Classical Interactive with Push Button

Interactive reports increase the visibility of user when the user interacts with the basic list to get detail secondary lists. The basic list contains the brief information whereas the detail list contains the detail information. As per the requirement the user interacts with the detailed list whenever it is needed. That is the reason why it increases the visibility. Instead of an extensive and detailed list the user can actively control data retrieval and display during the session through this interactive report. The user can interact with the report with having the cursor position and entering the command.

There are several events for Interactive report:
1.       At line selection (when user double clicks to a particular field value)
2.       At user command (when user selects a particular field value and then clicks a push button)
3.       Top of page during line selection (it displays different content at different secondary lists)

To interact by using a push button the R/3 system has an option which is menu painter. We can do this by using the PF-STATUS. With the help of that we can create our customized menu where we can set push button. After that we have to write functionality under the event at user command. The push button must have a function code and by using that we can write our custom function. The system field SY-UCOMM is used to set the different functions in different push buttons.

Here we have an example where we select Vendor account details based on the selection criteria by select options. The report will have a basic list which will display the vendor details from LFA1 table. Then by selecting a vendor account number if we click the push button Purchase Order then we shall go to the first secondary list. This list is coming from the EKKO table. After that if we select any purchase order and then click the PO item button then second secondary list will be coming. This list is coming from EKPO table.

In this point of view we have used HIDE statement. HIDE actually hides the field value into the system to reuse that at any time. With the help of this statement the system loads the field name, field content and line number in which the line exists. The line number is stored in SY-LINNO field. Field symbols cannot be specified in HIDE. This statement works independently. If we select the cursor to any blank field then also the HIDE will store that value.

Since this is a demo system there is data discrepancy at the database level. Hence Material and storage location is blank.
