Hi Tea,
When i created Business Partner using transaction code BP, i am getting all the fields grey out. I believe something is missing in cross application componets - SAP Business Partner. I already addressed this issue in GTS forum, where in i got some help but it didn't solve my problem. The below link
will give you detail idea of your problem. Can any body in this forum who have got vast experience in master data can provide me some inputs
