ERP is an acronym for Enterprise Resource Planning.

ERP software tracks the day to day transactions and processes within a company. ERP software tracks various business resources like cash, raw materials, production capacity, and sales.

Q6) Why we have only 16 Dimension tables in a cube. Is there any reason. Is it a limitation?

Ans: SAP BI Info Cube Can have a maximum 16 Dimension, Why because a Cube shape will have only 16 Dimensions and also Normal database table will have only 16 key fields. When we create the Info Cube system is going to create tables like F-table and  E-table So, we should follow that database concept Because Info Cube will Have only 16 Dimensions.

Q7) Why we are going for customization? Give me a scenario?


  • For Requirement as per company
  • Reporting As Per Module
  • Remove Complexity From End-User

Q8) Where do you store the master data in  BI 7.0?

Ans: Unlike the older version of BW which uses star schema, BI 7.0 uses the extended star schema. In this, master data is stored outside the cube. In the star schema, both master data and transaction data reside inside the cube bringing many problems: master data not reusable, computing of alphanumeric values, and analysis is limited. In BI 7.0 Master data is stored outside the cube which makes it reusable, and alphanumeric values can be computed and many more analyses are possible.

Q9) What are the common Transport errors in SAP BW?

Ans: NOT CORRECT USAGE. Reason: When we change the structure of any cube which has Business Warehouse Accelerator Indexes created for it. Change in structure could mean a change as simple as adding a navigational attribute. solution: Delete the Indexes (BWA Indexes)first then transport and then rebuild the indexes Info Object not available inactive version. Reason: We get this error when we try to transport the Info Object Catalogs without transporting the info objects. Solution: As a prerequisite first transport the info objects then transport info object catalogs. The navigational attribute does not exist Reason: If we mark an object in the cube as a navigational attribute and the navigational attribute does not exist as navigational in the target system. Solution: Transport the info object with navigational attribute and then re-import this transport.

Q10) What advantage of ic with aggregates?

Ans: if we create aggregates on info cube then query performance will be improved if our query accessing attributes data frequently. The sequence when we execute the query is: Query first goes into cache if it finds relevant data in the cache will fetch data otherwise it goes into BI ACCELERATOR(BIA) Aggregates Finally it goes into IC if the data is not available in the above 3 stages. If we maintain aggregates or BIA OLAP no needs to come up to IC. So time will be reduced. Query performance will be improved.

Q11) What is used in SDK for developing a form?

Ans: Screen painter is used for developing form in SAP Business One SDK. Screen painter is provided as an add-on by SAP and it can be used to designing and developing forms.

End If

In the above code, the click event of the save button is handled. When the user clicks on the save button, then first the above code will execute and then it will be handled by SAP Business One. Here I have set BubbleEvent=False.So the click event will terminate and SAP Business One will not handle the event.

  • txtDocEntry.DataBind.SetBound(True, "", "DocEntry")
  • In the above code,I have considered the textbox txtDocEntry.I want this textbox to accept numeric input only.So I have binded it with dt_LONG_NUMBER as shown above.

Q26) What are the limitations of the DI server?

Ans: Following are the limitations of DI server 

  1. Metadata operations not supported.

Q29) Where does DI server execute i.e. client or server?

Ans: DI server executes on the server.

Q30) For performing heavy-duty operations what is a suitable DI API or DI server?

Ans: For performing heavy-duty operation DI server is suitable. The DI Server implements a connection pooling mechanism to enhance the performance and scalability of the server.
