We are reading time dependent master data (0COSTCENTER) into the data flow of transactional data.
Currently it is set to "current date".
If you create now a new costcenter starting from 01.01.2014, valid up to 31.12.9999, and load planning data also valid for the next year, then master data of the current date is loaded.
To prevent this and get the most recent master data you would have to flag the "End" button. Am I right?
