Writeback issue - Admin tool question

Question

I'm trying to configure writeback per pg 90 of the BI Presentation Service Admin Guide. I am having an issue on the steps related to the Admin tool. I created a new table, set up the connection pool and made the table noncacheable.
Can someone explain in detail the steps I need to take to add this table in the logical and presentation layers? I dragged this table into my logical fact table and then to my presentation layer. No rpd warnings or errors, but am I missing a step? Do I need to create any physical/logical joins?
When I create my report in Answers, I get the following error.
Error Details

SQL Issued: SELECT Employee."Employee Name" saw_0, Employee."Employee Number" saw_1, Facts.Comment saw_2, "Employee Expense Facts"."Total Expense" saw_3 FROM "Employee Expenses" ORDER BY saw_0, saw_1, saw_2

Answer 1

I am able to view the results before adding the column I want for writeback.
I tried making the change you suggested.
1. already done
2. already done
3. changed to mention total level for employee dimension
Checked consistency and no warnings or errors returned.
When I try to access the report I now receive the following error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 14020] None of the fact tables are compatible with the query request Total Expense:[DAggr(Fact - Employee Expense.Total Expense by [ Dim - Employee.Employee Name, Dim - Employee.Employee ROW_ID, Dim - Employee.Employee Number, Fact - Employee Expense.Comment] )]. (HY000)
SQL Issued: SELECT Employee."Employee Name" saw_0, Employee."Employee Number" saw_1, "Employee Expense Facts"."Total Expense" saw_2, Facts.Comment saw_3 FROM "Employee Expenses" ORDER BY saw_0, saw_1, saw_3
I appreciate your help. I'm not familiar with adding an unrelated table/column into our model to use for writeback.
