Hello,
it is less complicated.
If you have an existing CM25 profile and a layout key where you want to add a new custom column:
- Structure CYUSER, Include CI_CYUSER: add your new custom field, DO NOT forget to define a data/component type for the field in the structure (see sap note 590880), without that it will not work!!!
- User Exit CYPP0005 / CYPP0002: enhance include to determine value for new field in structure
- Transaction CY38: enhance desired layout key of your profile with new field by choosing structure USER.
