SAP Business One Interview Questions

Q. Which are the dll’s used in SAP Business One SDK ?

Interop.SAPbouiCOM.dll and Interop.SAPbobsCOM.dll are the two dll’s used in SAP Business One SDK. Interop.SAPbouiCOM.dll is used for accessing the user controls that are displayed over the form.Different controls such as label,combobox,matrix etc. can be accessed using Interop.SAPbouiCOM.dll. Interop.SAPbobsCOM.dll is used for accessing objects that are used in SAP.For eg,item object can be accesed as, Dim objItem As SAPbobsCOM.Items


Q. What will happen if we remove EventFilters ?

If we remove EventFilters,then the all the events will fire.While programming in SDK,the unneccessary events should be neglected since it will decline the performance of the application.When EventFilter is applied to the SAPbouiCOM.Application object,then the events will fire as per the requirement of the user and thus enhancing the performance of the application.


Q. What is used in SDK for developing a form ?

Screen painter is used for developing form in SAP Business One SDK.Screen painter is provided as add-on by SAP and it can be used to designing and developing forms.The files created by screen painter has srf extension and these files should be renamed to xml for deploying then in SAP Business One.


Q. Which tool is provided by SAP for keeping the track of events ?

SAP Business One Event Logger is a tool provided by SAP for keeping the track of events.Both SAP Business One and event logger should be executed simultaneously.Event logger will give you detailed list of events that fired while operating SAP.Event logger is very useful tool while devleloping add-ons in SDK.Coding can be done as per the events that are shown in event logger.For devleoping robust applications in SAP Business One SDK,event logger is useful tool since entire programming in SAP Business One SDK is event driven.


Q. Is it possible to alter the standard behaviour of SAP Business One using SDK ?

The standard behaviour or the convensional flow of SAP Business One can not be altered using SDK.Some or other error will occur.So it is advisable not to disturb the convensional flow of SAP Business One using SDK.

objRS = objCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)

objRS.DoQuery(“SELECT * FROM OITM”)

The following are the uses of company object in SAP Business One –

  1. Access Data in an SAP Business One database.
  1. Connect to and disconnect to customer database.
  1. Start and end global transactions.
  1. Work with XML data.

Q. What are the different types of DataSources ?

The following are the different types of DataSources –

  1. DataTables
  1. DBDataSources
  1. UserDataSources

Q. Can we load the datatable directly using sql query ?

Yes,datatable can be loaded directly using sql query as follows –

Dim objDT as SAPbouiCOM.DataTable Dim strQuery as String strQuery=”SELECT * FROM OITM” objDT.ExecuteQuery(strQuery)


Q. What are the functions of Data Interface API (DI API) ?

Following are the functions of Data Interface API (DI API) –

  • DI API provides objects and methods i.e. add,update,Remove ,for performing various data level operations.This can be done without installing SAP Business One client.
  • DI API provides access to business objects i.e. master data and transactional data.
  • DI API can be used in COM capable development tools (e.g. Microsoft Visual Studio).Dll SAPbobsCOM.dll is provided by SAP just by adding the reference of this dll,you can perform data level operations.

Q. What are the different objects in DI API ?

Following are the different objects in DI API –

1.Business Objects

2.Infrastructure Objects

3.Special Objects


Q. What are the different types of transactions supported by DI API ?

Following are the different types of transactions supported by DI API –

1.Single Transaction

2.Global Transaction


Q. What is BubbleEvent ?

BubbleEvent specifies whether the event will be processed by SAP Business One or not.If BubbleEvent=True ,then SAP Business One will process the event else the execution will terminate.For eg,

If pVal.EventType = BoEventTypes.et_CLICK And pVal.Action_Success = True And pVal.FormUID = “F_32” And pVal.ItemUID = “btnSave” Then

BubbleEvent=False

End If

In the above code,click event of save button is handeled.When the user clicks on the save button,then first the above code will execute and then it will be handeled 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.


Q. What is DBDataSource ?

DBDataSource is used for storing data from database.DBDataSource is linked to database table and it represents tabular data.DBDataSource is used by all system forms.You can get DBDataSource as follows – Here I have assumed that I have opened the form of Sales Order and I want to get the database details of the sales order.The table name is ORDR. Dim objDS As SAPbouiCOM.DBDataSource

objDS = SBO_Application.Forms.ActiveForm.DataSources.DBDataSources.Item(“ORDR”)


Q. How to bind a textbox with datasource ?

Textbox can be binded to datasource as follow –

Dim objForm As SAPbouiCOM.Form

Dim txtDocEntry As SAPbouiCOM.EditText

objForm = SBO_Application.Forms.ActiveForm

objForm.DataSources.UserDataSources.Add(“DocEntry”, SAPbouiCOM.BoDataType.dt_LONG_NUMBER)

txtDocEntry = objForm.Items.Item(“txtDocEntry”).Specific

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.


Q. What are the limitations of DI server ?

Following are the limitations of DI server –

  1. Meta data operations not supported.
  1. Different support for transaction handling than plain DI API

Q. What are the different parts of DI API ?

Following are the different parts of DI API –

  1. COM Interface – The COM Interface provides the interface to the add-on application.
  1. DI Core – The DI Core, which is the main component of the DI API, performs all the data logic operations.
  1. Data manager – The Data Manager stores temporary object data, converts object data to internal data formats, retrieves data from the database, and controls the database transactions.
  1. Schema Generator – The Schema Generator creates XML schemas based on object interface descriptions. The schema generator also creates object validation lists.

Q. Where does DI server executes i.e. client or server ?

DI server executes on the server.


Q. For performing heavy duty operations what is suitable DI API or DI server ?

For performing heavy duty operation DI server is suitable.The DI Server implements a connection pooling mechanism to enhance performance and scalability of the server.As DI Server is a SOAP-based interface it does not limit the client to a COM interface, but allows a wide range of possible client technologies.


Q. What is the value returned when any method of an DI API object executes successfully ?

0 is returned when any method of an DI API object executes successfully.
