Need asnwers - interview questions

Question

Hi Experts,
I am a novice candidate pursuing for SAP BW/BI opportunities and appearing for different interviews in SAP BW/BI. Following are some of the questions that I was fired by the interviewers. I appreciate your time and consideration for answering my queries.
1)How do you initialize the setup tables for filling the data of just past three years ?
And after full load from set up tables and executing the delta, later there is a requirement of adding more application tables in the datasource of LO cockpit.How should we go about without getting duplicate records in the source system and retaining the original delta
2) what are the general different transformations issues and methods to solve it?
3) How to handle DTP issues like if number of records were 1000 in DSO object and the Infocube received just 900, bad characters problem,etc
4) RDA background process flow?
5) How to have plan/actual comparisons?lets say Profitability analysis.
Plan infocubes contains which data with respect to actual infocube? Can you explain with example?
6) In business content activation,how to exclude the objects that have been already activated.
7)Does change run affect all aggregates or only aggregates containing that master data which is undergoing change run is affected?
8) Can somebody send me sample Functional requirements design documents/blueprints/detal design docs.
9) what are functional support issues in SAP BI implementations?
10) The fastest and best method to improve query performance?
If I am right, is it Cache settings?
11) I am also preparing for certification exam BI 7.0 which is on march 7th? I need some sample questions.
12) Need more information to prepare for SAP BI functional analyst and developer interviews.
Thanks
Mujtaba.
Lot of points will be given for urgent replies.

Answer 1

1)How do you initialize the setup tables for filling the data of just past three years ? And after intilization/full load from set up tables and performing the delta, later there is a requirement of adding more application tables in the datasource of LO cockpit.Here we still need delta load for the original records.
You can give the date  for the past 3 yrs and fill the setup table.
2) what are the general different transformations issues and methods to solve it?
Short dump while creating transformation
Inactive transformations
Error while copying transformations
Automatic transformation not possible etc
3) How to handle DTP issues like if number of records were 1000 in DSO object and the Infocube received just 900, bad characters problem,etc
You can do it with error handling.( Error DTP, you can maintain in Error DTP and schedule the load from Error DTP to Target).
You can do
4) RDA background process flow?
The RDA concept has been implemented in BI 7 . This is to get the real time data from the source system for a regular interval of one min or more than that .

5) How to have plan/actual comparisons?lets say Profitability analysis.
Plan infocubes contains which data with respect to actual infocube? Can you explain with example?
Actual data is loaded from R3 or any other source, Planned data is loaded from APo or entered manually...
U can switch between actual and planned mode and load data from source or enter the data in planned mode..
Example
Stock/sales can be predicted and entered in plan mode vs actual mode
6) In business content activation,how to exclude the objects that have been already activated.
Chk compare/copy check box...
7)Does change run affect all aggregates or only aggregates containing that master data which is undergoing change run is affected?
It will hit the aggregates for which master data changes has happened
8) Can somebody send me sample Functional requirements design documents/blueprints/detal design docs.

10) The fastest and best method to improve query performance?
Is I am right is it Cache settings?
Aggregates
Avoid nav attributes
Dont fetch line item dimensions unless needed
Avoid too many chars in the row
Avoid using RKF and CKF as it fetch data from database
Query Read mode(adjust with A, X and H)
11) I am also preparing for certification exam BI 7.0 which is on march 7th? I need some sample questions.
