Summary:

Approval rules based on Document Entry name don't seem to work, even though the option is available in BPM

Content (required):

I tried building simple approval rules for project expenditure batch approval based on Document Entry name rather than Document and the batch keeps failing in error - is it supposed to work? was anyone successful in creating this king of approval rules?

P.S it works fine when defined by Document name
