Trans Replication is failing with error while adding the subscription

Error:  “The article ‘(null)’ does not exist.”
This seems to be know issue when there is difference  is number of article between sysarticles and msarticles.
– select count(*) from sysarticles on publisher
– select count(*) from MSarticles on distributor

Once you get the articles which exists in one table and not in other use exec sp_droparticle to remove that article and add it back using exec sp_addarticle

Note:We might get this error if we have two tables with same name in databases with case sensitive collation and replicate them (Ex: table and TABLE )
