...and? It didn't work?
RFDLKBLE will simply delete the data from the tables; there is no reconstruction process here. Technically speaking, you can do the same by simple going into the table and deleting the line.
Again, though not a fan of 'unconventional' intervention in the system, I see no wrong in doing so, if:
a) there is full understanding of the actions applied
b) tests are duly performed
c) results are satisfactory
