Why the value of field ckis-elemt is empty?

Hi expert,

After I use t-code:ck40n to do costing run. I checked the result in the table ckis. There are some item elemt field value is empty.

If the material has no accounting/costing view. Does it effect the ELEMT value be empty?

Why the value of field ckis-elemt is empty? How can I correct this kind of data about the field elemt is empty?

Thanks a lot.

Best regards,

Eric
