Hello Abdellatif,
Please login to system using DDIC/000 and find the corresponding tables in E071 table. Check in which package these tables are delivered.
Change the "LOCKFLAG" from 2 to 3 only for those entries.
You can't edit the table entries manually you need to write Z report to update them.
But please first try to activate the tables on logging to system. It's not advisable to skip Activation phase.
Regards,
Surojit
