Can we use the Security ID for more than one contract with changed parameters.
Security Id created with tr. FWZZ is entry of your security parameters and conditions. Let's say if you have paper security you have to enter in FWZZ all data that is on paper/ in agreement. One security - one entry in FWZZ.
If you enter new conditions and parameters in already created Security ID. It will affect the previous entry in TS01. And it's not right.
So if you have another security - create another entry in FWZZ.
I hope i described the situation clear.
