual Estimate and the readings. So, if the due date is in 5 days and you are on a call horizon of 100% and a Scheduling period of 3 days, for example:
a) if you do not input Measurement Documents from Day 0 onwards, the Order will be generated due for Day 5 when you run the IP30 on Day 2
b) if you input a Measuring Document on Day 1 indicating that less than estimated or no fuel was used, the due date and call date may be pushed into the future and the Order will be generated after Day 2.
c) if you input the MD after Day 2, this Order will already have been called and will not be rescheduled, but subsequent calls might.

Taking wrong cost element in Preventive maintenance.

Hi Pm Gurus,
I am running Preventive maintenance scenario. I have created T/L with External service as control key (PM03) and given description of external service (no service no), entered material group, cost element, price, Purchase group etc. when the call object is generated from the mainteance plan which is assigned with the above task list, i am not able to see the cost element in Maintenance Order external services view, the purchase Requestion is getting generated automatically in the maint order, when opening the PR the account assignment differs from what i given in the T/L. so at the time of settelment it causing error.
Kindly let me know what settings i have to check.
I have already created default profiles for external services, material procurement and assigned to the order type.
Thanks in advance
R. Loganathan

As mentioned in above threads, you can check for cost element in OBYC.
Cost element for External Service will be derived in following ways.
1. Create Default Value profiles for External Procurement
2. If you have maintained material group & valuation class in service master, it will check in OBYC for GBB. Double click that. In the next screen, search for VBR with the valuation class mentioned in service master. Cost element should have been maintained, that will be filled up.
3. If you have not maintained any valuation class in service master & you maintained material group in service master, it will check for valuation class in IMG => Material Management => Purchasing => Material Master => Entry aids for Items without Material Master. In that screen, search for material group which has been in service master. Take that valuation class. Do the same step as in step 2.
4. Neither Material group nor valuation class in service master, do the same as step 2 & for the VBR without valuation class would have been maintained. Cost element will be taken from there.
5. If no data is maintained in above settings, then the cost element will be picked up from task list.

Baseline Date for Due Date Calculation required for S/L indicators

Hello,
Iu2019m facing the following problem
Iu2019m trying to insert an invoice (using a customer master record) but the system blocks me because the field ZFBDT (Baseline Date for Due Date Calculation) is a Required entry.
The strange thing is that if I use a S/L indicators the field is mandatory, if not the date may be defaulted.
I checked in OB41 but there are non differences between Special PK and normal PK.
Any ideas?
Thanks in advance
Alberto

Dear Alberto,
the field "Due On (BSEG-ZFBDT)" cannot be controlled with field status.
It is controlled by field attribute of screen painter (Tcd: SE51). If
you look at element attribute for "Due On" field, a flag for required
entry is activated. In this case, field status has no control over
the field.
As of release 3.1G, field BSEG-ZFBDT is hardcoded in most FI screens
to be mandatory and cannot be influenced by any field status
changes. This situation is only valid when posting with special G/L
indicator (ie PK 29/39).
SAP development team has determined that this is a critical field. The
reason behind this is that this special GL screen and the data entered
here are very important to many other programs. This data affects
liabilities and receivables where due date is necessary almost
everytime. Thus, we changed this field in this screen in order to
prevent problems in many other areas. The reason is explained further
in note 95079.
I hope this helps You.

Vivek Deshpande

Hi Vivek,
Not sure on clearly what u need .. but have a look at some of the plans and examples of their usage for better idea ..
1. Types : Time Based or Performance Based
2. Single Cycle Plan [Time Based] : Ex u2013 Maintenance of a Vehicle every 03 months
3.Single Cycle Plan [Performance Based] :Ex- Maintenance of a Vehicle every                                1000KM .
4.Strategy Cycle Plan [Time Based] : Ex- Maintenance of a Vehicle every 03                                            months, 06 months etc.
5.Strategy Cycle Plan [Performance Based Plans] : Ex u2013Maintenance of Vehicle                                                                          every 1000km , 2000km etc.
6.Multiple Cycle Plan with single cycle set [Time or Performance Based] : Ex u2013                                                    Maintenance of a vehicle every 3months or                                  500km
7.Multiple Cycle Plan with Multiple Cycle Sets [Time of Performance Based] : Ex- Maintenance of a Vehicle every 3months or 500km and 6months or 1000km
8. The above given are explained with callobject as Maintenance Order. For getting inspection Lot then you can use order type PM05 calibration order in your Maintenance Plan and MO gets created as per the plan cycle and inspection lot gets created once u release the MO ..
9. If you want MP related to service items then create MP with service procurement as Maintenance plan category in IP41 .. for remaining you can put MO as Maintenance plan category .. for details refer to SAP Help ..

Preventive Maintenance Order

Hi Experts,
I want to know about Preventive Maintenance,
The Case is I run schedulle preventive maintenance August 3, 2011 call date August 3, 2011 and the order will automatic created on August 3, 2011
my question is system status on order preventive maintenance always Release (REL) or not?
Thanks for the answer
Best Regrads,
Bernardus Jalu

IMG => PM & CS => Maintenance & Service Processing => Maintenance & Service Orders => Functions & Settings => Configure Order types (OIOA)
In that, for order type, check the check box release immediately. That too will work only in IP30 (Automatic Scheduling). In IP10, release should be done manually.

PM & PP integration during preventive maintenance

Dear Experts,
Once maintenance dept . will schedule preventive maintenance plan for a machine for a year , is it possible to block production order or to show capacity load in CM29 on the maintenance date?? I have assigned PP work center in the equipment & also put system condiiton as zero in maintenance plan & also in task list. Frequency of the maintenance plan is 1 month.Request your help on this.Thanks in advance.

rajib

Hi,
Let clear one thing that the Equipement is work center for the PP and for Plant maintenance it is equipment only.When creating order or plan some maintenance work on that equipement which workcenter for the PP. In PP module ther is standard functionality Capacity planning of work center in Routing when your maintenance work is going on that equipement then work center capacity get reduced due to your maintenace work which will reflect in PP capacity planning. according that reduced capacity planning production order release.there is no std functinality that you can intimate the PP that your work center is in maintenance not use it. it will reflect in capacity planning of PP routing.According that reduced capacity PP plan the production scheduling.and Production work will get adjusted or deayed according available capicity of PP work center.

To track the preventive maintenance work on the equipment itself

Hi Experts,
I have working on the requirement to track the preventive maintenance work on the equipment master data it self.
I have thought of following way of doing it.
1. Create a charateristic "Plan no" having refrence to maintenance plan table & field (MHIS - WARPL)
2. Create a charaterisic "Last completion date" having refrence to maintenance plan table & last date completion field (MHIS - LRMDT)
3.combine these two charateristic in class say "Inspection data"
4.Assign this class to equipment in classification tab
5. Create a maintenance plan , generate order and complete the order.
6. After doing this, these data should updated in charateristic values as given above. But it is not happening.
Am i missing something here. Or can you suggest me other way of doing this.
Regards,
Amar

Hi,
yes you are right we can use object information key and can navigate to required detail.
But the client want the report in a tabular format.
like Equipment no Last testing done on Maintenance plan no
There is one report in classification system that is CL30N in which you can find this kind of report provided the "Last Testing done on " and "maintenance plan no" you have used as charateristics.

Amar

Consider preventive maintenance schedule into PP order capacity planning

Hi PP experts,
My client's requirement is that when a preventive maintenance order is created in PM module for a particular work center (used in production) on a given date, NO production order (which is processed on that work center) should get released or confirmed. In other words, the capacity should be blocked at all for the subject work center.
Could you please guide how to make this effective?
We are using discrete manufacturing with capacity planning. At the time of PP order release, system shows capacity situation so as to decide whether go-ahead even with overloaded capacity.
Regards,
HKV...

First, you should assign the PP work center in the location tab of the PM equipment which refers this workcenter.
Secondly you should enter the sytem condition in the task list of the equipment.
During preventive schedule the work center will be reserved by PM orders for maintenance and this can be seen from capacity planning from PP side.
