• Click the right mouse button and select New Batch Job or Job in real time.
• Change the name .

The name can contain alphanumeric characters and underscores ( _). It can not contain spaces.
The software opens a new workspace where you define the job

Create a WorkFlow

• In the project area , click the created job.
• Select the " Workflow " icon in the tool palette .
• Place the " workflow " in the job workspace

Create a DataFlow "DF_DIM_DATE"

• In the project area , click the created workflow.
• Select the data flow icon in the tool palette.
• Set the data flow in the workflow workspace.

Start creatingyourdata flow.
Double-clickthe icon of thedata Flow.
You cannowstart placingobjects in thedata flow diagram. Objects can besourcetypes, target and/or Transforms.

Definea data flow "DFDIM_TIME"

The data flowconsists of the followingcomponents:

• A "Date_Generation transform" component definedas the source.
• A transformation"Query" to generate the datafrom theclonnne"DI_GENERATED_DATE"
• An MSSQL SERVERtable thatreceivesthe generatedinformation.

Specify the componentsof the flow"DF_DIM_TIME"

• Openthe data flowentitled "DF_DIM_TIME"
• Select Inthe localobject library, click the "Transforms"
• The object "Date_Generation" is in "Data Integrator"
• Drag and dropthe icon "Date_Generation" in the workspaceof"dataflow" tab.
• Click the"query" availablein the paletteand place theright ofthe object "Date_Generation" icon
• Inthe local libraryof objectsinthe datastore"MSSQL_INSTANCE1", drag the table"TIME_DIM" and dropthesubjectto the right oftransformation"Query"  like  the following configuration:

Configure the component"DataGeneration"

Click the object"Date_Generation" in the workflowspaceto open thetransformationeditor

Enter the following informationin the DatetabGeneration

• Start date:2002.01.01
• End Date:20014.12.31
• Increment:Daily
  

Clickthe green arrowfound inthe toolbarto return tothe workspaceof"dataflow".

Configuring thetransformation"Query"

In the projectarea, clickon the icon "Query", you will see that we havea single column"DI_GENERATED_DATE" in "schemaIn" five pillarsconstituting theoutput flowand processingoptions.

• Map the"DI_GENERATED_DATE" column withthe target column"DATE NATIVE" draggingthe source objectinthe target object.
  For mappingyou can proceedas follows:
• Select"NATIVEDATE" column from"SchemaOut"
• Thendragthe object "DI_GENERATED_DATE" from "patterninput"and placeit inthe tab"Mapping" Use thetable belowto completethe mappingof the remainingcolumns

• Clickthe green arrow toreturn tothe workspace.
• Save andrun the job
• Checkthe proper integration ofdata into the table"TIME_DIM" MSQLSERVERtarget.
