Hi, there are a number of options for this depending on specific needs.
PDF Forms
If you have access to Acrobat, you can create a PDF template using form fields as placeholders for the values. This can be uplaoded as a PDF Form Asset in Build Studio, and you can then map Properties of an object to each placeholder. A Rule can then be used to create a copy of that PDF with those form fields filled in, and saved to the record.
Pros: Relatively simple to use. Fixed layout, a pro if that’s what you need.
Cons: Requires Acrobat to create the templates. No support for images. Fixed layout, a con if you need a layout that caters for content of varying lengths nicely. No lists/tables, single values only.
Templates
You can create templates using a WYSIWYG editor, giving you control over formatting and styling, and include placeholders for record data, including images and sub pages with simple widgets. A rule is then used to generate that template as HTML or a PDF while populating it with a specific record’s data.
Pros: Flexibility over content. Can include listings, and content can flow/expand. Can include subpages for more control.
Cons: Not a fixed layout, a con if you need every document exactly the same.
IDP Document Generation
Newly added in 25.3 the IDP Document Generation features brings some of the previous OPA functionality into Build Studio. You can create document templates in various formats in Word or PDF which include text placeholders tags, which are then mapped to fields in Create. Similar to PDF Forms mentioned above, but more advanced. Using rules you then generate the documents using those templates.
Pros: Support for multiple file types. Supports images and lists/tables. Doesn’t require Acrobat specifically.
Cons: Not a fixed layout, a con if you need every document exactly the same.
