Release 9.0 : exceltoCI for AR

We need to configure ExcelToCI template for our use in loading into PS_GROUP_CONTROL, PS_PENDING_ITEM and PS_PENDING_DST. We will need to use the below fields:

BU (business unit)

Customer ID

Dept #

Customer Name

Invoice #

Invoice Date

Invoice Amount

Accounting Date will be 10/3/11 (date of acquisition)

Payments terms: All due now

Is it possible to set the template to accept the above fields as input only? Also, is there any documentation available for above requirement.
