This question had been asked on two different forums and answered on the first thread the day after the question came up.  That complete answer can be found at http://forums.adobe.com/message/3903889#3903889

The heart of the problem was that large images were being placed in XFA image fields. Due to the design of PDF and incremental updates, copies of these images were being added to the file for each file save.  I'll write more on this later, most likely on the ADEP product blog.  But for now, the solu...

You sent a file to support that shows the problem well.  The signed file had 7 incremental updates, and each update was about 1.3MB. But I noted that the image size varied significantly. Some were GIFs were 3KB while the TIFs were 360KB (all measured on the base64 data).  I would venture to say that...

I'd like to see one of the files that has grown so much.  Or, better yet, I'd like to see a sequence of files, base, after submit with one image, after the next submit that adds another image, etc., and we can diagnose from there; also, a step where just some of the form data, not pictures, are chan...

I've been in touch with the support person in Edinburgh and looked at your files and your various attempts to make the size smaller.  Simply stated, it really is working as designed, but it is difficult to appreciate that unless you go a bit deeper into the file.  Or, to say this another way, it gro...

Did you catch my comment on your recorded video. assuming that you're the same person?  The issue that I saw there is that you were including images in the form data, and that they image was a 1.9MB TIFF file. Each image that you include will become part of the saved PDF. You should use an appropria...

Niall is correct for a direct-connected form. But there are a wider variety of choices that you may want to play with:Use the distribute and collect features of forms in Acrobat and Acrobat.com.  This gives an automated way to bring all of the data together for you.  You can see this at http://formc...

Yes, integrating LiveCycle services, whether reader-extending a form/document is easy.  I'd suggest reader the LiveCycle technical white paper, especially the section on invocation on page 7; my guess is that web services would probably be the easiest. I'm assuming that you're just talking about the...

Below is an email I received from one of the Adobe/SAP developers.It sounds like you are trying to use Designer in stand-alone mode to create a PDF that you are then testing in your system without direct access to your SAP system.  That’s not going to get you where you want to go. To begin with, you...

SAP was the last, I hope, detail needed in this.SAP's Interactive Forms by Adobe (IFbA) has reader extensions built into it.   That will be how the form, provided it is not a dynamic form as has been related in previous posts, can get reader-extended.If you're not successful with this bit of info, p...
