Sapscript, OSS Note 1123823, SAR File attachment

Hi Experts,

I'm basically implementing OSS note 1123823. One of the solution provided is to create 3 new sapscript forms. These forms are attached via *.SAR file. I managed to extract 2 files (K238832.L9C and R238832.L9C) from that using sapcar. Right now, I am clueless what needs to be done now. I tried uploading these files via RSTXSCRP but I can't seem to make it work. Do you have any idea how can I implement this? Thanks!
