Will Delta work in this scenario

[Former Member]

Hi All,

I had a scenario which I could explain you more clearly step by step.

1. We are refreshing data into Infocube A (for specific Document types) on daily basis from a DSO (Delta update).

2. Then on frequent basis such as once in a month, we are loading contents of Infocube A into Infocube B (Delta update). After that we are dropping the entire content of Infocube A. Then reloading the data again from Infocube B to A (Delta update) where some update routines are used in the transformations.

3. The next day as usual, daily delta refresh happens from DSO to Infocube A which was explained in step 1.

*Note:*

1. All the data loads to Infocube A are executed using DTPs (Delta updates from all sources like DSO and Infocube B).

2. Different souces and different DTPs are used to load data in Infocube A. Here, sources:- DSO and Infocube B.

*Question:* Will the delta mechanism efficiently work when we perform the daily delta refresh from DSO to Infocube A even after the step 2 is performed ?

Please clear my doubt. Also let me know if i could provide you any further information.

Hi ,

In your case to be begin with you are laoding delat from DSO to cube A

then cube A to cube B till here it is fine

now when you are dropping the contents of CUBE A..the init request which is related to (DSO to cube A) will be gone

that means you can't carry out any delta from DSO to Cube A.

Hi Swapna,

Thanks for the answer.

I still confused with this. What if we run the delta DTP from DSO to Infocube A after reloading the data from Infocube B to Infocube A. According to my knowledge, I think the delta from DSO to Infocube A works based on the Change Log table.

Here, will the delta mechanism compares the data in Infocube A which was loaded back from backup Infocube B with the data in the changelog and update the changed or new records into Infocube A from DSO.

What is the mechanism that is being carried out if we follow the above load process ?

Hi Ravi,

ur procedure looks fine......it should work fine and as swapna said about the INIT form DSO i dont think the INIT in DSO is going to effect after the step 2 in ur procedure.

Thanks,
