KB8476: How to edit e-mail attachment names and extensions using both static and dynamic content via control documents in MicroStrategy Narrowcast Server 9.x?

E-mail attachment names and extensions can be modified or personalized using both static and dynamic content (via control documents).
 
Here are some examples to accomplish this new feature. Create a new Control Document with the appropriate syntax below:
 

• ChangeAttachmentName = 'My Attachments.txt=Sales Report.txt'
• ChangeAttachmentName = 'My Attachments.txt=Sales Report.csv'
• ChangeAttachmentName = 'My Attachments.txt=Sales Report.txt|My ExcelAttachments.xls=Profit Report.xls'
• ChangeAttachmentName = 'My Attachments.txt=Sales Report.txt|My ExcelAttachments.xls=Profit /Report.xls'

Please note the following:
 

• Each entry name is case sensitive, for example: ChangeAttachmentName
• To separate multiple documents use the '|' (pipe symbol)
• Each document names is case sensitive
• Any invalid characters in the new name are replaced with the underscore character
• The renaming of two attachments into the same new name is supported
• The renaming of non-existing attachments are unaffected
• The creation of more than one ChangeAttachmentName entry in the control document fails the service
• The renaming of a new document into an empty name will automatically cause the document to generated new name
