BBP_DOC_CHANGE_BADI -> adding account assignment

Hi,

in the badi BBP_DOC_CHANGE_BADI I would to add by default an account assignment (table ET_ACC ) for every new items;

I would ask if it's possible, because debugging it the field GUID of current item is empty, so I don't know how to fill field P_GUID of ET_ACC

thanks!

Alberto
