Yes, you can. You can use the available sorter property available on the List. It lets you specify all the required details. For e.g. −I have specified the employee collection to be sorted on the basis of the name of the employee and specified that the sorting should be in descending manner. It should also consider grouping while sorting the data.

The answer to your question is ‘NO’. It is not possible to map your complex JSON object (object of objects) to a list as it does not make sense.If you want you can have a model or a JSONModel which replicates your object and then you can map it otherwise as you said, you can try to use array if it suits your requirement.

It’s a straight forward way to do the same.You have to go to the transaction RZ11 for the parameter, if the dynamic field checkbox is checked it means that the parameter is a dynamic parameter otherwise it is not a dynamic parameter meaning it is a static parameter.

You need to use the function RSAQ_REMOTE_QUERY_CALL_CATALOG for fetching the list of SQVI queries for a user.

Your question seems to be uncertain. SAP stores data in database and SAP database structure is not conventional and quite complex.  You need to code separately on top of SAP to support export data to outside world and you are free to choose format of your choice.Identify the user specific SQVI queries in ABAP/BAPI. With use of QucikViewer (SQVI), it is a tool for generating reports. SAP Query offers the user a whole range of options for defining reports.Transaction Code: SQVI (Quick Viewer)You can check out this link to know more how to generate report:Create Report by usingsqviRead More

I think there can be a better option to do this. What you can try is fetch only the fields of the table which match the fields present in the table. Do not fetch all the fields of the table but the selected fields.// Here Table refers to the JCo.Table for (int j = 0; j < Table.getNumRows(); j++) {    Table.setRow(j);    Iterator iter = displayField.iterator();    // fetch columns present in the current record    while(iter.hasNext()){       String column = (String) iter.next();       String value = Table.getString(column);       // perform your logic here    } }

There are two operation LT (Less than) and GT (Greater Than) which you can use to perform basic comparisons between two variables.You can frame the logic as per your requirement whether you have a set of variables or a table. If it involves set of variables then you need to do manual comparisons.

There is nothing like standard but you need to specify all required details for a successful connection.XXXX-  H/IP Address/S/Port NumberHere H stands for Host, IP Address is the IP Address, S stands for Port Number

You can indeed achieve it. You just follow the below steps:Step 1 − Define the input parametersDATA:   table_name  TYPE string VALUE  ‘TABLE’, column_name TYPE string VALUE  'COLBNAME', name_value  TYPE string VALUE  'COLVALUE'Step 2 − Create a table type to hold the output results.DATA:   results TYPE REF TO data, TableType TYPE string FIELD-SYMBOLS TYPE STANDARD TABLEStep3 − Create a dynamic query to fill the table 

Basics things first, even if you are using a trial version but you still need to provide the license information and a developer key.Instead of using a DDIC user, you can try using a BCUSER for your requirement as it is a part of the trial version.You can try to include the SAP_ALL profile for your designated user.SAP_ALL get’s generated automatically whenever you transport authorization objects.You can generate SAP_ALL using report RSUSR406 or transaction SU21. This generates SAP_ALL only in the client where this report is executed. You can generate SAP_ALL using report AGR_REGENERATE_SAP_ALL. This report generates SAP_ALL in all ... Read More
