Hi there,
I'm not sure if this is possible, the DTP usually reads the data between the PSA and the Datatarget with 7.x functionality.
Is it necessary to skip the PSA? Why do you want to do this? What options do you have in the DTP settings for skipping the PSA, I checked this on my test system and I believe it is necessary to load to the PSA firstly.
You will see the technical name for the Source System in table LOGSYS, or perhaps SLOGSYS, check this out on your system. Also, you can check the technical name of the Source System in the Source System tree in RSA1.
Again I'm not sure you can do this without the PSA,
Thanks,
Colm
(I'll be intersted to know how you acheive this if you do manage to get it working, thanks)
