I just deleted some of the fields of the Business Partner Window by logging in through System Administrator and now when I created fields again , and set their alignment , i need to enter the Search key Manually.
It doesn't fills automatically like before, If i just proceed with blank search key i get the following error:
-----------> MBPartner.saveNew: [POSave_31778910-6af9-4ff2-8736-0335ea702a4f] Not inserted - C_BPartner[12] -----------> GridTable.saveWarning: SaveErrorNotUnique - ORA-00001: unique constraint (E2DEVELOPMENT.C_BPARTNER_VALUE) violated
Any help would be appreciated!!!
I got the answer, the problem was due to deletion of all fields on tab and creating them again, the ad_sequence got corrupted. Once the ad_sequence was updated from backend Oracle the Business Partner started working fine again.
