Defects Code Group assignment level

Dear All,

I have 2 code groups e,g  DEF1 and DEF2 of catalog type 9 defects, DEF1 can only be selected at operation level defects recording using QF01 and on the other hand DEF2 is only available at Characteristic level defects recording .

I want both code groups at both assignments levels while doing defects recording through QF01.

thanks,

Zeeshan
