Answer : Incorrect syntax for INSERT using INNER JOIN

>>forgot FROM<<
Also your WHERE clause :)

Insert dbo.E_FINAL (TDate, TTime, ANumber, TCode, FieldCode, NewValue, IFlag, RCode, AS_400_UserID, ProductLoanTypeCode, NotUsed)
Select GetDate(), GetDate(), @AcctNumber, fc.FieldCode, @CaseNumber, 'I', '    ', '        ', '    ', '   '
FROM dbo.E_Field_FieldCode fc
WHERE fc.FieldName = 'CaseNumber'
