Creating New EIM Table Mappings to Existing Base Tables

You can create new EIM table mappings from an EIM table into a base table if either of the following conditions is true:

• Mappings already exist from the EIM table to the base table.
• The base table is an extension table and mappings already exist from the EIM table to the corresponding base table.

For example, you could create a new column in EIM_ACCNT_DTL and map this either to a new extension column in S_ORG_EXT or to an existing column in the extension table S_ORG_EXT_X. These mappings are defined using Siebel Tools.

If you create an extension column to a base table, then run the EIM Table Mapping Wizard, the Wizard creates the following mappings:

• The mapping for the newly added extension column
• The mappings for all unmapped columns in the base table, including unmapped Siebel base columns

In general, manually creating mappings to an existing Siebel base column in Siebel Tools is not supported. Please contact Expert Services for further assistance.
