Need some more clarity on SAP Note: 2545209

Hi Team,

I am going through SAP Note 2545209 and came across one point, which is causing me confusion. Here is the solution from SAP Notes, which says as below, but the one that makes me confused here is that information structures will not change, and hence the display will work. As you can see below, 

Solution
Standard Existing Reports (enabled to read from archive) that were available in ECC and now available in S/4 can still display the FI data that was archived before the upgrade to S/4. This is because information structures will not change, and hence the display will work. However, any new report based on "HANA Live" CDS View, OData Protocol, or Ina Protocol will "not" be read from the archive.

This is applicable for all the releases in S/4.

So does it mean information structures will not migrate, thus they will remain unchanged, or does it mean they are coming as-is from old ECC 6.0, thus they are unchanged, so it will work without any issue?

If someone could provide more information, that would be great because scenarios may be different. Also, is that a green-filed or brown-filed approach? 

Thanks

Hello @ashish_pancholi 

The way I understand the note is:

• archive information structures are not touched by migration to S/4HANA; they remain as they were in ECC
• thus the old, proven FI reports can still read archived that through those structures
• the new, fancy reports based on CDS Views / Odata / InA are not reading archived data

I just wonder if SAP plans to provide access to archived data in those new reports at all and when.

Best regards
