05 Adding multiple sources
1. Add physical tables to an LTS or LT.
2. If data is not duplicated then that physical table can add to LTS or LT
(As a best practice add to LTS).
3. If data is duplicated then we need to add physical table to LT. In this
case we need to define content logical level. (It is used in aggregate
tables and partition tables chapters )
Note: To add Physical table to LTS, the adding physical table
and existing physical table of LTS must have direct join.
Process:
Step 1 : Import below tables into physical layer.
1. D1_PRICELIST.
2. D1_PROD_DIET_TYPES.
3. D1_PROD_SUBTYPE.
4. D1_PRODUCT_TYPE.
5. D1_SUPPLIERS.
Step2 : Create joins as per below.
1. D1_products.suppliercode = D1_suppliers.suppliercode.
2. D1_products.productkey = D1_pricelist.productkey.
3. D1_products.dietcode = D1_productype.dietcode.
4. D1_products.subtypecode = D1_productsubtype.subtypecode.
5. D1_product_subtype.typecode = D1_productype.typecode.
Step 3 : Mapping multiple sources to an LTS.
1. Drag and drop D1_PROD_SUBTYPE physical table onto D1_Product LTS.
2. Similarly drag and drop
D1_PRICELIST,D1_PROD_DIET_TYPES,D1_PROD_SUBTYPE,
D1_PRODUCT_TYPE,D1_SUPPLIERS.
Step 4 :
Drag and drop newly added 5 columns onto products
presentation table.
