CHANGEDOCUMENT_READ_HEADERS only returning "my" changes

Hi,

I have the following code in my program:

CALL FUNCTION 'CHANGEDOCUMENT_READ_HEADERS'

EXPORTING

date_of_change = p_stdate

objectclass = 'EINKBELEG'

date_until = sy-datum

TABLES

i_cdhdr = i_cdhdr.

According to the documentation, if the "username" parameter is blank, ALL changes should be returned, but this is only returning changes made be my username.

Am I doing something wrong...can anyone shed any light on what I should be doing differently?

Thank you for your help.

Andy
