If the "RECEIVE SYSMODS" part of "RECEIVE NETWORK" or "RECEIVE FROMNTS" completed successfully why would it matter since you don't need the package after that. If there was a problem with RECEIVE, DELETEPKG isn't going to delete it anyway. The only reason I keep stuff out there for 90 days are for CBPDO orders of ServerPacs in case someone lets it sit for a while or wants to start over. Otherwise, the SMPNTS usage is for maintenance where people "receive it now" and it never gets touched again. >So some files might not need to be re-transferred.

In the case of RECEIVE ORDER, I don't think you can do a transfer only and it wouldn't be selected the second time anyway since SMP/E would know it is already received.
