Change Number of a BOM

Dear Gurus
While changing a BOM i want to give a change number. Do i hve to create a change master for that change number or i can directly give the change number as a input on CS02?
If yes then how do i create a change master?
Pls Help
REGARDS

is ECM is in Scope of your client?
If yes, you can create a Engineering change request in CC01,
In the object type select BOm Tick actv,object
and enter the material No and plant
while saving system will give change No
this No you need to enter while changing BOM

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.

Edit or Change a Change Number in BOM

Good Day
Dear All
Please can anyone can tell me is any process is there to Edit or change the CHANGE NO in BOM

Hi Radhakrishna,
Masters like BOM and Routing can be created and changed with change number. Accordingly changes can be tracked with respect to the change numbers. For Eg BOM created wit hqty 10 with change number X , then BOM changed to 12 with change number Y, then system will display the reports on BOM changes with respect to change numbers. Historial data you can track.
You can create new change number in CC01 with different validity date and make changes to BOM. You cannot edit the change number once its is created.
Have a look on the below doc posted by me on usage of revision level with change numbers.
Usage of Revision Level for PP Masters -BOM and Routing
Thanks & Regards,

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.

Praveen

BOM Change Number

How to make change no mandatory for BOM creation and change?
The required config should not impact any other objects except BOM Creation & Change.

Dear Venkat,
In case of CS01/CS02 to make the change number as mandatory,follow this steps,
1.In OS27 - Check box included for BOM validity maintained,EC Management active,History Requirement.
2.In OS25 - BOM usage 1 & BOM status 1 - History Requirement check box is included.
3.Authorization object C_STUE_NOH is with No.For this you should take the help from your BASIS
consultant,while creating a new role in PFCG for this Authorization object C_STUE_NOH the value must
be set as No.
In most of the cases consultants peform the first 2 step alone,in that case only a warning message is displayed,only if step 3 is
done ,an error message gets displayed and the user cannot enter or make any changes for the BOM without any change
number.

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.

Mangal

Different Effective Date in One BOM with only ONE Change Number

Hi gurus
here is my complete question?
Is it possible to realize this function that Different Effective Date in One BOM for different BOM items with only ONE Change Number?
Thanks for your information/help in advance.

Dear Zhao,
Using One change number it's not possible to define a different valid from date for the BOM changes of a single material BOM.
In case if the same change number is used for making different material's BOM component,then a different valid from date for
each BOM can be defined,but at any given point not for each component/item level of the same BOM.
Check and revert back.

Error when I change the BOM without a change number

Hi,
I would like to receive an Error when I change the BOM without a change number.
I define the modification parameter (EC management active and History reqmnt), I configure history reqmnt for BOM (I choice the status 1 and 3 for my BOM usage 5)
In change the message type I dont have the really message number in the liste.
How can I create a new message (045) so that I get an error by changing the BOM without a change number.
Thanks

Dear Dede,
check for the Authorization Object C_STUE_NOH for the
particular User Id's for which you want to Create or Change a
BOM without a Change number.
So assign this Authorization Object under all user id's for which
you want to have this control.
Adding the mentioned Authorization Object in particular User
Id's will resolve the problem.
This can be done using PFCG T code by adding in particular
Roles.
Revert back incase of any clarifications.

Change number in bom

I want to make change number in CS02 and CS20 as mandatory. Pls suggest the procedure..

1.Change number is used to create / change BOM with respect to a change number. The reason for using this field is, in many organizations, they use the concept of ECM, where-in each change needs to be monitored & logged. So a change number is first created in CC01 & then the same is assigned in cs01.
2.This change number must be allowed to use for the business object BOM,which means whilke
creating the change number you have to include the settings for usage in BOM.
3.Using the change number we can trace the history of the BOM.
4.History includes the created date,changes made,it might be an additon of componet or a change in
the component details,a deletion of compoent.
5.There are certain config settings to make this field as mandatory,otherwise the system will allow you
to create or change a BOM without change number in CS01 or cs02...

Change number that are not created earlier accepted for change of BOM

Hi,
When i am going to change BOM it gives warning message "Enter change number, BOM has history requirement"
But my problem is when i put any number in field of change number it is allowing me to change the BOM.
It should not be accept any number that are not created earlier in the system. It must have to accept change number that is created for the history requirement for perticular material. kindly give your input on this issue.

Hi Atul,
Please refer the thread ECM-Problem with Change number in CS01 and CS02 Transactions

Cancel ECN in BOM & remove change number in Routing

Dear Gurus,
I have 2 questions about ECN , pls. help .
1> If we made a wrong ECN in BOM with change number, pls. advise how to cancel this ECN in BOM.I tried to delete the change record in CC02 but it's not allowed since BOM has been changed already.If I made a new change in BOM with new change number, in BOM it will show a new change number, but I don't want to show these change numbers because it should be no changes happen, pls. advise how to recall the change and remove the change number in BOM .
2> We use change number when we change routing ( CA02) in the past, now due to some internal issue, we want to remove all change numbers in routing, I can't find any option in CC02 or CA02, pls. advise is it possible to remove existing change number?
Thanks & best regards,
Tina

Dear Tina,
In my understanding you may not be able to delete the change number assignment made in BOM or routing.
But you can define an alternative date for the made changes and set the valid from date as say 31.12.5555.
Check and revert.

Error in change number creating BOM in Engineering Type.

Can anyone guys help me with my problem.
I'm creating Bom using BAPI_MATERIAL_BOM_GROUP_CREATE.
Every time I create BOM Using one bom only in engineering and all BOM for materials were created.
But every time i create rerun the program and have different change number on its components, the error occur,
"Generation not Supported for Change number"
Can anyone help me with this?
Thanks and God Bless.

In case errors rollback.... I beleive the following logic would resolve your issue.
constants:c_error_type(1) type c value 'E'.
call function 'BAPI_MATERIAL_BOM_GROUP_CREATE'
    exporting
      testrun                  = l_testmode
    tables
      bomgroup                 = l_bomgroup
      variants                 = l_variants
      items                    = l_items
      subitems                 = l_subitems
      materialrelations        = l_materialrelations
      itemassignments          = l_itemassignments
      subitemassignments       = l_subitemassignments
      return                   = l_return.
if l_testmode is initial.
    read table l_return with key type = c_error_type.
    if sy-subrc = 0.
      call function 'BAPI_TRANSACTION_ROLLBACK'.
    else.
      call function 'BAPI_TRANSACTION_COMMIT'.
     endif.
Thanks
