Change Number
     Number used to uniquely identify a change master record.
Engineering Change Management (LO-ECH)
Data record that contains all the information required
for managing a change.
A change master record contains descriptive data, such
as the reason for the change, and data with control
functions, such as valid-from date and indicators for
object types. In addition to this data, which you can
maintain directly, there is data that the system updates
automatically, such as administrative data.
Use
     If you make a change with reference to a change number, or create an
     object with a change number, the following functions are at your
     disposal:
     o   The system determines the validity conditions
     The conditions that the change is effective under can be defined in the
     change master record as follows:
         -   Changes with a date validity (valid-from date)
         -   Changes with parameter effectivity (for example: serial no.
             effectivity)
     o   Log of the changes made
o   Documentation of the changes
o   Assignment of a revision level to a change state of a material or
    document
o   Release of changes for the different areas in the company

Daily Change Number.

Is anybody using this functionality in your SAP system ? This is different than regular change number.

Dear Vinay,
I will explain very clearly,
1.If there are changes in material master which will become effective immediately,then ECN without release key will be created and the
changes will be made with respect to that Change number.
2.If the Changes are for a BOM ,then ECN will be created with Release key and the changes will be made.
3.Once if the changes are to be made effective,then in CC02,by entering the Change number the same will be released and the
changes made with respect to that ECN will become effective.
4.IF the BOM changes are to be made effective immediately,then ECN without release key itself can be used and the changes can be
made or create with release key ,but after making BOM Changes,the same has to be released.
5.Daily an ECN will not created,if needed then it will be created on that particular day.
6.Revert back if more clarifications are needed.

BOM change number field is compulsory

Hi Guys,
I need to setup BOM (CS02) change number entry field is compulsory (using TCode CS02). How to setup config settings? pls advise
Thanks,
Sankaran

Dear Muthusamy,
Even if you have maintained settings in OS27,In T code CS02 ,the system allows
you to change the BOM without a change number.
The same question was posted by Mr.Anbalagan ,3 days before.
The follwing are the answers which I posted to him,check this under post thread name ECR Number
If you want to make Change number field as mandatory for CS02,u have to do it
using the authorisation object.For certain users you can make this as an
mandatory field ,just discuss with Basis & ABAP consultants,they can help out
you in this regard.
Though you might have done settings perfectly in OS27,OS54,but the system
allows you to change a BOM without any change number.
Answer2:

Plz make this Authorization Object C_STUE_NOH as mandatory for T code CS02.
I'm sure BASIS & ABAP consultant can help you in this regard.
I have checked in my system for certain users,like without change number it doesnt allow to change BOM,
So after giving SU53,I found the authorization obeject C_STUE_NOH was missing.
So go ahead in using this object.
answer3:
You can make that field in CS02 as a mandatory for certain users,using a field
exit.
Field name AENNR -Change number can be made as mandatory .
Plz explain the case to ABAP consultant.
First in SE37 he will be checking whether this particular field AENNR has got a field exit.
Later on he will be writing some codes to make this field as mandatory.
This is what i wanted to convey to u.
In my project ,for the core users the field has been made mandatory,so in CS02,he/she cant go inside without giving the change number.
At that time when u give SU53,this authorisation object will be found not given.
So just have a word with the ABAP consultant,he can help u.
Reward points if useful.

Cancel Change Number control in material master routing maintance?

Dear expert
In our company, we have PLM function and must enter change number in material master and routing screen
MM01/MM02 CA01/CA02,could I cancel this control and where is the configuration path in SPRO?
Thanks
Linfeng

Kindly check in OS54.
Under Revision Level, unselect the check box Rev. Level active. If you want that automatic, you can go for Rev. Lev. Automatic. Before doing any changes in config, please explore pros & cons of the same.
For routing, in OP5A, set the field selection as Change Number - Input

System Change Number

hi
i know that each transaction that is committed is given a system change nunber...i saw in the
Oracle 9i upgradation book and it was talking about the Check point system change number....i
know about SCN but this thing has created some ambiguities in my mind...so is there anyone
who could explain that what is Check point SCN....and another thing that is introduced in
Oracle 9i is Row level SCN and previously SCN was Block level but still default is Block
level and wqe can tell at Table creation that what should be used...whether Block level or
Row level....
kindly explain if someone could and also tell the whole functionally of SCN in database
Regards

Salman, as far as I know the checkpoint SCN is just the SCN number at the time of checkpoint.
Also Oracle has had both block level and row level SCN numbers for some time. When a block is accessed and updated via indexes the row level SCN is generated while a full table scan just uses a block level SCN. This is a performance gain for the full scan that does not have to perform a row by row check.
If you were to refer to the specific manual, topic, and section you are having a problem understanding I or another poster may be able to discuss the material with you.

Change No in MM01

Dear All,
In MM01 transaction, change no field what is significance & use of this.
is any config of this please guide.
Thanks
Shital

Dear,
In material master you can make your changes with reference to a change number. This identifies a change master record in engineering change management and has the advantage that changes to different objects (such as the material, bill of material, or routing) can be grouped together under this number. If, for example, a particular product gives rise to a complaint, you can record any resulting changes to the relevant objects under this number.
If you process a material with the function Change ---Schedule, then you can change the material with reference to a change number if the valid-from date is in the future.
Configuration link has already given you by Mr. Vikas refer it.
Also refer this link,

The number range also share by Purchase document , in ME23n, in the change document, i can see the change number display. It share the same number range as work center.
Regards,

hi both,
I still do not find the setting for change document.
Let me explain what had i explore so far
In tcode : CR10, i click on the change number document display. then i see the structure holding this value "field is CHANGENR". Then i use the "where-used" function and see what other "table/structure" that also using this field CHANGENR.
In SE11 , table CDHDR, i input change document range, and the object of the
client, object, object value, document number, name, date, time,tCode, change number,.......
018 RESSOURCE 10000245 0000403630 FEMS_DEV 12/04/2007 10:59:02 CRAV U E

Mat master-change number

HI
in mm01/mm02 initial screen Chnage number is there .
i tried to eneter some no say 99 in change no field & mat code system says change no deosen't exist.
wat is the use of Change number,
where we need to do setting in order to use it

hi
1) change material no is come in to picture when there is change in PRODUCT , and that change is finalised & released thru ECN ( engg changed note ) .
If the master for same product is avaliable and one has to go for Incorporate changes automatically in VALIDITY, PRODUCT CODES , EANs and so on by using this featre.
in short is reference no from which one can easily trace out the how many times mat. is changed ?
2) is a one can easily control change type thru SPRO ,
path is LOGISTIC GENRAL > Engineering change management > DEFINE statuses for change master records.
records are continaing change type ..
hence u have to define change statuses and change type also u have to define number ranges for change number.

Avoiding old change number utilisation in BOM

Dear All
My Client Situation is like explained below
We have a Team called "ME" This team is responsible to create /modify the BOM whenever a modification is to be required
Change number is mandatory,but the user is giving the past change number and modifying the BOM.This is to be rectified
i.e., user should not use the old change number

Hello Vignesh
your result is "curious". The use of "change numbers" is not easy (not to say very tricky) in EH&S. Could you please provide more details regaridng how you have prepared the set up of the change number and how you have applied the process?
Normally this is the process: you generate a change number so that data should be valid starting on some day (lets assum 01.01.2011). Now you should be able to do an upload by using the change number you have defined. Now If you take a look "today" in the system you should not "see" the loaded data.But you can change the "key date" in CG02. If you do so and you would select 01.01.2011 you should find the loaded values as an "add on". Now depending on your set up a number of results could come up.
E.G. one possibility to use change number is to prepare DG data whcih should be valid in the future. To do so the "old" data must be "deleted" in some sense so that you have "unique" DG data starting this day.
One further posibility is to perform an "update" on an existing datan record using change numbers.
So it might happen that you have now "deleted" your "old" data by "wrong" using the change number approach.
To my knowledge there is no way back. The EH&S system has performed a "split" in the data records in such a way that the old data does have noe the "Del" falg and is valid until "yesterday" and the new data record are valid from now on not having the del flag.
So I am sorry. There is in my opinion o easy way to get the old data "back".
May be refer to:http://help.sap.com/erp2005_ehp_05/helpdata/en/c1/eda0f591ec12408b25e7a1b369ca45/frameset.htm
Chapter " Engineering Change Management for Specifications". You will find there some explanations and a very seimple example etc.

How to find Change number for a Material

Hi,
If we know the material number and Revision level then how can we find the Change Number of that material.
Is there any table in which i can find Change number for a revision level or is there any Function module available.

Vaibhav

Error while changing BOM with change number

Hi ALL, Please help me with followed error message, I am using ECM. I created ECR and converted to ECO and then released.
Object management record cannot be generated
Message no. 29046
Diagnosis
You want to change the BOM with the entered change number.
One of the following situations triggered this error message:
1. The indicator that allows automatic generation is not set for object type BOM in the change master.
2. The indicator generation only on initial creation is set for object type BOM
3. You are processing a change request.
System response
The system checks whether the indicator object management record will be generated is set in the change master.
If the indicator generation only on initial creation is set, the system checks whether the BOM exists in the system.
Procedure
If you are authorized to change the change master, execute the following steps:
For 1.)
Set this indicator for object type BOM or create the control record in the change master.
For 2.)
If the BOM already exists in the system and the generation only on initial creation indicator is set, the system can no longer generate the control record automatically.
In this case you have to add the object control record to the change master first, then you can change the BOM in relation to the change number.
For 3.)
You cannot generate any object control records for a change request.

Hi
With your question regarding changing BOM with change number it looks lke there may be problem in defining the Object types,objects.Moreover whenever converted to ECO you need to enter into cs02 tcode for changing the bom with relevant change number and valid from date.
Hope this gives you a clear idea.let me know if you need anyfurther inputs.
Regards
Praveen
