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".

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

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,

Change Number Issue in CG02

Hi All,
I created a change number and uploaded certain identifiers for some substances. After uploading i am amazed to see that the previous data(Identifiers) available are overwritten and also all the property tree values are deleted. Now could you please tell me how can i retrieve the old change number data again, or is there any possibilities to delete the existing change number. Note : I tried to delete but i got a message that "Change Numbers not deleted(Materials Exists). Please help me on this issue.

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.

Lync User Phone Number Changed in AD - Still Showing Old (Normalized) Number Days Later in Lync Client Contact Detail

Environment: Lync 2013 backend; Lync 2010 and Lync 2013 clients. Enterprise Voice not implemented. November 2013 CU Applied on Server.
Issue: Lync user (User A) phone number changed in AD but still showing old number for others days later.
Believed Cause: User A has not logged into Lync since change to republish new phone number?
So after reading this http://masteringlync.com/ I am beginning to think that something I perceived as an issue may actually be by design?
Action:
User A work phone number changed in AD. User A has only one phone entry in AD. Normalization rule in place to basically leave number unchanged (working)
Result:
New phone number propogated fine to Exchange/Outlook fine. Old number displaying only in Lync client when viewing User A contact card detail
Lync 2010 Client displays only old number when looking at Client A contact detail (this client only presents phone numbers if they are actually normalized)
Lync 2013 Client displays two work numbers.
One that we identify as a "display number" just as entered in AD - this shows correctly as the new number. Another that we identify as the "normalized number" which is still the old
number (same as 2010 Client)
Same results whether contact is saved in Lync Client or not and is not related to Outlook contacts - in fact one test was with a Lync account that is not Mail Enabled.
I did a dbanalyze to view the SQL database detail for User A and see that Category 'userInformation' has the old phone number and the time stamp on it seems to coincide with a Lync Cllient database change (user login or refresh on that end) so this seems
to futher confirm my findings thus my reaching the point of conceding it might be out of my control.
My Question I guess is ....
Have others discovered this? Is this a bug or do normalized phone numbers actually requre a client login to accept/republish the number correctly to others even though the information is updated in AD? User detail and how it propogates seems to
be the biggest mystery and it gets harder and harder to explain to users why changes aren't displaying accuralely.

Thanks Richard... your blog definitely hit home with what I was seeing but guess I just didn't want to accept that as the end of the road on this. I'm still in a little misbelief that client interaction is necessary to update a backend change.
This process really makes phone numbers in Lync an unreliable source given a user will never know if it is it up to date. And the problem with Lync 2013 client is it shows both numbers in the client ... the address book one with the
updated AD numbers and the one the normalized AD one that the user has to login to republish. I now more fully understand the process but trying to explain that to users when they see different work numbers .. ugh.
Oh well, guess the important part is to understand the process so thanks again.

I swapped my iphone from apple store india and my imei of iphone changed and i have lost the box and bill of phone , how can i get my old imei number.

I swapped my iphone from apple store india and my imei of iphone changed and i have lost the box and bill of phone , how can i get my old imei number.

Of course it changed. A phone's IMEI number is unique to each phone. The IMEI number for a phone does not transfer to another phone.
Since your iPhone was exchanged under warranty without having the box and bill for the original purchase, you don't need it now either. The exchange under warranty remains under the warranty for the original purchase.

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.
Regards
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.

Changed number and facetime is still using old number

I added a 3rd line/iphone to my AT&T account. When i bought the iphone at the apple store I asked for a 626 area code but was told the only option I had was a 312 area code. I then called AT&T to try to change the number to a 626 number but was told I couldn't add a line from a different market to my account. So I transferred the line to a second account by itself in order to get a 626 area code for my nephew. Now that iphone will not allow me to facetime it using the 626 area code which is the iphone's number now. I have to facetime the old 312 number in order to connect to it, but that number was canceled minutes after i purchased the iphone. And when my nephew facetimes me, my iphone displays the old 312 number. When I try to facetime him I get a "facetime failed" error message. iphone has been restored and has 4.1. Phone number under phone settings has been changed to the correct 626 one. Can't think of anything else. Anyone experiencing the same problem? Thanks
~R

I downloaded the facetime app. I have it going through my email address. Now my wife has Iphone 4. When we first bought her phone, ATT gave her a dumby number for the reason of switching from another carrier. After her contract was up, we ported her number to the iphone. Dumping the other number for her orignal.
So when I tried facetime by calling her phone it would not connect. I was puzzled. I tried it a few more times and still nothing. I decided to take her phone and call me and it worked. I was confused when another number showed up. After pondering this for some time, I then noticed the number was the dumby number ATT gave her. This number was dumped 2 1/2 months ago.
Now I know facetime for Mac is just a beta version, but does anyone have an idea * is going on here?

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...
