Master Data Loading - 0EMPLOYEE

Hi Experts,

I'm trying to determine how to procede in regards of master data loading - I will have to determine if i need to create process chain and what will i have to include in this process chain.

From what is currently implemented (some loading for 0EMPLOYEE have already been done) i see that there is duplicates (e.g I have the same employee 3 times in =employee infoobject with different validity dates).

So my question is: how can I check if a certain object is overwrite or addition (if we have something like that for infoobject)?

If we have duplicates, the the best option would be the creation of a PC that fisrt deletres the content of the object and then load all the infopackages, correct?

Many thanks

Joana
