Chandan, you would need to use usp_owned_resource in the maj file. The reason is this is SDM("usp_") schema, not overall ca("ca_") thing. These are the steps you would need to follow:
1. create a maj file in NX_ROOT\site\mods\majic folder,--for example, itamsdm.maj--with the statements I mentioned.
Please notice that this is just an example statement for those 3 fields you mentioned and you could add more to it.
2. recycle SDM...after this, they will be available in WSP right away. and for boxi sdm universe, you still need to follow
the standard procedure to add them to the universe, but these fields are available for you to add now.
