Static methods do not use any instance variables of any object of the class they are defined in. Static methods take all the data from parameters and compute something from those parameters, with no reference to variables. We can inherit static methods in Java. Example In the example we are creating a class named Demo and, declared a static method named display(). We created another class Sample, extended the Demo class and tried to access the display() method using the sub ... Read More
It would be good to separate the HR from other modules as not only the load and usage is high on HRmodule but the business and security requirements differ for HR module as well.In such scenarios, other module can be customized in terms of security and configured as per theirneeds. Also separating the Central instance and database to different machine is a very commonapproach but can be avoided too by configuring the Central instance to adjust the load.

SAP provides a complete development environment. The same environment is used to develop the standard offerings so we can create our own custom ... Read More
In JCo3.0, Java client JCO.Client is replaced by JCoDestinations. You can connect to SAP system via Inbound RFC Communication (Java calls ABAP) or via Outbound RFC Communication (ABAP calls Java).For inbound RFC communication, you need to use JCoDestination for executing a remote function module at ABAP side. To use inbound RFCs, you have to use “JCoDestination” which executes a Function module remotely at ABAP side and while using outbound RFCs, you have to configure a JCoServer at the SAP gateway that is responsible to receive incoming requests from ABAP side and process remote function module at Java side.To know more ...

Let’s talk the standard way - It would be a great option to opt for creating a REST based ODATA services. You can expose the SAP functionalities mainly BAPI or any RFC as a service with SAP gateway. SAP gateway lets applications to exchange data across a variety of technologies and applications.In case the requirements are not extensive and can be catered by existing API’s exposed by SAP, then you can just enable the required services for usage. These APIs will require good hands-on knowledge of SAP Services.You can build an SAP source data plugin using JAVA and JAVA SAP ... Read More
You can check if there are any short dumps in SAP system using T-Code: ST22. When there are short dumps, it leaves ABAP Processor in an invalid state. This results in a failed call with an unspecified error message.
You can write an ABAP program for exporting the data from SAP and then use a remote function call which can be invoked my macro to fetch the data. Also, you can go for creating the file itself if that fits the requirement.You can also opt for SAP GUI Scripting as an alternative. The scripting framework allows you to automate the interface for Windows and Java. It can let you perform a lot of activities.Scripting API provides you with the good number of scriptable objects which wraps the SAP GUI objects. You can use these objects from macros. SAP GUI ...

You can make use of field - “wa_selrow” to define which column was clicked. Also, change the grid from row selection mode to cell selection mode.wa_selrow contains which field it is calling the transaction regardless or the field you clicked on so based on the content of wa_selrow, you can control the call to the transaction.You can also turn on the debugger and double click on the field to check what value is getting passed into wa_selfield.
Standard distribution of Python contains collections module. It has definitions of high performance container data types. OrderedDict is a sub class of dictionary which remembers the order of entries added in dictionary object. When iterating over an ordered dictionary, the items are returned in the order their keys were first added. >>> from collections import OrderedDict >>> D = {5:'fff', 3:'ttt', 1:'ooo', 4:'bbb', 2:'ddd'} >>> OrderedDict(D.items()) OrderedDict([(5, 'fff'), (3, 'ttt'), (1, 'ooo'), (4, 'bbb'), (2, 'ddd')]) We also need to use sorted() function that sorts elements in an iterable in a specified order. The function takes a function ... Read More
No, there is no other possibility of doing it until you code everything on your own. It seems to be an issue during de-serialization.Most probably it is relevant to the parameters that you are sending in the response.You can try and enable tracing to detect further and check out where it is going wrong.
