Hi Chow,

Thanks for posting on PSC.

I have found similar requirement on PDN,

Please follow steps to convert Correspondence rule to PDF,

1. Convert the correspondence rule to an HTML. 

2. The output of the property-set-correspondence should be framed as an HTML ( read the outputfromcorr from clipboard page, use appendString(outputfromcorr) in Html stream.)

3. Then, the output of the property-set-HTML can be used as the input to HtmltoPDf.

You can refer it, for more detailed descriptions:-

Hope it helps you in implementation, kindly notify.

Regards,

Asif
