Local File System Attributes for Cross System Dumps, and effects with umask

I have a requirement from the development teams to allow MDM to dump, and PI to pick up (and archive) from the same locations. Currently accounts are set with umask 0022 (as expected).

Are there any repercussions from setting OS umasks to 0002 to allow the MDM and PI os accounts from writing?

Is there a better way to handle this within SAP, or should it be kept as an OS mask task?

(note these will be NFSv3 mounted, thus not using setfacl for launch masking etc).
