Yes, the issue is from SharePoint to Word. A formatting command for numbers (especially currencies) would be great.
InfoPath supports currency formatting of fields on display, SharePoint supports currency formatting of colums on display, Excel supports currency formatting of cells on display, but Word does not support currency formatting of content controls on display.
I'm going to emphasize content controls. There is a trick, or two, to format fields and cells in Word for currency formats but these don't work for content controls. The only data type Word content controls support formatting for is dates.
The blog post List fields + Workflow = controled Word document [SIC] outlines what I am doing, though I'd like to skip the intermediary list and workflow step and have qRules write fields directly to the document library. (Document libraries are lists after all. Fingers crossed.)
Yes, I'm holding MS to the marketing pitch of "no code" and "composite" solutions by building mash up applications using MS products.
