Hi Anand,
Thanks for pointing out that ..But we have configured only one domain controller that is in production PSP and the trans dir resides in Production.and i said before that in transport tool parameters TRANSDIR is same for 3 systems..https://help.sap.com/saphelp_nw73/helpdata/en/14/c795388d62e450e10000009b38f889/content.htm this link is for connecting 2 separate domain controllers right? Do i need to change the current cts config and make one of the DEV or QAS in development server as Domain controller and try to link already configured PSP domain controller in production server ?
