Hello manjit.1486 , 
 Does this button trigger a Start process? If so I would recommend you to use a Record/Related actions to perform this and try using a User Input task where the user has a summary of what kind of document and what data is there and so on, add a document download link using a!documentDownloadLink() pass your generated document as the value here. I guess this would help and this is what you were asking for. If not please ignore.

 You wouldn't use a!startProcessLink() for this. You'd use a!StartProcess(), run the process with chaining enabled, and pass the generated document Id back into your interface.

pleeeeeeease use "insert code" for code of... any length 
 you would need to add the "onSuccess" parameter within your a!startProcess call in order to call the generated document ID back into your interface (just store in a local variable, etc).

You need to read the details in the rule description for a!startProcess - granted it's not SUPER well explained at a surface level, but it's also not that hard. The highlighted snippet is what you're missing in the above iteration:

Make sure you account for the fact that the Doc ID will be blank at first. It will be easier if you use a!richTextDisplayField() (i recommend nobody EVER use a!linkField() at this point, it is essentially deprecated by the existence of the Rich Text field) - the benefit here is you can either hide the field entirely and/or disable the link while the local variable containing the document ID is still blank.

Mike Schmitt · Answer

You have a double negative here: 
 
 Essentially this is saying to show the rich text item only when local!docId IS empty. 
 You should be familiar with a!isNullOrEmpty() and its opposite, a!isNotNullOrEmpty() - you would use one or the other of these, but you should never really need to wrap either, especially the latter , in the not() function like you've done here.

Mike Schmitt · Answer

This is all you need. The "label" parameter in document download link is irrelevant when used in a rich text item, which just uses the value you place in the "text" parameter. I've removed everything irrelevant here and fixed the aforementioned "double-negative" error. 
 a!richTextDisplayField(
 value: a!richTextItem(
 text: "Dowload Document",
 showWhen: a!isNotNullOrEmpty(local!docId),
 link: a!documentDownloadLink(
 document: local!docId
 )
 )
) 
 
 If you want to go slightly fancier you can make use of the super flexible nature of being able to stack multiple a!richTextItem() elements inside one Rich Text Field, and add one that shows up specifically as a placeholder while the Doc ID is still blank: 
 a!richTextDisplayField(
 value: {
 a!richTextItem(
 text: "Dowload Document",
 showWhen: a!isNotNullOrEmpty(local!docId),
 link: a!documentDownloadLink(
 document: local!docId
 )
 ),
 
 /* show a special placeholder while local!docId is still blank: */
 a!richTextItem(
 showWhen: a!isNullOrEmpty(local!docId),
 text: "(No Document)"
 )
 }
)
