You can quickly configure your SCD metadata on ODI datastores using this helper script here. Executing this script from the UI you can specify a driver file to quickly annotate your datastores with slowly changing metadata flags on the columns. To illustrate, let's use the dimension from an earlier posting here, the driver file below will configure all of the column metadata we need on the datastore in ODI.
We can have many datastores configured from one file and use * to set the same value for all columns (that's what I did for overwrite on change above). The script also allows the omission of the model and datastore so you can just specify the column name and the scd type (the add row change line above).
After executing the script the metadata tags defined in the input file are applied to the model in ODI;
Scripting is a great way to beat those boring tasks when you are building large systems where you realize you can work more efficiently. The groovy script invokes the setScdType method on the OdiColumn class here. A little groovy goes a long way.
