Single date dimension while creating Aggregate tables

Question

hi Guys ,
I have single date dimension(D1-D) with key as date_id and granularity is day-level. I have fact table(F1-D) which gives daily transactions . Now i created three aggregate tables with F2-M(aggregated to monthly),F3-Q(Aggregated to quarterly),F4-Y(Aggregated to yearly). As I said.I have a single date dimension table with date-id as a key.I have other columns month,quarter,year in Date dimension.
My question is : Is this single dimension table is enough to create the joins and maintain the BMM layer .I have joined the date_id to all the facts in physical layer. In BMM Layer i have one fact and 4 logical table sources .Ii have created dimension hierarchy on Date dimension and created the logical levels as year ,quarter,month and daily level and also set their respective level keys . Now after doing these i have also set the logical levels to the 4 logical table sources in the fact table.
Here i am getting an error saying :
WARNINGS:
BUSINESS MODEL Financial Model:
[39059] Logical dimension table D04_DIM_DATE has a source D04_DIM_DATE at level D04_DIM_DATE Detail that joins to a higher level fact source F02_FACT_GL_DLY_TRAN_BAL.F03_FACT_GL_PERIOD_TRAN_BAL
Can anyone tell me why am i getting this error .

Answer 1

1) as you suggest, creating mini dimension tables for each level
3) using views with select distinct x,y,z to model 1) but without the need for phsical tables
I have thought of these scenarios .But it's just creating a multiple Date Dimension tables with there respective grains if we follow 1 and 3 steps you mentioned.
But i don't want to create aliases or views either on Datawarehouse or physical layer (Admin tool).Just with using a single Date Dimension table I need to comeup with a solution as mentioned by my Colleagues.
2) pushing all the calendar attributes into the aggreate table (eg your year aggregate has all the year fields, your month aggregate has all the year fields and all the month fields etc.). Then in BM&M use the aggregate table as a logical table source for the date logical table.
What do you mean by "pushing all the calendar attributes into the aggreate table".If possible can you eloborate a bit so i can try in this way to get this done .
One morething .Here What they were saying is .Join the Single Date Dimension to all the 4 fact tables in Physical layer . Then drag all the tables into the BMM layer and create a Dimensional hierarchies for the Date dimension with levels as Year -->Quarter--> Month--> day level. With the Fact tables: Single fact tables with multiple logical table sources .Then we need to set the levels on the respective logical table sources with the desired levels .Say monthly aggregate table--> Month, Quarter Aggregate table--> quarter level in the Contents TAB.
When i do this I am getting the Warning:
