Equipment or Sub-Equipment

Dear All,
I have an requirement, my client has CNC machines and press machines for production. The machines have coolant tanks for CNC's and measuring devices in case of press machines.
How do i represent these machines in my system, as a equipment, Assembly, sub-equipment or utility.
Your valuable inputs are awaited.
Points Assured, Thnkx.

Rashmi

Hello Rashmi,
this is a very good question and we all go through it when we first start with SAP PM. I believe that there might be different answers and different solutions to one given situation.
It is good to understand the basic use of the different SAP objects (although you could almost make any use of them, there are still some guidelines).
Functional locations should be used for objects which remain more static, like a building ... It also provides you with an hierarchical structure in its name, what is usefull to represent a geographical or logical organisation, or such upper levels. It provides you with a nice structure list through use of IH01 transaction. To that structure, you can attach materials boms and/or equipments.
Equipment and sub-equipment should be used for objects which can be installed and dismantled into/from functional locations, like a table in a buidling ... It provides you with the usage list which is able to track the changes you make on the equipment. Unlike the functional location, you do not visualize the structure in its name, but you can attach as many sub-equipments as you want below.
The subject is too vast to capture it all in a few sentences.
In your example, i would represent the CNC machines and press as functional locations (if you do not move them often) and related equipments as equipments and sub-equipments which you can install and dismantle into/from machines if this is part of your business process to do so. If not, then everything could simply be functional locations.
I hope this will help you.
Eric.

Table Link between Equipment and Sub-equipment

Hi all
My requirement is this
I have one mobile set with a serial number. for that mobile set i have one battery with a serial number, now i want to link both the serial numbers, one as main and another as sub item
I tried by maintaining the battery serial number as sub-equipment in the main mobile set equipment number master,
Let me know the table link between equipment and sub-equipment
I want a report based on the input mobile set equipment number what are all the sub-equipment associated with the main equipment
Also suggest is there any other approach,
Regards
Amuthan M

Hi
EQUZ is the table,if u give the sub equipment in equipment field and execute.you can find the main equipment in superior equipment field

Sale of Equipment with sub-equipment attached

Hi fellow members,
We have a business scenario where two different serialized materials are assembled into a single composite unit and sold to the customer. The single unit sold to the customer also has a serial number on it. We are required to track the serial numbers of the individual components as well when the main unit is sold.
There is a sub-equipment option that could be used to attach the individual serialized devices to the main equipment. However, seek the following inputs from you:
a. Is there a way where the equipments can be attached to the main equipment master record automatically when the composite unit has been produced ?
b. If we sell the main unit, the system status of the equipment record gets recorded as ECUS. Will this also change the system status of the sub-equipments to ECUS ?
c. What is the approach to be used if we would like to create one composite unit from two individual materials without the use of a production / sub-contracting order ? Can this be done via a direct movement type ?
Appreciate your help
Regards
Rohit Zalani

Hi
The scenario you described is a production process & if you map it through PP order processing it can be tracked through its cycle. However you have following alternative as workaround-
1. Create the finished material as equipment with serialised material & with construction type feature.
2. Create a material BOM of the main material & you will get a structure of two material.
3. Component material can be serialised for their own identity.
4. You maintain the equipment master if required for the main equipments, no need to creatre equipment view of the component material.
5. Further your question- If we sell the main unit, the system status of the equipment record gets recorded as ECUS. Will this also change the system status of the sub-equipments to ECUS ?
Ans- No equipment status are maintained individually

Difference between Sub-Equipment & Equipment BOM

Can Anybody Please tel me the difference between Sub-Equipment & Equipment BOM ?
Since both are Sub-part of the Equipment , on what basis these two items are differentiated ?

Sub-equipment:
Suppose there is a overhead cranes in a coal yard, and your client mapped coal yard as functional location and cranes as eq-1 in SAP.
but a overhaed crane has many equipment like -
1. LT motor (long travel)
2. CT motor (cross travel )
3. gear boxes
so u can categorise all above equipment as sub-equipment in SAP and each sub-equipment having one superior equipment as eq-1 (crane no. 1)
Eq BOM:
Equipment BOMs are used to describe the structure of equipment and to assign spare parts to equipment for maintenance purposes.
simply, what are the components and quantity being used to make this equipment.
electric motor having component like
1. bearing
2. nut-bolt
3. casing
4. armature
5. winding
6. carbon brush
like may be more than 50 components.

Breakdown of sub equipment

Hi Gurus,
I have an equipment that has sub equipments. If I create an maintenance order for the sub equipment, I want the breakdown of the sub equipment to reflect in the main equipment. Can I do that?
Thanks,
Paul

Hello,
Normally, the sub equipment will be dismantled from the main equipment and do the work and re-install the same. The dismantle date time and re-install time and details will be updated in the Equipment Log.

Should I use Sub-Equipment Hierarchy for sub-systems (first post)?

I am 2 months into the maintenance manager role for a fleet of Locomotives and it has been decided to use SAP PM by senior management based on a separate business arm requirements.
I believe for this to be successful the first step is to get the structure right so that data is collected in the most logical manner.
I intend to use SAP to schedule all maintenance tasks based on measuring points and dates of previous work orders, capture system and sub-system failure history, capture costs and parts usage and trend performance of subsystems based on their own and system level measuring points.
I have been told that all locomotives are assigned to a single functional location within the business model. The individual locomotives themselves are assigned as separate pieces of equipment in this functional location.
Within the individual locomotives there are a series of subsystems that have associated maintenance requirements based on time and usage and they are serial number tracked. These items are exchanged between the locomotives and the warehouse upon failure, upgrade or overhaul and include:
AC traction Motors
Wheelsets
Diesel Engine
Main Generator
Auxiliary Generator
Dynostarter
Gearbox
Compressors
Traction motor blowers (Fans)
Radiator fans and AC radiator fan motors
Is it logical to put these as sub-equipment within an Equipment Hierarchy with the Locomotive being the superior equipment?
Should notifications regarding their failure be assigned to the Superior Equipment (Locomotive) or the Sub-Equipment and what are the implications of each? If assigned to sub-systems can I still report on system reliability by "rolling up" the failures?
Do the measuring points (e.g. kilometres) assigned to the Superior Equipment (Locomotive) accumulate to the Sub-Equipment automatically and does installation and removal from different Locomotives with different kilometres affect this? For example a traction motor in Locomotive 001 is installed from 100,000 to 360,000 locomotive kilometres and then it is installed in Locomotive 002 from 300,000 to the current 340,000 locomotive kilometres. Does SAP accumulate 300,000 kilometres of life to the traction motor sub system based on its superior equipment's measuring points?
I have many more questions to come that I will most likely solve through experimentation and future questions, but in order to hit the ground running I would appreciate your feedback if any of you have similar experiences.
Thanks in advance
Glenn Sanders

In SAP, you can define "N" no. of hierarchies for Functional Location & Equipment.
But in the reporting, you can get the costs at Functional Location level & Equipment level at next. Its not possible to have Sub Functional Location level or Sub Equipment Level.
Also, you have mentioned that you will interchange the Sub components between Locomotives. Also, you want to maintain those using Serial Numbers. You can define these Sub Components as Assemblies with Serial Numbers so that Equipment can be created for those combinations.
To maintain Measuring Point for Sub Components, Equipment should be created. In SAP, you have the option to transfer the Measuring Points from One Equipment (Superior Equipment) to another Equipment (Sub Equipment).
While interchanging the Sub Component from One Locomotive to another Locomotive, without Measurement Reading Transfer, you can dismantle & install the same.

Update superior equipment status based on sub equipment status

Dear friends,
I have a scenario for calibration process for which there are two equipments .One sub equipment and the other superior equipment. Calibration process is done for sub equipment and I have given usage decision as rejected based on which sub equipment staus gets updated as NPRT(PRT not ready for use). Now the client requirement is as that the superior equipment also get the status NPRT since they are linked through superior/sub equipment relation. Kindly suggest some solutions.

Arun

Dear friends ,
I have observed that if a sub equipment is assigned to a superior equipment ,the equipment status of sub equipment does not get updated when calibration process is run.(NPRT status does not get updated if an equipment is installed to a superior eqpt when usage decision is made for not accepted). So there is no possiblity of updating the superior equipment status. Hence kindly ignore my query.

Roll up sub equipment cost to Superior Equipment

Hello,
Is there a way to see sub equipment cost to the superior equipment.
We have a pump (superior) then under that we have motor (sub) and elec (sub). Is there a way to see the total cost of the two subs in the superior.
Thanks.

Another work-around is to get your list of equipment, say from IE05.
Then paste the equipment into IW39 to get your costs

Temperature indicator & pressure gauges as sub equipment.

Dear All,
I have four Flavour Tank in my plant which is created as Equipment.
Each Flavour tank is having 3 Temperature Indiactor & 2 Pressure Gauges installed on it.
Can we create these Temperature Indicator & Pressure Gauge as Sub Equipment & installed at Flavour Tank which is a Superior Equipment.
If yes, then can we perform all types of maintenance on these sub equipment. Here mainly i have to execute calibration orders & b/d maintenance for Temp. Indicator & Pressure Gauge.
What are the advantages & disadvantages of sub equipment functionality. This i need from process & reporting point of view.
Thanks & Regards,
Sandeep

Hello Sandeep,
Sub equipment is not a special type of equipment in SAP. It is normally a refrence object as a normal equipment. You can perform each and every function over it as u perform on normal Equipment. It has some advantages like inheritence of warranty, Structural display etc. As per cocern of disadvantage i dont think that there is dis advantage. So you can procedd further.

Relating sub equipment and the operation

Hi All,
How can i relate the sub equipment with operation of a PM order ? I am getting the the order details through "BAPI_ALM_ORDER_GET_DETAIL" but nor able to make out which operation/activity corresponds to which sub-equipment.
Please help.
Thanks,
Nagraj

It appears that you cannot determine which equipment belongs to which operation via the data in this BAPI
You would need to do some post-processing.

Equipment ---- Sub-Equipment heirarchy Requirements

Dear All,
While assiging super Equipment to Equipment do we need to confirm anything in master data , ie .Do we have any mandatory master data that have to be same??? or anything
plz guide

hi
there is no mandatory field for this ,if you have created with max amount of data in superior equipment then some fields will be automatically copied to your sub equipment while creating

Asset data should flow to sub-equipment

Dear experts,
My requirement is whenever i'll change Asset No.in parent Equipment it should flow to all sub-equipments.
I mean it should be changed in all sub equipments too.
Is there any standard detting is available regarding this?????
Thanks
Rahul
Edited by: RManchanda on Jan 3, 2011 4:56 AM

HI RManchanda ,
Where you are storing Asset Number ?
If it is in one of the std field of SAP, then I don't think it is possible to reflect any changes in Parent equipment will reflect in Sub equipment.
For this you can go for some sort of development or LSMW for to change sub equipment.
Hope this will help you.

DETAILS OF SUB-EQUIPMENT

Dear PM Consultants,
The issue is , In each Equipment 4 to 5 sub-equipments are installed and people are creating Orders and Notification on Equipment and also on Sub-Equipments.
If I run IW39 based on equipment and for a particular period, it will give the details of order created created for the selected equipment only and not the details of order or Notification created on sub-equipments installed in the equipment given in the selection screen.
Eg Equipment-E00001
     Sub-Equi -S00001
                    -S00002
                    -S00003
For one month (say October) orders created on E00001-5
                                                                     S00001-2
                                                                     S00002-3
                                                                     S00003-6
If I run IW39 for E00001,Is there is any possibility to get details of orders created
on S00001,S00002&S00003,Bcoz it's all areas of main equipment E00001.
If not, is there is any std report,where I can get this info.
Thanks and Regards
ISWARI

hi iswari
Sub equipment is used for structuring your system for exploding the equipments futher .it is just to diplay the hierarchy of the equiment.if you create an order for superior equipment meant that it is only for that equipment only.it will not be consisdered for sub equipments, because you are maintaining seprate master record for equipments as well as sub equipments.i dont think there is any seperate report for sub equipments , in IW39 itself you can specify the equipments for which you want to see the order generated.
i hope you will be clear on this
