What are ODI Flexfields?
In ODI you can create user-defined fields on certain objects. You can think of these fields as additional attributes for certain objects. At design time you populate these attributes with values that are then used at runtime, e.g. by a Knowledge Module. There are various Flexfields defined out of the box for very specific requirements, e.g. there are Flexfields defined on the Datastore object for SAP and HIVE data integration tasks.
Where do you create them?
You create Flexfields in the Security module under the Objects accordion. You can’t create Flexfields for all of the objects. While you can create a Flexfield for an Interface you can’t create a Flexfield for an Interface Target Table.
Once you have created the Flexfield you can then populate it with values in Designer.
You have a requirement to log errors to an error table using a CKM. Based on the severity of the error you want to allow records through to your target table. DQ checks that result in minor errors are logged in the error table and go through to the target. Records with more sever issues only go to the error table and do not end up in the target table.
In a first step we need to define a Numeric type Flexfield on the Condition object. We name this field Passthrough
When you create your DQ Condition in Designer you can then set the value for the Flexfield. The value 1 will allow the record to go through to the target table even if there is a violation of the DQ check.
In a next step we need to write some code in our CKM to make use of the Flexfield and implement the above logic.
We store the value of the Flexfield in a variable passthrough and flag all of the records with the passthrough value.
<? passthrough="<%=odiRef.getFlexFieldValue("" + odiRef.getCK("ID") + "","2500","PASSTHROUGH_COND")%>".replaceAll("'","''''"); ?>
As you can see from the figure below, 2500 is the internal ID of object Condition in the ODI repository.
