Updating filtered replicated rows on subscriber fails

I have a merge replication scena开发者_开发知识库rio with 1 distributor/publisher and many subscribers. There are only a few articles which are unfiltered everything else is filtered by HOST_NAME() and thus creating distinct (nonoverlapping) partitions. I also tried filtering via SUSER_NAME() to no avail.

Filtering and distribution work perfect but updating on the subscriber fails with this error message:

Cannot update the column in article '%s'. The article has a value of 2 or 3 (nonoverlapping partitions) for the partition_options property, and the column is involved in a row filter and/or a join filter. In this situation, the column cannot be updated at a Subscriber or republisher; it must be updated at the top-level Publisher

The article it fails on has a partition_options-setting of "Nonoverlapping, single subscription". The SQL I tried to execute is a simple parameterized UPDATE of a few nvarchars and bits.

Anybody any Idea what I'm missing? It can't be far...

EDIT: SQL Server 2008 R2 btw.

I found it.

The Problem was that the update I tried to do (well Entity Framework in this case) was also including the column I used in the filter expression, so this update would change the partition of this dataset which is apparently not allowed.
