Unable to delete Parameter Set from Designer

[ds_teg]

Hi all,

Just wanted to know what is the table name in shared metadata repository (XMETA) which stores information about Parameter set.
For example all the datastage jobs are stored in DS_JOBS, routines in DS_ROUTINES, containers in DS_CONTAINERS

This is because I need to edit an parameter set in my project which can't be edited (read only).

I tried to overwrite the dsx code of the same paramset with an editable copy but unable to do it.
