livecycle combine two documents together

You cannot combine XFA forms (that's the type of form you create with Designer). You might be able to combine the XML structures from both forms, but this is something for an expert user, you need to know how XML and XFA works in order to combine the data in a meaningful way.

I know I can import the catalog pdf (20 pages of images) as artwork background. But is it possible to add the purchase order form example provided by livecycle to the end of the imported file?

Basically, my requirements is add checkbox to the catalog pdf file, so when customer read through catalog file, they check product, then it automatically filled out the purchase form at the end of the document.

I'm really new to livecycle, only has two days playing around.

Thanks.

Again, you cannot combine XFA forms. If you need the functionality of the order form, you can bring it over piece by piece: You can select all the fields, copy them and then paste them on a new page in the catalog form. In addition to that, you would also have to bring over any JavaScript that is associated with the order form.

OK. If that's only way, then I will copy and paste them.

Now the first problem I encountered is after I import the catalog pdf, I can't insert new page,  "New Page" is grayed out.

Also if I am able to figure out how to implement this eventually, I can't reuse the purchase order form again next catalog, right? Since it seems like if I want to replace artwork, I need the same pages, which is not possible, since each catalog will be different.

What is the best way to accomplish the task? Some other PDF program?

I have not used Acrobat either, only reader, so do you think acrobat acroForms will be able to achieve my goal? add checkbox beside each product in the catalog and when user click on them, it automatically fill in the purchase order form for them at the end of the catalog? If so, then I will explore that option. Thanks.

I've done a project like that for one of my customers, using just the features in Acrobat. However, it was not straight forward. You need to really dive into the AcroForms API, including JavaScript. It may be cheaper for you to have this solution custom developed for you.

once it's custom developed, will it be reusable? and where to find such service? Thanks.

It depends on how it is developed. My form was reusable (only the catalog pages had to be replaced, the order page would automatically "adjust" to those changes). You can find a developer who is familiar with the Acrobat API for example on these pages:

Not all these experts are software developers (I am one, and as I mentioned, I've done work like this before, you can find my email address on my profile page).
