Add ernam to 2lis_02_itm

Hi all!

I would like to add the field ernam (created by) to 2lis_02_itm.

I checked in tcode LBWE but the field is not available in the communication structure MCEKKO. How can I add this field to the communication structure so that it will be available in tcode LBWE?

Thanks!

Regards,

Linda
