Integration Models - CFM1 in R/3

Hi, we found a number of Z* variants for our program RIMODGEN (transaction CFM1, generate integration models). We figured out that these come from clicking the save button after clicking execute and seeing the number of objects selected. We thought we need to click save in order to have the selection automatically loaded into RIMODAC2 ( transaction CFM2, activate/deactivate integration models) to activate. However this is creating the Z* variants. We found that this still will load even if we dont click save. But aside from that, we want to know if we can delete these Z* transactions without any repercussion.

Thanks.
