Sales Office for BP with role of ship-to party

hi experts,

There are some business partner whose role is Ship-To in database table CRMV_BP_FRG0140.

My question is why the table field "Sales Office" has value however I couldn't find the "Sales Org/Sales Office" in the Sales Area of that Ship-To BP.

PS: There exists another BP with role of Sold-To who has been maitained Sales Area Data,and this Sold-To BP has relationship in Partner Function with the above Ship-To BP.

--Does this explain my question? Please tell me more details.Thanks in advance!
