Hi Vignesh,
Do you know exactly where your master data which is coming from PI/XI is storing from SAP Sourcing side? Is it is Sourcing local directory or in FTP server. Please get this information from your PI consultant if you do not have idea on this.
And next point is check with your BASIS team to know the exact full path to those directories to use in schedule tasks.
We normally stores master data in local directory of SAP Sourcing.
Hope this helps.
Regards,
Gurvi.
