A developer wants to use a CROSS JOIN in a CDS view running on SAP NetWeaver 7.40 SP08. Explain whether cross join is supported in 7.40 SP08 and what release introduced it.
| Checked | Without skill | With skill |

Use this skill when creating ABAP CDS views or view entities, defining associations and cardinalities, adding UI or semantic annotations, implementing DCL access control, handling currency/unit fields, troubleshooting CDS compiler errors, or comparing classic CDS views with newer view entities.

This skill covers CDS features from 7.40 SP8 through ABAP Cloud. Key version boundaries:
| Feature | 7.40 SP8 | 7.50 | 7.51 | 7.55+ |
|---|---|---|---|---|
CDS View (DEFINE VIEW) | x | x | x | x |
| CDS associations, parameters, built-in functions | x | x | x | x |
CDS Table Functions (DEFINE TABLE FUNCTION) | x | x | x | |
| CDS Access Control (DEFINE ROLE / pfcg_auth) | x | x | x | x |
| CDS Access Control (implicit evaluation) | x | x | x | |
Session variables ($session.user/client/system_language) | x | x | x | x |
@Environment.systemField annotation | x | x | x | |
UPPER/LOWER functions | x | x | ||
$session.system_date | x | x | ||
CDS Metadata Extensions (ANNOTATE VIEW) | x | x | ||
| Cross Join in CDS | x | x | ||
CDS View Entity (DEFINE VIEW ENTITY) | x | |||
New cardinality syntax (to one/to many) | 7.57+ |
On a 7.40 system: Use DEFINE VIEW (not DEFINE VIEW ENTITY). CDS table functions
are not available before 7.50. Basic DCL (DEFINE ROLE with pfcg_auth) is available
from 7.40 SP08, but implicit role evaluation in ABAP SQL requires 7.50+.
$session.user/client/system_language are available from 7.40 SP08.
