Hi Martin,
according to note #1062188 you can ignore this warning.
Please proceed as described afterwards:
According to unicode conversion guide, 3.1 Additional Preparation Steps, error "1EED: DD sources table xxxx could not be read" can be ignored.
Please check if there's any content left on the database to make sure these tables are obsolete. If you do not find contents, these tables should be removed as of Unicode conversion guide chapter 2.1.6:
If you want to exclude a table from export after the Consistency Check,
- Drop the table from the database.
- Delete the table entry from the nametab tables DDFTX, DDNTF, DDNTT on database level.
- Reset the table in the Consistency Check.
A better choice for 2. is to remove nametab entries using function module DD_NAMETAB_DELETE via transaction SE37.
Afterwards please run report RADCUCNT again with variant UNICODE-02.
Therefore please execute steps 2.), 3.) and 4.) of the resolution part of note #1865781.
Cheers,
Andreas
