Delete Entrie Transaction Type(YMCR, YMHF )

Hi Experts,

I want to delete the complete Trasaction type YMCR, YMHF so that i can again create the copy of it with standard setting and make use of this transaction types. I have tried updating it with Solman_Setup but it is giving Dump while Updating. So is there any way we can Delete Entrie transaction type and create Fresh Ones.

I require this beacuse i dont have any names left to create it into the system. i have Z, Y, ZZ ,YY . So delete is necessary.

Regards,
