The EIM_ type interface tables use the xxx_BU/xxx_BI column pairs to map organizations. For example, the CON_BU/CON_BI column in the EIM_CONTACT interface table is mapped to the BU_ID column in the S_CONTACT base table.
In order for organizations to be resolved properly, you need to populate the xxx_BU column with the organization name and leave the xxx_BI column empty. Do not populate the xxx_BU column with the organization ROW_ID. EIM looks up the ROW_ID for the organization in xxx_BU and puts it in the corresponding xxx_BI column.
