Non-additive measure - Actual and Average

I am working on a project at a manufacturing client. The measure I'm having trouble with is LeadTime (the number of days from manufacturing schedule to completion). It is used in a calculation to determine over/under inventory levels.

I need it to use the actual LeadTime for the calc at the SKU level and the average LeadTime at all of the aggregate levels.

Thanks for the help,

Dave

Hello! I am not sure about what you mean with SKU level but if you have two dates in the fact table, ManufacturingScheduleDate and ManufacturingCompletionDate, you can make a named calculation in the data source view(Analysis Services 2005) or a calculation in the ETL-process with SSIS.

Use the TSQL function DATEDIFF() for that and the difference between the MScheduleDate and the MCompletionDate.

I am not sure about your problem with the averages and what you are doing averages of?

You should be able to solve this with the MDX AVG() function.

SKU is the lowest level of data...the individual product being manufactured and sold. The LeadTime does not need to be calculated it is already determined for each product.Here is a table that I hope helps:

LeadTime

Product

Actual

Average

1001

3

4

1002

4

4

1003

5

4

Sub-total Sum

12

Sub-total Avg

4

When I set the measure LeadTime to Sum the calculation that uses LeadTime is correct at the product level, but wrong at the aggregate level.If I set the measure to Average then the calc is wrong at the product and right at the aggregate level.

I need to show the cube data with LeadTime as actual at the product level and average at the aggregate level.

Hello! Can you also indicate the expected values in the table for Actual and Average Lead time?

From what I have seen with other clients is that you have a manufacturing order id for each production of a product.

It is not a part of your table but can it be a part of the problem?

Here is a little description of the table from my last post.Three product ID’s (1001, 1002, 1003) with actual LeadTime for each product in days (3, 4, 5 – respectively).

The LeadTime measure is used with other measures (On-hand, Daily demand, Safety stock, etc.) in an inventory over/under calculation.But, LeadTime is the only non-additive measure.Because of that the calculation is correct at the Product ID level (3, 4, 5), but wrong at the aggregate level (12).If I set the measure to Average LeadTime at the Product level is wrong (4, 4, 4), but the aggregate is correct (4).I’m looking for a solution that gives me the correct calculation at all levels

This project is only dealing with inventory levels.Orders are not a part of the calculation except as a part of the Daily Demand figure.
