Validating that a document is attached with the Approval

[JVOGEL11]

I would like an approver to attach a document with their approval.  If they hit 'Approve' without the attachment present, then it should prompt a message to add the attachment.    I also need this to work only when the 'ask for approval' is invoked from a particular flow (e.g., Process Shop Request).   I am thinking this might be a business rule or client script, but not sure the best approach.  Any thoughts are appreciated 🙂

Sujatha - thank you.  The script might solve half my problem.   I am thinking of applying this to the table: sysapproval_approver (during the approval with the approver).  However, I dont need to have the script applied to every approval, just those where the approval applies to specific type of service catalog item category and flow.   I don't see any fields in the sysapproval_approver where I can identify what category condition the UI script can be applied.  What would the script look like to check the item category that is related to this specific approval?   Would I be able to dot-walk in some way?

@JVOGEL11 : If I had understood it, you have a approval record as below and the field "document_id" references to the RITM record which inturn holds the field "Item" details.

Hello,

You can create onsubmit client script and use GlideSysAttachment API to check existence of attachments on specific record.
