End routine for a hierarchy data load in BW 7.3

Hi,

I am loading 0ORGUNIT_HR01_HIER data source through Transformation. I want to manipulate the To date of the delimited org units. For that I want to write the code in the end routine. I have written start and end routines for master data attributes and transactional data but not for hierarchies. If anyone has any suggestion or sample code that would be greatly appreciated.

Thanks,

Sankar
