I meet with the error below: Characteristic of class CRM_L_DOC is not valid
I debugged a little and found it is caused because the content management code regards “CREATED_BY” field as read only ( protected field ) if internal mode is inactive.
I use where use list on the field internal_mode and found the FM below could activate internal mode with 02 passed into.
After I call that FM in my program, the error is gone and attachment could be created. Unfortunately, I still could not specify the created_by field, I find it is always filled as sy-uname in line 298.
