ER : cannot drop one table

Good morning/evening, We use ER to replicate whole databases between servers: - primary (root server) : IDS 9.40.UC2 - secondary (leaf server) : IDS 9.30.FC3 Now we want to drop and recreate one replicated table, but we can not drop the table on the secondary server: we get the error -19816. Of course, we had previously stopped and deleted the replicate that manages the table. In a second step, we have even stopped completely the replication (cdr stop) on the secondary server. In both cases we get the -19816 error. Have you any idea about this problem ? Thank you, Philippe
