Using InfoCube ZXX_XXX:

InfoCube ZXX_XXX cannot be deleted because of references

Deletion of 000000 TLOGO objects

Solution:
1) Delete the data from the IC.
2) search for the DTP, you will not find the DTP in the system, bcoz i had already deleted the DTP manually.
3) search for the DTP using the find(globally) button.
4) select it and delete the DTP.
5) next IC got deleted without any issue.
