Error FCEXEC in creating forecast

Question

I am trying to create forecast in AWM with foodmart database. There are 5 dimensions, dim_timeall, dim_customer, dim_product, dim_store and dim_promotion, with 1 cube cub_salesfor. I followed example in OLAP Application's Developer Guide 10.2. Dim_timeall includes all of history period and forecast period with day as base level.
First trial :
I made 2 measure with short decimal type and then I used them in fcexec :
FCEXEC handle TIME dimtimeall INTO forecast_sales SEASONAL forecast_sales_seasonal cub_salesfor
After I compile, there were error message :
ERROR: (ORA-33686) The time-series parameter to FCEXEC is not dimensioned by AW_20MAR!DIM_TIMEALL.
Second trial :
I made 2 measure with short decimal type and I selected DIM_TIMEALL, DIM_TIMEALL_HIERLIST, DIM_TIMEALL_LEVELLIST, DIM_TIMEALL_TIME_START_DIM and DIM_TIMEALL_TIME_START_DIM1 in tab Dimension, and of course with the same fcexec.
But, I got the same error message.
Somebody help me, please...

Check the following:
* forecast_sales is dimensioned by dim_timeall
* forecast_sales_seasonal is dimensioned the same as forecast_sales. It may have extra dimensions, but it must have all the dimensions of forecast_sales. If it has extra dimensions, the status of the extra dimensions must be limited to a single value.
* cube_salesfor is dimensioned the same as forecast sales. It may have extra dimensions, but it must have all the dimensions of forecast_sales. If it has extra dimensions, the status of the extra dimensions must be limited to a single value.
There is usually an SMSEASONAL parameter, but I don't know if it is required.
An example forecast program follows. It might be useful as a template.

" the forecast handle. Define the a variable if it does not already
