To answer this question, the user needs to know about the different types of structures used in SAP BW. Specifically, the user needs to know about the PSA (Persistent Staging Area) table and how it is structured.

Option A is incorrect. The PSA table does not have the exact same structure as the Transfer structure. The Transfer structure is used to map data fields from the source system to the PSA table, and it has a different structure than the PSA table.

Option B is incorrect. While the PSA table is similar to the transfer rules in that they both map data from source systems to the PSA table, they have different structures.

Option C is incorrect. The Communication structure is used to transfer data between different components of SAP BW. It is not used in the creation of the PSA table.

Option D is correct. The PSA table has the same structure as the Transfer structure, with four additional fields added at the beginning. These fields are used to store metadata about the data in the PSA table, such as the load date and the request ID.

Therefore, the correct answer is:

The Answer is: D

To solve this question, the user needs to have knowledge of the InfoCube-specific properties in SAP Business Warehouse.

The statement "If a characteristic value has been entered in InfoCube-specific properties of an InfoCube, only these values can be loaded to the cube for that characteristic" is True.

Explanation:

In SAP Business Warehouse, InfoCube-specific properties are used to define the behavior of an InfoCube. One of the properties that can be set is the "Fixed value" property for characteristics. If a fixed value is set for a characteristic in an InfoCube, only that value can be loaded into the InfoCube for that characteristic. Any other values for that characteristic will be rejected during the data loading process.

Therefore, the statement is true and option A is correct.

The Answer is: A

To understand the statements made about the OLAP CACHE, the user needs to know what OLAP CACHE is and how it works. OLAP CACHE is a technology that enables faster query processing by storing query results and navigation states in the application server memory. With that said, let's go through each statement and determine if it is true or false.

A. Query navigation states and query results are stored in the application server memory.

This statement is true. OLAP CACHE stores both query navigation states and query results in the application server memory, enabling faster query processing.

B. If the same query has been executed by another user the result sets can be used if the global cache is active.

This statement is also true. If the global cache is active, the result sets from a previously executed query can be used by another user who executes the same query, resulting in faster query processing times.

C. Reading query results from OLAP cache is faster than reading from the database.

This statement is also true. Because OLAP CACHE stores query results in the application server memory, reading those results is much faster than reading from the database, which requires I/O operations.

D. Changing the query will invalidate the OLAP cache for that query.

This statement is true. If a query is changed, the OLAP CACHE for that query will be invalidated because the query results and navigation state will no longer be valid for the new version of the query.

Therefore, the correct options are:

A. True B. True C. True D. True

The Answer is: D
