Hi Sowbhagya,
the best thing you can do is to implement the latest patch SAPK-90119INSAPSLL (or SAPK-90116INSAPSLL as proposed). If you want to implement only 2157094, you have a lot of manual work to do.
As far as I know there is no other structure and transformation to load a XML file for SPL purpose in GTS.
Hope you can now get along with the informations
Regards,
Thomas
