Date format conversion through OD

Hi Experts

My client has a requirement where QM inspector enters the value in a MIC (Date) which is further linked to Class characteristics (Initial_date). In this way, this value is getting updated in the batch classification (both are numeric format)

Another characteristic (Date format) is made i.e Actual_date and assigned to respective class.

Here is the requirement, Since the QA user enter the value as 21122013 and same is updated in Initial_date as 21122013 (on the basis of linkage between MIC and Class characteristics), Value in Actual_date should also get updated in final format i.e 21.12.2013.

Is it possible to achieve through OD assignment? If yes, what are required syntax to achieve this??

Thanks,

Gaurav
