Workflow Start condition not working

Hi Friends,

I have a start condition in my Custom workflow.

BO 'BUS2032' and the condition is SalesDocumentType = 'ZZZ' (Workflow should be executed only for Document type 'ZZZ')

Start condition is active (Checked in TCode SWB_COND)

When I evaluate condition with test data it is working fine. (Returns 'False' in case of any other document type and 'True' in case of 'ZZZ')

But, when I execute workflow it is not working. Workflow is being executed for all document types.

Please help me if any one has Idea
