TO is ‘Target Organisation’ which means your company. There should always be a default TO and this should be the primary site of your company.
It is possible to have more than one TO for example to reflect multiple divisions of your company. Different TO’s can have different addresses, contact names, responsibilities and logos etc.
A key way multiple TO’s are used is in document production. For example if you are responsible for producing documents, such as Safety Data Sheets, from multiple divisions or companies you can reflect the individual company logos and contact details on the documents.
