I'd suggest you consolidate it into a single fact table.  Personally I'd use a series of ApplyMap() 's, but others may prefer joins.

Create a series of Mapping Tables for Branch, City, Customer, Salesman etc. Then you can use Applymap to bring this data into your transactions table.

See this post for more details.Don't join - use Applymap instead

Applymap is the best approach as suggested by Colin,

you dont need to load higher level hierarchy in the same table .

Ex.

City:

LOAD CityID,

     City,

     CountryID

No need to load 'CountryID' on this table .

(

City:

LOAD CityID,

     City)


load all the table with two columns (IDfield and Name)

You can later load it in other applymap table and directly populate Country in Fact table using Applymap function.

Hi,

As suggested by all go with Applymap()

In case you have more then 1 description against any ID then ApplyMap() will not work here.

could you post some data as all your tables come from one file C:\QV\data.xlsx?

is much easier to answer with some data to work
