Digital Signature when order TECO

Hello,
I have a requirement now where order TECO need to sign-off. This is requirement by the industry. What i am thinking of is using digital signature to achieve this.
I know digital signature can be configured for operation sign-off as explain [here.|http://help.sap.com/erp2005_ehp_03/helpdata/EN/da/49d9c433ff4985b2484b7b911123cf/frameset.htm] I don't need digital signature at all operation.
What i want is the digital signature when i TECO the order. Is this possible using standard/configuration or do i need to go into development?

Dear Chin,
It si not possible through standard SAP Customization.
As per standard SAP Customization (Activating EHP4 Business node for Electronic signature for PM Order) which is at the combination of PM Order type and Planning Plant - But this will be for PM Order operation confirmation though it will check at the time of doing TECO of PM Order.
It can be achieved using enhancement - by calling the gigital signature screen in PM Order TECO exit.
I already tried the same using the enhancement by creating new screen and checking the signature password while doing PM Order TECO.
I hope this will help you.
Regards,
Rahul

How to deal with digital signatures when converting messages?

Hi there,
this it not (yet) about the actual implementation. It's more of a logical problem that I'm facing.
There are two partners A and B. A is sending an EDIFACT document which is digitally signed to B.
B has a XI instance that is converting all incoming messages into IDocs, in this particular case INVOIC. This IDoc is received by the R/3 system.
All invoices must be archived due to an eventual tax inspection.
In order to fulfill the security requirements all archived data must be digitally signed.
So far so good.
I guess I'm not allowed to sign my invoices with my own private key due to the fact that i could alter the containing data and sign it again.
It's obvious that I cant apply the digital signature from the EDIFACT message to my IDoc because the data has changed and therefore the signature is invalid.
The only solution to this problem, that I can imagine, is to archive EDIFACT alongside IDoc.
Have you experienced a similar problem or do you have any other idea in order to solve this issue?
I hope my problem is well defined.
Any comment is appreciated.
Thanks in advance
Bastian Stratmann

Hi Bastian,
it is not possible to separate the signature from the document signed.
The system A generates and EDIFACT message -> A has the responsibility on this message and so A sign it.
XI manipulate the message received from A, that means XI generates a new message. -> XI has the responsibility on it, so if you want a signature this should be generated by XI.
As the IDoc was generated by XI it cannot be signed by A (neither technically nor logically) because A has no responsibility on it.
XI <b>is</b> altering the message so XI is responsible for it.
In this case you have to store both the EDIFACT message and the IDOC and maybe sign this new document (EDIFACT+IDOC) with XI signature .
Kind Regards,
Sergio

How do I retain digital signatures when merging documents?

We digitallty sign invoices, but when we merge them with the copies of the checks, the digital signatures are removed. Is there any way to retain those signatures in the merging process?

One really crucial thing to "get" right at the start of working with PDFs and digital signatures is this: what is signed is not a page, but a document. This can be painful when trying to convert a paper workflow based on signing pages. But the signature is giving the authenticity of the whole of the PDF. This is, in fact, a key reason why portfolios were invented.

Validating Digital Signatures when they come back to you.

Ok so I've sent out some forms & have received them back
Now it seems that I must "Validate" every signature?
Is that correct?
What does that mean exactly? That I went throught the form & verified all of the information was correct?
Is there anything specific I should be looking for or changing the settings to when I'm trying to validate digital signatures?

First, you need to view the signature to see if it was issued by a trusted source (like Verisign or Microsoft). If a trusted source was used, then it is valid.
More info on digital signatures can be found at: http://office.microsoft.com/en-us/help/HA012308751033.aspx

I created buttons and added a digital signature, when I saved and reopened my buttons disappeared?

I created a multi page PDF with numerous buttons for navigation. I realized I had forgotten to sign one of the individual pages, (I had recently added) so I simply put in a digital signature. I saved the document and reopened it later to find it made all the buttons non functional and uneditable... Some of the buttons were transparent (placed over written dates for reference) and some were colored boxes with text. The colored buttons became "flattened" and I could no longer edit them or click on anything.
Why did this happen? Is the digital signature to blame? Is there a way to edit the existing buttons or do I need to recreate all of them along with the actions associated with each? any assistance would be much appreciated!

It's possible to set up a signature field to lock other fields when it is signed. Could that be what happened? It also possible to choose to lock the file when signed to prevent changes. It's hard to tell what happened without seeing the file.

Target costs not updated timely when order TECO'd

In June 27 I displayed process order xxx in COR3 - Cost analysis report with the status of TECO but the column Total target Cost has no values. In June 29, I again displayed the same but already find an entry in the Total Target Costs. Please advise why there was a delay in populating the target costs.

Hi vijay,
Is it normal that the variance calculation will take 2 days to finish the activity? Will you please specify what activity you mean as well.
Thank you so much.

Firefox when downloaded has invalid digital signature when i try to run programe, the when i run it "curupt file" shows and nothing

It dosent just happen when i try downloading firefox, it happens with every program i try to download and open

Hi,
2 things:
1. Assuming your script is original - it is not asking for a TXT file till it is found in expected location. You can choose between 2 solutions:
to remove FindChangeList.txt from FindChangeSupport folder ==> script will ask for another file
to override this file by your query ==> script will not ask but execute your query
2. You can see greyed TXT files in Script Panel since this panel shows executable files (script's formats)

Digital signature error while confirming maintenance order

hi all,
while i try to confirm maintenance order i m getting following error.
"Unable to find strategy information about strategy
Message no. SIG403
Diagnosis
Signature strategy has been allocated to the function you selected. However, signature strategy has not been defined in the system. The individual signatures may be missing.
The system does not carry out the function."
I checked in SPRO but couldn't find any configuration related to digital signature..
Please suggest how to overcome this issue..
Regards,
Amit kushwaha

Hi Pete,
Digital signature is activated for the function IW41. AS per the SAP help i should maintain configuration in
" Maintenance and Service Processing >® Maintenance and Service Orders> ® Functions and Settings for Order Types --> -->Define Digital Signature for Order Types.
I checked SPRO menu paths to locate above mentioned path. but it is not there
Please suggest !

Multiple Digital Signatures?

Here at my work, we need to use digital signatures in order to protect our sensitive documents. However, sometimes these documents need to go up the chain of command before they are completely "done".
Is there any possible way to have more than one digital signature on a document? When I put my digital signature on something and sends it to my boss and he signs it...it erases the original signature (mine) and his is the only one there.
We need to be able to have both of our digital signatures on the document. Is this possible with this, or any other Adobe software?
FYI: We run on Windows XP, and only a few select people have Adobe Acrobat 7.
Any suggestions, EVEN if it means buying new Adobe software would be appreciated.

It's hard for me to send any files, because most of our documents are snesitive materials, and proprietary information.
We also mainly use things on Microsoft Office 2003 (this document in particular is made via Excel 03), but we are willing to transfer the documents to Adobe in order to get the signatures.
The way we sign things is digitally. However it seems, in no matter WHAT format we use, we cannot make ANY changes to the document without taking the old signature off.
These "documents" usually pertain to job orders, or request forms for new jobs. Several people have to sign off on these forms, and almost all of them need to edit/change/add their own stuff to the forms, as the forms go up the chain of command.
But when the very last person sees it, it needs to be shown as signed by everyone who has seen it. This does not seem possible IF the document is edited in any way.

Digital Signatures for Changing the statuses in Issue Mgmt

Hi
Has anyone put in place digital signatures for Issue
Managemnt when we change the status values in an issue.
We are looking at SAP Note 835584 - Digital signature for documents,
but that is not applicable for us as we want to initiate the digital
signature when the status profile "SLFI0001" kicks in and the status is
changed from one to the other.(eg in process to completed etc)
We have created the digital signature and the strategies, but are
looking for a place to attach this with the status profile "SLFI0001".
Is there a place we can attach the digital signature strategies to this
status profile?
Anyone has any ideas on how it can be done?
Thanks in advance..
sap ques..

We have a document that needs to be signed by more than one individual -- and in our process we are using the Topacz signature pad to get the signature. It's similar to the one you sign at the grocery store, drug store, etc. In order to NOT have the first signature invalidated, we were told to edit the registry...and it works perfectly!
[HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\8.0\AVAlert\cCheckbox]
"iDigSigSaveAsCertified"=dword:00000001
[HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\8.0\AVAlert\cCheckbox\cAnnots]
"iReaderEnableSaveWarn"=dword:00000001
Obviously if you are using a different version of Acrobat, you'll have to change the key accordingly.
Hopefully this will work with your process.
Good luck!!

SAPGUI SNC logon and digital signature

Dear all,
I have setup in a test environment a sap logon with SNC in order to use the active directory authentication instead of SAP R/3 User and Password. It works well. So I can enter directly in the system without specify R3 user and R3 password. My users have no to maintain R/3 password anymore.
Now I have a problem. For some transactions we have implemented the digital signature in order to have a further authentication when we want to perform some critical task. An example is releasing dms document in CV02N transaction.
Our customizing for digital signature is:
System signature with authorization by R/3 user ID/password
The other options are:
User signature with ext. security product with verification
User signature with ext. security product w/o verification
So the system still ask to the users their R/3 password for the authentication when they try to "sign" a document.
Do you think there is a way to configure the system in order to ask and check the active directory user password instead of R/3 password? Where can I found documentation about it ?
My system is SAP R/3 4.70 ext 2 on windows 2003 r2 sp2 x64.
My active directory is based on Windows 2003 x32 sp2 in native mode.

Hi,
We are running SAP ECC Version 6.0 wih Netweaver 7.1. We also talked with SAP about this and they have given a small BADI to disable the R3 user id and Password prompt. However, they informed us to write a own coding to activate/authenticate with LDAP.
Wondering, what need to modify and which functional module. I saw the below from one of the thread...Please let me know what to modify in the coding to make the LDAP authentication works.
+There are some options for what changes need to be made to the SSFT_PPPI_SIGN function module:+
+1. It could be changed to call a SAP supplied function module called LDAP_SIMPLEBIND. This would mean that a user and password entered by user would then be checked with LDAP server (e.g. Active Directory) instead of the user and password entered being checked with SAP user store, which of course won't work when SNC is enabled because user SAP passwords are then deactivated.+

Maintaining digital signatures in single pdf

Is there a way in Acrobat 9 Pro to maintain digital signatures when combining multiple files into a single pdf? For instance, if I sign my timecard and a separate expense report, then my supervisor also countersigns both documents, I lose the signatures when combining the timecard and expense report into a single file. I believe the signatures are maintained when creating a portfolio, but can it also be accomplished in a single pdf?

I tried combining mulitple pdf documents either signed by me and/or a customer into one pdf document and the signatures were lost. However, if you combine them as a 'PDF Portfolio' instead of 'Single PDF' you'll maintain the signatures. The option is located in the right corner of the 'Combine Files' screen.

Digital signatures and combining PDFs in Acrobat X

I hope that one of you Acrobat gurus can help me out with one or more of these questions:
Is it possible to maintain digital signatures when inserting signed PDFs into another PDF?
Is it possible to remove a digital signature after a signature has been deleted from the page?
Is it possible to change the format of the date and time on a digital signature?

In the simplest sense a digital signature is a special checksum of all the bytes in the bytes in the PDF combined with all the bytes in the digital signature. If the document is changed in any way the checksum changes, so the signature becomes invalid. A valid signature ensures that the document hasn't changed since the signature was applied. That stuff that's shown on the signature field is irrelevant. It's just a pretty picture. The real stuff is going on inside the PDF where you can't see it.
Obviously it gets a lot more complext then this. The signature can be selectively applied so that the certain types of changes are allowed. A signature does not add real protection to a PDF, but Acrobat plays along with this scheme by trying to not allow changes that would invalidate the signature, and logging all modifications to the PDF.
1) There are ways to maintain the visual appearance of the signature on the page. If the permissions have been set to allow it the PDF can be flattened, which also partially removes much of the stuff that's going on internally. But this isn't always possible. I had to solve this problem once for a client, so I wrote a plug-in that strips the signature permissions from the PDF (I'll post this to www.pdfscripting.com sometime soon), after which the the PDF can be flattened, keeping the appearance. But of course, after this point the document has to be considered invalid. For example, if the document was a contract, the flattened version would be good for use in an analysis of say all contracts for a particular year, or for copying legal language to another contract, but it couldn't be used as the basis of a legal dispute.
2) I don't understand this one. Do you mean you're deleting the signature field and some of the internal digital signature stuff is still hanging around causing problems? If you own the signature (or the permissions allow), then a standard form reset will "Un-Sign" the PDF. Inserting PDF pages into another PDF will strip out all this info as well.
3) The stamp appearance is set at the time the stamp is applied, it cannot be changed after this point. It's a lot like a PDF stamp.

Digital Signatures in cFolder

Hello Expert,
we do SRM integration with cFolder and want to do the Digital Signatures when uploading document in cFolder .
Do your expert have experiences about it ..or share some document with me.. Many thanks..
Your help would be really appreciated.
Thanks & Best Regards,
Bill

Regarding #1, the short answer is no. Every time the file is digitally signed it necessitates it being saved. That's what allow "View Signed Version" and signature roll back to work.
As for # 2, it depends on the version of Acrobat. Versions 6 and 7 allowed anyone to remove a signature as long as it wasn't a certifying signature. In the case of the certifying signature on the signer could remove. Beginning with version 8 you can only clear if you have access to the digital ID that was used to create the signature.

Digital Signature and workflow functionality in Enh Pack

We are working in ECC 6.0 environment. Recentaly we have activated Enh Pack 3 and 4 in our system. After that I can couple of additional QM functionality in system. SAP has provided few more settings in SPRO to activate digital signature in QN and workflow in standard peace.
I would be wonder if anyone has used those function in standard system without any custom development.
How can we use/ activate those (digital signature for QN and workflow) functionality? Reply appreciated.

SAP IMG > Quality Management> Quality Notifications> Notification processing> Specify Digital Signature
Give details like
Level -Header /Task Notification Type
Business
   Transaction
Signature Type
Strategy
Enter the Business Transaction: like PMM2 for Put notification in process,PMM4 for Complete notification,     QN40 for Release Task etc
Depending on your configuration systems asks for digital signature when you set header level status or Task level status
Means if u set Digital signature for PMM2 for Put notification in process system prompts for Digital siganture.
