Truncate TABLE PSA table-index part
I have a doubt about the truncate action on BW of PSA table.
To speed the activity and empty some tablespace I have truncated for example the PSA /BIC/B0000025000 and all table and index parts have emptied, so, on the contrary of disk space, the table part and index part from 00001 to 00050 for example are no longer used and the next uploads creates partition 00051.
The question is: I must drop all index and table part previously emptied?
If yes a must keep in mind some indications?
I could have some problem to leave this table and index part empty, for example about performance or inconsistence?
There is some contraindication to truncate PSA?
Can i use program 'RSAR_CLEANUP_PSA_DIRECTORY' to delete its?
Thanks for your help.
