Hi Jocelyn,
no quite there yet!
There is a bit of information in the SDN about this subject - please find
a list of some of the stuff I used
https://www.sdn.sap.com/irj/scn/thread?messageID=6160963#6160963

There is a pretty good explanation from Jeff Gebo (a webniar on sending
attachments) - we at the moment are trying to 'tweak' the code a bit so
the Workflow sends the email on a SELFITEM.SENDTASKDESCRIPTION step - i.e.
we want the code to simply return the attachment and then the workflow
will use the attachment in the email step. Jeff's sends the email from
his code.
For one of the Forms we are using (a Transfer Employee form), the
attachment was 29KB - so not too bad at all.
Hope that helps,
Cristiana

Akshay, Whether you can take that approach depends upon the requirements
of your customer. However at this point it is clear this is no longer a
workflow question, but rather an Adobe question - i.e. how do store and
retrieve a pdf WITH it's digital signatures. So you should try raising
the question on the SAP Interactive Forms by Adobe forum on SDN.
Cristiana - My impression was your issue is very similar - so if you have
solved this or have found something useful on the SDN forums you might
want to discuss that with Akshay - preferably via the Adobe SDN forum.

Jocelyn

Hi Jocelyn,
The requirement was a form should be sent for approvals and this form will
have to be signed digitally at every approval.
Now as you have suggested, if I have to retrieve the form filled in by 1st
approver, I have a key number based on which I can retrieve the stored
pdfsource data. Only problem was that I was not able to populate the form
with the digital signature.
So my actual doubt is related to point -4. Displaying the PDF form based
on pdfSource data- because only problem is if I have to display the
previous Digital signature as it is on the form.
Do you mean to say that we can just go on storing the PDF source at every
approval , and during each approval just display the details of previous
approval i.e. when it was signed etc on the form and not the actual
signature?

Hi Akshay,
Well if you are already storing your PDFSource data in a custom table then
surely you would just:
1. Add a key to the custom table
2. Send the key to workflow
3. Have workflow call the ABAP WD program passing the key
4. Using the key look up the table and import the pdfsource in your ABAP
WD program and display it.
5. When the user updates the form with the digital signature, reimport it
and update your custom table.
6. You could use your ABAP WD program to read data from the form to pass
to the workflow container, as well as reading the PDF in full, before
closing.
(After all workflow probably doesn't need all the details of the digital
signature - mostly it needs to know if it was signed at all.)
This would provide data for subsequent steps in workflow, rather than
having to create an attachment or try and get the workflow to parse the
file in background.
Similarly if you were sending the form offline via email or uploading a
returned from via email you would need the key as well as the PDF.
The approach would be much the same regardless of what storage area you
use.
The point is to get away from thinking of workflow as the carrier of the
document. Rather workflow handles the communication needed to complete the
process. It's the ABAP WD program that accesses the PDF document. So all
you need is for the workflow and the ABAP WD to agree on some way of
uniquely identifing a document.
Please look at the Adobe tutorials on SDN.

Jocelyn

Hi Jocelyn,
Thanks for the inputs.
But I am not able to visualize how can I use the retrieved data?
e.g. In my case As this is custom application, we had created a custom
table and stored the data from PDFsource of context in custom table as
Xstring. However, problem is how to use this data for displaying again as
PDF?
Another issue is how to reproduce the digital signatures from this data?
Even though it's stored inside XSTRING ,,,
So I thought of using the form getting manually saved on Front end when
use digitally signs it.
Then create attachment of it - then use it for further purpose inside
workflow.
Now the issue was how to create attachment in background step of workflow.
Please suggest.

Hi Akshay,
Ok well if that is the scenario you might want to approach the problem in
a different way. Rather than pass attachments around, which is always a
pain when you have to convert between different formats, why not just pass
a reference number ? i.e. assign some sort of id to the form. Your
actual binary data representing the current known form would be stored
somewhere in SAP. Some applications such as SAP HCM Workforce Process
Management have used Records Management (transaction SCASE) to store the
binary/XML data of the form and then assign a GUID as the reference that
is passed throughout the workflow. Then your ABAP WD application uses the
reference to read/update the pdf. It's not particularly important where
you store it from workflow's point of view - so long as you can use your
form id to find the form data.
Trying to use SOFM - which is really only intended for creating and
displaying attachments - will be very restrictive. Also passing around a
large attachment in the workflow is likely to have other implications -
e.g. sizing issues.
You might also want to look at the many Adobe tutorials on SDN. There are
various approaches to handling incoming PDF forms.
Regards,
Jocelyn

Subject: [LIKELY JUNK]Workflow and PDF attachments
Hi All,
I know this topic is discussed a lot, still posting the questions as I am
not able to achieve the requirement.
Just to elaborate the scenario, we are using Web dypnro for ABAP to host
Interactive form .
This Form in turn triggers the workflow, as this form is to be approved
using workflow process. i.e. UWL will be used to launch the form when
executing the work items.
As the form includes Digital signatures, we are not able to read the same
from contexts (e.g. using UWLs dynamic parameters such as WI_ID.) So we
have decided to use attachments i.e. send this form as an attachment
inside workflow, since saved PDF file has all the data intact.
Now the issue is:
How this form in Webdynpro is to be saved as PDF file automatically and
then send as an attachment in workflow?
1. I have tried using SAP Office function modules such as SO_OBJECT_UPLOAD
to create PDF files in SOFM object. However the problem is these FM s can
not be used from Webdynpro as Front end services are unavailable.
2. Same is the issue If I use background step for creating SOFM document
so that it can be used as an attachment.
Can any body please suggest what approach can be taken so that from
webdynpro , attachment can be created and passed to workflow seamlessly?
Any inputs are appreciated.
Thanks in advance.
Regards
Akshay Bhagwat
