in SARI you just see the few fields that are contained in the infostructure.
the info structure is nothing else than a table in your SAP system which has beside of some important data fields that are used for quick info a field with information where the full record can be found.
if the archive file is not accessible anymore (e.g. paths got changed, physically removed from storage system) then you cannot display the data in VA03 nor in ALO1 nor in SARI by double click.
Goto SARA and check behind the administration button if your archives are still accessible.
