PM notification breakdown duration

Hi everyone,
when creating a new maintenance notification (IW21) and not checking Breakdown, the system still automatically calculates breakdown duration?
Can anybody tell me why that is, is it normal and is it possible to change it?
Thanks in advance,
MaryM

Hi,
Entering Breakdown Data and Duration
If there is a functional breakdown due to a problem or the execution of an activity, you note this breakdown - depending on Customizing - in one of the following two places:
Notification header
As a rule, when you create a notification, it is sufficient to enter the malfunction start in the notification header, and flag the field Breakdown. This indicates that the system is broken down at the time specified.
Breakdown data screen
The breakdown data screen is relevant mainly for entering the breakdown end and the downtime.
Entries in the Breakdown Data Screen
Call up the notification in create or change mode and choose the tab pages Malfunction, Breakdown.
Enter the start and end dates of the malfunction. Flag the field Breakdown to indicate that the malfunction caused a function breakdown.
As soon as you press Enter , the system automatically calculates and displays the downtime in hours.
If you want to use a different unit of time, enter it in the field to the right of the field Breakdown duration and choose Enter.
The system calculates and displays the duration in the new unit of time. The unit entered when you save the notification is then valid for further processing of the notification.
Save the notification.
If the downtime is already displayed and you subsequently change the malfunction start or end, the system recalculates the duration.

How to change Unit for Breakdown Duration in Maintenance order.

Hello,
In cuni, somebody created Unit "TST" by mistake, system can not convert it to "second" for calculation automaticlly.
"TST" make no sence. So if maintain "TST" as Unit for Breakdown Duration in a maintenance order, dump will happen. However there is a maintenance order maintained Unit for Breakdown Duration as "TST" saved by mistake, Dump will happen when I try to access to this order by IW32 to change the Unit for Breakdown Duration. Is there any way to change the Unit for Breakdown Duration"TST" to "H" so that I can access to this order by IW32.
Thank you.

Hi,
You could temporarly adjust the CUNI definition for TST so that it can be converted to seconds. Adjust the notifications to set a valid unit of measure.
The alternative would be to update the field MAUEH in table QMIH with a valid breakdown unit of measure.

Modifying the Breakdown Duration with the help of a BAPI

Hi,
I am using BAPI_ALM_NOTIF_DATA_MODIFY to modify a notification. This BAPI allows to modify everything but the Breakdown duration.Any idea why is that? Or is there a workaround?
From a SAP Note it seems for MCI7 - Brekdown Analysis report would show correct results for MTTR & MTBR only if the breakdown duration is properly populated.(thats one of the conditions that should be met.)
Thanks

Hai, Breakdown duration is automatically calculated by SAP based on the malfunction start date & time, Malfunction end date & time entered in the notification.

Changing breakdown duration units in reports

Hi All,
I want to know is there any way we can change the breakdown duration "units" in Reports such as IW29 and IW39.
Actually what is happening is that whenever there is a breakdown for less than 18 seconds, then these reports show breakdown duration as 0.00 Hours.
E.g. for 17 seconds breakdown duration, these reports show 17/3600 = 0.00 Hours and of course this should not happen.
Appreciate your help...
Thanks,
Thushantha

Hi thusantha
For ur Purpose...
Maintain the Unit "Seconds" in SPRO Settings
SAP NetWeaver - General Settings - Check Units of Measurement
U cannot change in list display mode...
If u see in the change mode of the notification, u can change the settings...
I think, seconds is not maintained..
So.. Ask Core team members to customize Seconds.
Normally in SAP it will be maintained in H - Hours. thats why ur getting only Hours...
You can change it into seconds

Basis in computing for breakdown duration

Hi All,
Good afternoon. I would just like to ask as to what is the basis in computing the breakdown duration generated upon completing a breakdown report? Is it standard that it is computed based on 24hrs a day? If it is, is there a way to change it from 24 hrs to 8 hrs per day? Hope you could help me all. Thank you.
Thanks and regards,
Happy

Hello,
The system determines the MTTR and MTBR key figures on the basis of the individual history of a technical object. The MTTR key figure represents the arithmetic average of the downtimes for the object concerned. The MTBR key figure, however, represents the times in which the reference object was fully operational.
To generate these key figures, this system draws on all the malfunction reports with breakdowns that were created since the start-up date of the reference object. For technical objects, for which the start-up date is not specified in the master record, the system uses the end date of the first malfunction report where the breakdown indicator was set as the start date for consideration. In this case, the first malfunction report is not taken into account in further calculations.
In addition, the system only evaluates those malfunction reports for which the start and the end of the breakdown are specified. The evaluation using the start time and the length of the breakdown is not supported.
The system uses the amount of breakdowns reported for a technical object to first determine the effective breakdowns. In doing this, it merges two reported breakdowns that overlap in time. The reference time for assigning the MTTR and MTBR key figures to a statistics period is the start of the effective breakdown. In the case of longer breakdowns, this can make it impossible to calculate the key figures for the subsequent periods.
MTTR = Sum of effective downtimes / Total of effective breakdowns
MTTR = Sum of effective time between / Total of effective breakdowns

How to convert PM Module Breakdown Duration (AUSZT) floating point value into Minutes

Breakdown Duration
1.6100000000000000E+02
Now I want to convert the value '1.6100000000000000E+02' into Minutes.
Kindly let me know the solution.
Note: I tried with standard FM 'PM_TIME_CONVERSION' and converted the break down value into hours.
For example: 1.6100000000000000E+02 to 4,472222222222222E-02.
But i want to convert the break down duration value into perfect minutes.
With Regards,
Sudhir.

Simply equate to a variable of type P decimals zero. It should give you value in seconds. Divide it by 60 to have it in minutes.

Flip (8220) LED notification light duration and control problems

As I've read on the boards with regards to other models, the red LED notification light stops working after exactly 15 minutes. T-mobile customer service was unable to find a way to extend this so that it keeps flashing until I check the message. And so, after consulting the boards, I downloaded the BBAlerts app from handango. But the desktop Manager doesn't pick it up as a suitable app for my device.
Any suggestions?

This is a problem with all BB's! The message lights always revert back to green after a certain amount of time. It was one of my main complaints when I got the curve! I know it's stupid...it makes no sense but you have to complain to BB.

Capturing exact break down duration in a Notification

Hi experts,
My client requirement is like this:
Plant is operating only 2 shifts. i.e. 6 AM to 11 PM (No 3rd shift operations).
Breakdown occurred at 9 PM in the evening and the equipment restarted by 7 AM next day. Notification has been created with these timings...i.e. from 9 PM on the day actual breakdown occurred and next day 7 AM as end time. Now system is proposing breakdown duration as 12 hrs., where as actual breakdown is only 3 hrs, (since the plant is operated in only 2 shifts, even the technicians worked only 3hrs to rectify the problem).
Since SAP is considering 24 hrs , the realistic breakdown times are not being represented.
Please suggest how to handle this i.e. to capture only actual breakdown durations.
Is it necessary to create to different notifications (with 2hrs and one hr duration), because of two different dates, ?
Thanks in advance....
Srinivas

Hi srinivas
Srinivas, when the SAP is implemented, they have designed the SAP Standard timing for 24 hrs. It can be restristed to 16 Hrs with respect to your work hours. So the problem is you cannot reser or create or any work after the 16 hrs. To avoid this kind of issue they have desided to go for 24hrs.
Here comes the problem with the break down. You feel if the break down duration increased, it affects the MTTR.
The break down occured at 9PM, when u create a notification, it takes the malfunction start timing and date which the notification was created or u can enter the accurate timings.
Break down is nothing but the equipment is stopped till the equipment is started. thats the normal timing of the break down. You can change it, if u want to get the accurate MTTR etc...If u manipulate, then only ur MTTR will not increase.
To calculate the exact time of work, you will be comfirming labours work duration in IW41. So, there u can enter the labor worked only for 3 hrs, which means actual cost of the labour. It will be accurate.
If u give the break down duration as 3 hrs. It means rest of the time the system is in idle. Waiting for start.
At last : SAP will calculate for 24hrs, since it was defined. If u change it, it will lead to many problems. So manipulating the hours wil be efficient to get the break down and Confirming the labour timing in IW41, give the accurate work hours. Actual cost of labor.
Hope u understand it

Problem about Notification Order (SAP PM/CS)

I found problem in notification order have unit of breakdown duration is 'H'.
Could you help to find the way for chang to 'Min' unit?
In Notification Order . Can see in 'Malfunction' tab.

Please check the sales area in the notification and the contract.

Short dump will happen because duration time unit is wrong.

Hello,
I maintained breakdown duration time unit as "TST" which is created in CUNI. System can not convert it to "S", so system will dump when I tried to access this maintenance order. So I want to change this time unit "TST" to "S" or "h". I tried to make this change in SE16 table VIQMEL, but failed. Could anybody tell me how to make this change?
Thank you.

Dear Stephen,
have you changed all unit measurement? VIQMEL is table for notification header and you said that you cannot access maintenance order. so, i think you should check table AUFK, AFKO and also AFIH. for unit measurement in order

MTTR/MTBR Breakdown and Machine Failure Time

We create PM Notification with the IW24 where we enter the Breakdown time.
The problem is that we need to monitor the MTTR/MTBR (MCJB, MCJC & MCI7) but only when there is a breakdown because of a malfuction of the machine (machine failure) and not for a non-machine-cause breakdown. We need to register both times (Breakdown, and Machine Failure).
I think that an option is using these 3 scenarios:
    1. If we select the "Breakdown box" it will be a machine failure.
    2. If we not select the "Breakdown box", but there is a quantity on the "Breakdown duration" .. It will represent that there   were a Breakdown.
    3. If we not select the "Breakdown box", but there is NOT a quantity on the "Breakdown duration" .. It will represent that there were NOT a Breakdown.
The problem is that if we use the 3rd scenario, when we save the Notification (or the PM Order) the time disappears.
¿There is an option to save the time even do the "Breakdown box" is not selected?
¿Where can I configurate the PM Notification? ¿Or where can I configurate the MTTR/MTBR (MCJB, MCJC or MCI7)?

Hello
Manzarek     ,
I will suggest you following;
1.Just create different different notification types for all your scenarios.
2.Just select the breakdown vies in the notification type where the actual machine breakdown occurs due to machine failure.
The path for that is
Plant Maintenance and Customer Service->Maintenance and Service Processing->Notification Creation->Notification Types->Define Notification Types
3. You can not directly enter the breakdown time without completion of the same.

Naveen
