Please follow these guides:
The Guide is here J:\IT Guides and Forms\NetSuite Guides\PDF Version\NetSuite Adding MSDS sheets.pdf.- The excel template is here J:\IT Guides and Forms\NetSuite Templates\MSDS Template.xlsx.
The template will need completing as follows:
This allows a copy per country and the actual file also needs the country prefix too, I've started updating this in the excel file, as Bernie advised all names for the country files need to be in the same template file. Then the actual files on the J Drive also need to have country prefix added, which i've also started working on.
Once the files are ready, a URL can be provided by the NetSuite team and added into Magento by the Developers for customer access.
