Fact Templates for Siebel Data Warehouse Customizations

---

This template shows how to attach an existing dimension (account dimension) to a fact (asset fact).

CustomTemplateSDE_AssetFact

Using this SDE mapping, the staging extension table for the Asset fact is populated with incremental data. The different transformations are the following:

• SQ_S_ASSET. Selects the OWNER_ACCNT_ID that will ultimately be used to join with the account dimension in the fact. Note the extra where clause joining to the incremental image table.
• EXPTRANS. Gets DATASOURCE_NUM_ID using lookup LKP_DATA_SOURCE_NUM_ID from table W_PARAM_G. This table is populated in the beginning of the session by the DAC server.

Finally, the FK_01_ID field of the extension stage table W_ASSET_FSX is populated. All the system columns are also populated.

CustomTemplateSIL_AssetFact

This SIL map is used to populate the final extension table for the Asset fact. The different transformations are the following:

• SQ_W_ASSET_FSX. Note the SQL in the override. This joins with the dimension table W_ACCOUNT_D to get the ROW_WID of the dimension row to be populated in the foreign key id column of the extension table.
• LKP_W_ASSET_F. Retrieves the ROW_WID of the parent fact table W_ASSET_F.
• LKP_W_ASSET_FX. Gets the Insert/Update flag that is used by the update strategy to find out whether to insert or update this row.
• EXPTRANS. Gets ETL_PROC_WID using the lookup LKP_ETL_PROC_WID from table W_PARAM_G. This table gets populated in the beginning of Refresh Siebel DW. Also generates Insert/Update flag based on the previous transform LKP_W_ASSET_FSX.
• UPDTRAN. Updates or inserts a row based on the flag.
