Can table STXH, STXL, STXB be reduced?

Hi All,

Currently my team are doing some analysis for archiving object BC_ARCHIVE.

We have done the testing for the archiving object.

But after testing, we noticed that there is still no significant reduction to the system size.

We discovered that the table STXH, STXL and STXB consumed a lot of space in the BC_ARCHIVE.

But during testing the size of this three table have not reduce.

I wonder, can we reduced the size of this three table thru archiving?

If not, could someone enlighten me why is it so?

All your input are absolutely helpful.

Thanks,

Still learning.
