Now, with DAC, I have a similar problem with ETL lineage analysis. For example if I want to know how a W_ table is populated I have to navigate in DAC selecting the Table then click on the tab "Target for Task" then right click on the task and then "GO" to the task, click on the source table and so on for a lot number of click. I think possible to realize a "report" on the DAC metadata with some input parameters (Table Name, Execution Plan name and so on) in order to obtain the ETL flow from source to target. Do you have any suggestion? Do you think this is possible with a few number of well designed SQL query? Thanks Fabrizio Hi Mark,

Some interesting changes from the DAC database schema that ships with Siebel Analytics 7.8.2. As the others have said this should help to highlight issues with the ETL runs - and management like nice graphs! Hi Mark,

Finally had a chance to implement this at Work.

Some interesting changes from the DAC database schema that ships with Siebel Analytics 7.8.2.

As the others have said this should help to highlight issues with the ETL runs – and management like nice graphs!

I had done something similar but not from DAC. I used Informatica table data loaded into a simple custom fact table in Analytics Warehouse and was modeled with Day and Time dimensions. ETls were run from Autosys back then. It was a good value add and provided IT team with information to prioritize tuning activities. I was thinking of starting to work on it in my current implementation and came across your post. Thanks for the RPD! You made it easy for me. You are doing an excellent job! Hi Mark,

I've just uploaded the RPD file to our website if you want to take a look; it's by no means tested or whatever, but I thought you might want to see how I put the joins together. http://www.rittmanmead.com/files/DAC%20Analysis.rpd regards Mark Hi Mike, Kimmo

I did try this and seems to be working quite well. Only problem I had was combining data from Calendar (S_ETL_DAY), Task Runs and Tasks (especially data from table W_ETL_GROUP, no problems with combining data from W_ETL_FOLDER or W_ETL_PHASE), but I didn't have time to look this in more detail. Anyway, this is a kind of functionality that really adds value to the whole solution. BR, Kimmo Nice example Mark!
