Master data question ?

Hi all,

I have an infoobject (ZDCODE) with master data and 6 attributes have been added

When I looked into the table /BIC/MZDCODE or /BIC/PZDCODE the table has altogether 10 fields

6 attributes + one for infoobject <b>ZDCODE</b> + zxseg + OBJVERS + CHANGED.

My question is if I didn't select zxseg as an attribute of <b>ZDCODE</b>, how come I have it in the master table.

any ideas, please let me know.

thanks

Sabrina.
