Hello, I am looking to add a rejection reason field to expense reports that have been rejected, so the admin/ finance can see the reason the supervisor has rejected it, Does anyone have any ideas on how to do this?

I have done it 2 ways, 1 was to create a pop up window that requires someone enter a reason, this reason is then populated on a sublist for the record, very time consuming and detailed, I would have to dig through my notes to see if I can find the instructions. The 2nd way, which is much easier, is to create a custom field, and when the record is rejected, that field becomes mandatory. You can then use that field on a saved search for the admin or finance person.

I have used a custom record to hold the rejection reason. Then used this custom record type for all the approval work flow. Force rejecter to fill in the value of this custom record by using go to record workflow action. Then use a saved search for this record (filter = related record) and custom sublist in the transaction in question. Same custom record can be used for all types of transaction approval process - JE, PO, Requisition,. Invoice, bill, SO etc.
