Derivation Rule

Hi Everyone,

when  I  try to create a Derivation rule with name DERIVE_CCTR,  I am getting the error as 'DERIVE_CCTR' had already been used. But I had already deleted the derivation rule which I had created earlier.I had also tried to delete the derivation using the Program “FDT_DELETE”(Overriding the Authorization issue), even then the Derivation rule is not removed from the system.

Any inputs on the same can be helpful.

Thanks,

Anusha
