I don’t see any standard functionality to Batch Close PO lines. However this can be done through a simple migration job or enabling a custom RMB option to Purchase Order Lines window where  you can filler the PO lines with status “Received” and then close. 

@Rasika Lakmal I am using Aurena, Do you happen to know how I can add this function like the RMB  onto the purchase order lines page? I tried adding from the list of commands but this specific command does not show up on the page designer.

@mmoss As you’re in Apps 10, you could add the custom RMB option to IEE client and then need to configure through page designer in Aurena (I have never tried this in Aurena).

@Rasika Lakmal I am attempting to create the RMB but I have never done this. Would I use action type state Machine? What is the state machine action parameter? Thanks

I have suggested the custom RMB button that will require the technical configuration.
