How to stop copying accounting key when copying pricing condition

[gopalkrishna_baliga]

Hi Experts

I have a scenario where in I have to copy a pricing condition.

I am doing this in user exit include RV61AFZA.

Here I am changing the cndition type in KONV.

This works fine but accounting key (KVSL1) is getting copied from source pricing condition to new pricing condition. How to prevent it?

I tried clearing it the same user exit include program KONV-KVSL1 = ''. But then I get "Error in pricing determination".

KIndly help.

Thanks & Regards
