Starting with new SAP development environment SAP Cloud WebIDE has a few drawbacks. First of all network performance problems can dramatically effect your development. Besides your company might not allow you using Cloud WebIDE because of securtiy reasons. For that purposes i highly recommend you to use The Personal Edition of WebIDE. You can download it from https://tools.hana.ondemand.com/#sapui5 . It has trial and productive usage versions. Untill productive usage we are using the Trial one with almost any problem. The only problem was in setup configuration phase. After downloading the files and extract files under C:\SAPWebIDE you also need to configure your destinations under C:\SAPWebIDE\eclipse\config_master\service.destinations\destinations folder.
Code inspector provides a set of configuration which are customizable. You can either include or exclude any standard or custom check into your variant. By doing this you can prevent certaion types of checks in your ABAP programs. The only place to customize your variant is SCI. However there is a hidden customization where you can also set priority for the standard and custom checks. Go through the following steps to switch code inspector check priorities so that you could for example prevent a transport request to be released because it is consisted of an object with an error statused check.
I know the post header does not make enough sense. However this is an expalantion for the solution of a problem that i come across recently, and i believe it will be very useful for such cases.
As far as i have discovered new commands coming with ABAP 7.4 (COND,SWITCH), i realized that they have some superiority over the old predecessors considering code repetition. Lately i have started to make use of COND command very often. The reason for that is SWITCH has same usage with CASE but has less code. Likewise COND provides declaring free conditions and accordingly assign a field value therefore has less code than IF. Below i have written very simple sample code for you to easily compare each of these commands.
In consume REST oauth service from ABAP – get access token in order to call main webservice – part 1 post, i had tried to explain how a key required by REST services can be obtained. In this step i will make use of this generated key so that i can call my real service. Here all i have to do is creating the body part of my JSON data, the rest is again using right methods of cl_http_client. After consuming service the response from the server will be processed and siutable message will be returned.
I have heard many things about REST, oauth, JSON and all these things. Finally i have to meet these terms this week. There was a third party tool which is provding a REST service and i have to consume it with ABAP. Interestingly i learnt that there is not any Enterprise Service infrastructure in order to call REST services. Therefore i had to use HTTP service objects within ABAP program library. cl_http_client is the main class for REST services. Calling a REST service is consist of two parts. In this post i will focust on the first part. It is getting access token which is required to successfully make main webservice and this is the second poart of REST service.
When you want to pass data between different programs you make use of EXPORT/IMPORT FROM/TO MEMORY commands of ABAP. Unfortunately there is a limit for the size of data transferred with this command. I suppose it can be configured but for the SAP system i am working it is 2GB. Therefore when you want to pass an internal tables with many records there is a chance to exceed this limit and when it pass over the limit the program terminates with a EXPORT_TOO_MUCH_DATA exception and has a short text “Too much data for export”.
