13 Decomposition

Decomposition is the process of volume optimization of high-volume accounting journals done in the interest of volume and performance. Events and Journals are two important factors of information on which Decomposition works. Decomposition is done to journals that are received from Oracle Fusion Cloud ERP and is performed by BCE based on grouping information that is maintained in the FSDF-AHCS INT i.e., Data Foundation integration with Accounting Hub (Oracle Financial Services Accounting Hub Cloud Service Integration for Banking). Due to this dependency with FSDF-AHCS INT, it is recommended that the Decomposition feature should be used together with the Oracle FSDF-AHCS INT application.

Decomposition will only cover ERP journals that are built based on information published via OFSAA FSDF-AHCS integration. The Decomposition results will be in the FSI entity - FSI_DECOMPOSED_FAH_JOURNALS. The ERP journals that are not built based on information published via OFSAA FSDF-AHCS integration and those from any other source will not be picked or processed by decomposition.

From version 8.1.1.1.0, the application will only consider journal information in FSI_DECOMPOSED_FAH_JOURNALS when it computes balance information. The primary intent is to support ERP interface. Grouped and non-grouped transactions and journals will be in scope.

It is technically possible that there are journals from external sources that are not published to ERP but need to be used for balance computation as is. It is also technically possible that ERP journals will include those based on transactions or journals not published via OFSAA FSDF-AHCS integration. These journals have to be identified based on filter parameters and posted into FSI_DECOMPOSED_FAH_JOURNALS through data movement via a process connector or T2T configured (as shown below) during the implementation.

Figure 13-1 Implementation

From version 8.1.1.2.0, a Table to Table T2T_STG_PASSTHROUGH_JOURNALS has been introduced to process pre accounted pass through entries from non Oracle ERP sources. The pre accounted pass through is generated only when the Data Origin is set as "PT".
