Currently AttachContent smart shape will look for the attachments in Rule-File-Binary class. Does Pega has any plan to extend this to Link-Attachment class too? This will help to add attachments from Link-Attachment class to a work object.
With current implementation of attach content we can only attach files only from binary table. If we have something in attachment class we cannot use this smart shape.
The class cannot be Link-Attachment but instead it can be a Data-WorkAttach-File. I am assuming even the customer is looking for this as he would like to reuse the exiting attachments which are already made to a case.
The use case of AttachContent smart shape was to auto attach a file which is already in the system. And that use case would need a Rule-File-Binary only, so that was the reason for this feature.
This is not a bug but can be be an enhancement. If there is a business use case from the customer for making an existing attachment to be linked to another case we can add this as a feedback item and we can take it as an enhancement.
I agree to refer Data-WorkAttach-% class (can be a file, url or anything). I was working on a POC and found that this need to be enhanced with attachments table also. I agree this is not a bug but should be an enhancement. If you take any example for adding an attachment to a case and sending it in email, this will not help (if my attachment is in attachments table not Binary table).
What is the process to request it for an enhancement.
