SLT system cleanup

Hi,

We are replicating data from CRM to SAP HANA using SLT.

We done a lot of development on SLT (created a lot of configurations, deleted them, then recreated them again, e.t.c).

But as SLT is not deleting all objects compleatly we have a real mess now in system. For instance we have only 5 configurations working now in system, but we have already used number 155 of mass transfer. Because of that we are expiriencing some other issues.

Is there some wise way to do system clean-up?

Thanks in advance,

Markus
