BW InfoObjects modeled by CDS Views

Similar to BW, InfoObject in CDS could be:

  • Key figures / measures
    Fields defined with annotation @DefaultAggregation: #SUM,  #MIN or #MAX  or @Aggregation.default: #SUM,  #MIN,  #MAX or #NOP,.
    Usually they are directly defined in a "@Analytics.dataCategory: #CUBE" CDS views.
    If it is defined in a "@Analytics.dataCategory: #DIMENSION" CDS views, it is a key figure attribute of the InfoObject.
    By using @Aggregation.default: #NOP, key figure can have default aggregation NO2.
  • Characteristics:
    All other fields, either without any @DefaultAggregation/@Aggregation.default annotation, or with @DefaultAggregation:#NONE
    If the data type of the field is a key figure type, such as CURR, QUAN, DEC, FLTP..., it is not supported for a characteristic. In this case, the field is simply ignored before Note 2771186 and 2778887. After this note, the field gets a default NO2 aggregation and becomes a NO2 key figure. Explicit set @Aggregation.default:#NOP is not recommended as it is not supported in SADL service.Thus please just remove the @DefaultAggregation/@Aggregation.default annotation.
    Long timestamp (data type TIMESTAMPL) field is not supported. The field is ignored. (Note 2737769, 2887459 )
    Fields longer than 250 characters are only considered up to the first 250 charaters. See Note 2852065.

DefaultAggregation Annotations

Characteristics

Features:

Key Figures

  • Only support default aggregation: SUM, MIN, MAX, NOP. 
  • To use other aggregation such as AVG, please use formula exception aggregation in a CDS query.
  • Semantics needs to be defined for amount or quantity key figures
  • In a CDS query, key figure can't be used in CASE statement when clause as a condition. Because filtering on a key figure is not supported in Analytic Engine.  Please use a formula with IF clause instead.
  • In a dimension CDS view ( with annotation @Analytics.dataCategory: #DIMENSION), no key figure fields can be defined as key fields. Only characteristic fields can be key fields.
