When populating the Spreadsheet, please note

• The Reb columns indicate vital and essential information for the system to serve well;
• The Green columns are very important but the column works with codes as indicated on the Spreadsheet’s KEY page;
• The Black columns need information, but can be NULL if no information is to hand.

When done with inserting the data, the one can use the ‘Search’ and ‘Replace’ feature in Excel to fill the blank spaces with NULL.
