Follow these steps to include the No Valid Address flag in a Constituent Import:
  1. In the constituent Import spreadsheet, create a column for No Valid Addresses where the value is Y or T (Y=Yes, T=True) if the constituent has no valid addresses, or N or F (N=No, F=False) if No valid address should remain blank on the constituent record in Raiser's Edge.
  2. When importing into Raiser's Edge use the Fields tab to map the fields in the import file to the relevant fields in Raiser's Edge.
  3. For example, under Available Fields, select Constituent, Has No Valid Addresses where this field would be linked to the field in the spreadsheet that was set up in Step 1.
See the Import Table section of the Import Guide for the list of headings in the import spreadsheet:-
