Validation Rules not working for Copy DMP

Hi All,

I have created validation rule in UJ_VALIDATION.

As per configured validation rule,working fine with Input form.(When I tried to enter the data with input form,throwing out error).

But validation rule is not working for Copy DMP.For the same data intersection I am able to copy the data.

Validation rule is not applicable for copy DMP and calculationDMPs?

Anybody experienced significant negative impact on performance while saving the datat?

Thanks,

Manohar
