Hello Community!
We built a custom cds root entity which gets its data from a remote client proxy. Now we want to use this custom entity as a data source for other views or as association/join in other views. Every approach I tried failed so far - is there any solution to that?
Use custom entity as data source:
define view entity I_Entity2
as select from I_CustomEntity
Error: Entity "I_CustomEntity" cannot be used as the data source
Use custom entity in join statement:
define view entity I_Entity2
as select from I_Entity1 join I_CustomEntity ....
Error: Entity "I_CustomEntity" cannot be used as the data source
Use custom entity as association:
define view entity I_Entity2
as select from I_Entity1
association [1] to I_CustomEntity as _Custom ...
{
_Custom.Field1
}
Error: Target of association _Custom cannot be an abstract/custom entity
Hello,
you cannot use custom entities as data source. You can just integrate/expose it as an association without accessing a field. For example:
define view entity I_Entity2
as select from I_Entity1
association [1] to I_CustomEntity as _Custom
{
_Custom
}
