That is why it is important to understand them theoretically so that you can take advantage of them when the time comes. We can verify the absence of pushdown problems in rsrt by displaying the statistical data of our query (article to be published soon).Īggregation exceptions are simple to understand and can be very useful when used properly. The pushdown of the aggregation exception can be done in HANA once all these conditions are validated. In the composite provider, it is possible to check the "User Confirmed Referential Integrity" flag which allows it to make a join with the SID base table. Best practices for achieving optimal performance in SAP HANA SQL in SAP Business One, version for SAP HANA add-ons include all SQL statements and scripts that you use either in the SAP HANA database or in the add-on codes. SIDs are not processed in the target field. Best practices of special SQL grammar in SAP HANA, for example, stored procedure, cursor, temporary table, and so on. (For more information on CMP problems, please read this SAP wiki )
Otherwise, a CMP problem will prevent the pushdown. NVARCHAR, NATIONAL CHARACTER VARYING, NATIONAL CHAR. If an InfoObject is used in conjunction with another InfoObject as a reference feature, then both InfoObjects must be mapped to the set of sources used in the query. If you do not specify n, the default is an unsized NCHAR value. We load the data in a field based write optimized ADSO and want it to be loaded and activated in a standard ADSO with InfoObjects and changelog.
The reference feature(s) have CMP problems (compounding problem). For the example we created a sample file with invalid characters ‘’ and ‘’ in record 2, 4, 5 and 6, and a non-printable character Tapstop in record 7. The expected result after the join is 10 and not 20 this can be achieved with the Analytic Engine.
