When you read the long text, it says to look in those notes. I don`t
know anything about this special module but as far I as understand the
note, there are two "versions" of REM:
- a "core" version (Classic - which you are trying to start)
- and an extended version (which is part of the EA-FIN extension).
Note 443311 (excerpt):
The functions of SAP Real Estate Management available in Releases
4.0B, 4.5B, 4.6B and 4.6C (referred to as `RE-Classic` in the
following) are still available in the core of SAP ECC. For
RE-Classic, SAP focuses on the stability of the product. Further
developments for RE-Classic are not planned. Refer to Note 448973
for the compatibility of the add-ons for the land use management and
the condominium owner management.
As of Release 1.10 of SAP R/3 Enterprise Extension, SAP delivers a
new Real Estate Management with extended and more flexible functions
(referred to as `RE-FX` in the following). Functional enhancements
were made in Release 2.00 of the SAP R/3 Enterprise Extension. Since
the converions of SAP R/3 to mySAP ERP, RE-FX has been further
developed in an extension of SAP ECC. For details on the RE-FX
functions in specific releases, refer to Note 517673.
So you either
- need to migration RE-FX (which is part of the financial extension)
- or deactivate that extension and use the Classic version.
