Key figures, for which the aggregation is set to No Aggregation, are not supported. Compounding is not supported: There is no attribute in the SAP HANA view, which represents the chained value of an InfoObject with compounding. Date conversion and alpha conversion are not supported. BW hierarchies are only available in SAP HANA views for InfoObjects. To use a hierarchy: A SAP HANA view must have already been defined for the InfoObject, on which a hierarchy is defined. The CompositeProvider must not have any ambiguous joins. The query can only comprise elements that are supported. More information: Supported BW Functions; This query. Key figure is not added by bw generated analytic view of the world. Sep 23, 2019  Very often I hear that BW is lacking a global key performance indicator (KPI) repository. It was for a long time already possible to create a calculated key figure (CKF) or restricted key figure (RKF) in BW on InfoProvider level. One could reuse them on different BW. The calculated key figures (CKFs) and restricted key figures (RKFs) defined on the SAP BW models are not created for the generated SAP HANA models. In this case, you can create an RKF as restricted measure in the generated analytic view. For CKF you can create calculated measures in the generated calculation view or analytic view.

Apr 06, 2020 Welcome to the OpenSSL Project. OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit for the Transport Layer Security (TLS) protocol formerly known as the Secure Sockets Layer (SSL) protocol. When a release is created, that branch is forked off, and its changelog is also forked. For example, none of the changes after 0.9.8n appear in the other logs, because 1.0.0 was created after that release and before 0.9.8o.
