The length of the ‘filteringattributes’ attribute of the ‘sdkmessageprocessingstep’ entity exceeded the maximum allowed length of ‘100’


While developing a plug-in for CRM 4.0 triggers can be set when the plug-in can be set off using the Plugin Registration Tool.

When too many triggers are selected the following error will occur.

Unhandled Exception: System.Web.Services.Protocols.SoapException: Server was unable to process request.

A validation error occurred. The length of the ‘filteringattributes’ attribute of the ‘sdkmessageprocessingstep’ entity exceeded the maximum allowed length of ‘100′.

What is de filteringattribute attribute?

While registering a plugin trigger in the CRM database the [<OrganizatioName>_MSCRM].[SdkMessageProcessingStepBase] table is updated.
For every plugin step a record is created in this table.
One of the attributes in this table is

[FilteringAttributes] [nvarchar](256)

During the registration of the plugin step the MetadataSchema is checked and validated a.o. the MaxLength of this attribute.

SELECT Maxlength
FROM [<OrganizationName>_MSCRM].[MetadataSchema.Attribute]
wHERE name =’filteringattributes’

By default the result of this query will be ‘100’. Strange of course since the database will allow to insert nvarchar strings up to 256 characters.

A solution could be

Update [<OrganizationName>_MSCRM].[MetadataSchema.Attribute
SET Maxlength = 256
where name =’filteringattributes’

If the MaxLength is set to more then 256 a SQL Error may occur since data will be truncated.

Note: After an update IISReset /noforce is required.

Note: Above customization is unsupported and you must take precautionary measure to make sure to avoid any problem with CRM system.
