Extraction, Process Chains, ASAP Methodology

LO Extraction

203. What is the specific advantage of LO extraction over LIS extraction?

a. The load performance of LO extraction is better than that of LIS. In LIS two tables are used for delta management that is cumbersome. In LO only one delta queue is used for delta management.

204. What is Logistic Cockpit (LC)?

a. It is a technique to extract logistics information and consists of a series of a standard extract structures delivered in the business content.

205. What is the significance of setup tables in LO extractions?

· It adds the Selection Criteria to the LO extraction.

206. What is Delta Management in LO?

a. It is a method used in delta update methods which are based on change log in LO.

207. Suppose we performed a LO extraction using v3 update. This update method has problems after replication. Can you change the alternative methods?

a. This is only the extraction mechanism for logistics other than LIS and SAP is not recommended LIS extraction

CO-PA

208. What is partitioning characteristic in CO-PA used for?

· For easier parallel search and load of data.

209. What is the advantage of BW reporting on CO-PA data compared with directly running the queries on CO-PA?

· BW has a better performance advantage over reporting in R/3. For a huge amount of data, the R/3 reporting tool is at a serious disadvantage because R/3 is modeled as an OLTP system and is good for transaction processing rather than analytical processing.

210. Can we extract hierarchies from R/3 for CO-PA?

· No, we cannot, there are no hierarchies in CO/PA.

211. Explain the field name for partitioning in CO-PA.

· The CO/PA partitioning is used to decrease package size (eg: company code)

212. What is t-code for CO-PA?

· KEB0

213. What is operating concern in CO-PA?

· An organizational structure that combines controlling areas together in the same way as controlling areas group companies together.

214. What is field partitioning in CO-PA?

· Internally allocates space in database. If needed table resides in one or few partitions, then only these partitions will be selected and examined by SQL statement, thereby significantly reducing I/O volume.

215. Is CO-PA delta capable?

· Yes, CO-PA is delta capable.

216. What is operating concern and partitioning in CO-PA.

· Operating concern is set of characteristics based on which we want to analyze the performance of company. Partitioning is dividing the data into different datasets depending on a certain characteristics. Partitioning enables parallel access of data.

217. What is the difference between value fields and key figures in CO-PA?

· Value fields comprises of data which CO-PA gets from various modules in R/3. Whereas key figures are derived from these value fields.

GENERIC EXTRACTIONS

218. What are the steps in Generic extraction?

· RSO2 à

o Select the DataSource type and create

o On create DataSource screen:

§ Choose an application Component to which the DataSource is to be assigned.

§ Enter the descriptive texts. You can choose these freely.

§ Choose Generic Delta.

f. Delete overlapping requests

220. What are the data target administration tasks?

a. Delete Index

b. Generate Index

c. Construct database statistics

d. Initial fill of new aggregates

e. Roll up of filled aggregates

f. Compression of InfoCube

g. Activate ODS

221. What are the parallel processes that could have locking problems?

a. Hierarchy attribute change run

b. Loading master data for same InfoObject

c. Rolling up for same InfoCube

d. Selecting deletion of InfoCube / ODS and parallel loading

e. Activation or deletion of ODS object when loading parallel

222. How would you convert an InfoPackage group into a process chain?

a. Double click on the InfoPackage group

b. Click on the “Process Chain Maintenance” button

c. Type in the name and description. Individual InfoPackages are inserted automatically

223. What is a process chain and how you use it?

a. A process chain is a sequence of processes that are scheduled to wait in the background for an event. Some of these processes trigger a separate event that can, in turn, start other processes.

b. In one of our scenario we wanted to upload wholesale price InfoObject which will have wholesale price for all the material. Then we wanted to load transaction data. While loading transaction data to populate wholesale price, there was a look up in the update rule on this InfoObject Master Data table. This dependency of first uploading Master Data and then uploading transaction data was done through the process chain.

224. What is a Meta Chain?

a. Process chains which are clubbed together are called a Meta Chain. Each sub chain is triggered only when the previous Process Chain is successful.

225. What is process chain? How many types are there? How many we use in real time scenario?

· Process Chains can define interdependent processes with tasks like data loading, InfoCube compression, index maintenance, Master Data & ODS activation in the best possible performance & data integrity. Process Chains exist in administrator work bench. Using these we can automate ETTL processes. They help to schedule all activities and monitor (T-Code: RSPC).

226. Process chains: How to schedule data daily?

ASAP

227. What are the project phases in ASAP?

a. Project Preparation: We do a conceptual review at this initial phase.

e. Go-Live and Support: To production and support

228. What is ASAP methodology

a. ASAP is a standard methodology for efficiently implementing and continually optimizing the SAP software. ASAP supports the implementation of the R/3 System and of mySAP.com Components, and can also be used for upgrade projects. It provides a wide range of tools that helps in all stages of implementation project - from project planning to the continual improvement of the SAP System. The two key tools in ASAP are: The Implementation Assistant, which contains the ASAP Roadmap, and provides a structured framework for your implementation, optimization or upgrade project. The Question & Answer database (Q&Adb), allows you to set your project scope and generate your Business Blueprint using the SAP Reference Structure as a basis.

BEx Reporting

232. What are Structures?

a. They are a combination of characteristics and Key figures (Basic Key Figures, Calculated Key Figures (CKF) and Restricted Key Figures(RKF))

233. What does the term CELL mean?

a. The term CELL in the function of Defining Exception Cells is the intersection of the two structure elements.

234. 4 Different types of Variables:

a. Text

b. Formula

c. Hierarchy

o Variable Hierarchy Node with a fixed Hierarchy

o Variable Hierarchy Node with a variable Hierarchy

235. 5 Variable processing types:

a. User Entry / Default Value

b. Replacement Path

c. Authorization

d. Customer Exit

e. SAP Exit

236. When we run the query at query run time the wrong data has come for one key figure, what might be the problem?

a. If the Key figure is Calculated Key Figures (CKF), check the formula. If it is a regular key figure, check the respective values in the InfoProvider. If the values are incorrect, need to check the update rules & transfer rules. If they are correct in the InfoProvider, then do check the source system table, maybe they are captured in correctly in the Source System level itself.

237. When we run query at run time it is not displaying one key figure values what could be the problem?

· Check if InfoProvider has values for the same. If yes, then check the formula incase of CKFs or check the selection parameters/filters etc in query.

238. Suppress the unit from displaying on the BEX Report

· Go into the query where your key figure is.

· Right click on key figures in the column section.

· Select New Formula

· Name the New Formula, Actual Qty

· In the function column expand Data Functions & select value w/o dimension.

· NODIM() will appear in the formula. Click on your key figure actual qty from the operand list.

· Hide your key figure in the query and display this new one (unit free)

239. I have a requirement where in, in the BEx Report I have to display the date when the report was run i.e. the Current date. Do I have to make use of VB code for that or is there a simple solution for that. Any Suggestions?

· You can use Variable (type: SAP exit) for the same i.e., 0DAT (current calendar day- which will be picked up from System date)

· I'm not sure if u have to do something in BW for that, but I have on my reports after they have been run, gone to the File Menu, then chosen Page Setup, then Header/Footer, click the Custom Footer button, then I'd select my date and time to appear on the Right section of the page at the bottom. I've also then saved the workbook as such and that date remained there.

· Have you tried using Text elements in the report? If you click on the "Layout" button, you can then select "Display text elements" and then "General". This puts in a number of elements into the report (workbook) The one you're looking for is a text element called "Last refreshed". It records the last time the report was refreshed (i.e. the last time it was run).

240. Assume that there is 5 years of data to be loaded as per the client requirement we need a key figure in the reporting. How to get historical data to that key figure? Is it possible to load only the current data instead of loading historical data for a key figure?

· When you load, just load it for 5 years. If you want to see just a current data in the Key Figure just create a Restricted Key Figure (RKF) with fiscal year (current) or posting period with your current value.

241. When to report from R/3 and when from BW?

· We can Report from R/3 for all operational needs that are based on the transaction data. The optimum use of BW is to analyze the data from tactical and strategic point of view.
