In transaction BP , from application bar select person. i.e person has to be created.
In that page in heading standard Address there is field called street. There is no search help displayed. But when we click F1 and on technical information.it shows table as ADDR2_DATA and field as street.
When we double click on Street it opens the above table and when we select Street and click Entry help/check tab button it shows that explicit search help CLSTRTNAME.
If search help is attached then why i am not able to see it on transaction BP.
