Functionality

The function module RSDRI_INFOPROV_READ reads data from the InfoProvider whose technical name is specified in I_INFOPROV. Supported InfoProviders are currently InfoCubes, ODS Objects and MultiProviders.

Using the parameters listed below,

• restrictions can be defined for the data to be read,

• return types can be determined, and

• general conditions (authorization check, avoidance of program generation, and so on) can be specified.

Notes

A logical read access with RSDRI_INFOPROV_READ can contain more than one physical read access to the database. This is designated as a split. Splits may occur especially with MultiProviders, but multiple accesses through aggregate optimization or access to F- and E fact tables can take place with normal InfoCubes. Furthermore, results that are not completely aggregates can result in virtual InfoCubes. Therefore, setting the parameter I_USE_DB_AGGREGATION = 'X' does not guarantee complete aggregation of the result. Module RSDRI_AGGREGATE_DATA is useful to aggregate a table E_T_DATA.

Non-cumulative values:Non-cumulative values can also be read using

this interface. However, there is the restriction that only the non-cumulatives for the specified times (see I_T_RTIME) can be calcualted; Aggregation over time (such as LAST or AVERAGE, for example) cannot be calculated using this interface. Even when the time-reference characteristic is not explicitly requested, a drilldown is inserted internally according to this time characteristic. Thus it may be that no completely aggregated result table is returned.
