Classical Interactive Report

Interactive program generally interacts with user on the output screen. Let us suppose we have an output for a particular program/report. Now if we want details description by double clicking on a particular field or clicking on a button then it will be called interaction with output. By doing this we can go to the detailed report or secondary output. When we are on the secondary output then we can back to our first out by clicking on Back button. We can generate 20 secondary list of output. Hence a total of 21 output screen (1 Primary + 20 Secondary) can be generated by Interactive program.

We have a requirement where we have to prepare a primary output containing Purchase Order, Company Code, Category, Type and Vendor with PO Info. The secondary list will be generated with PO Item, Material, Plant, Storage Location, Material Group, Quantity and Unit of measure. The secondary list will be generated if we double click on PO field in primary output.

We have mentioned the tables EKKO, EKPO and T161T. Now we have declared the structure types of internal tables of it_ekko, it_text, it_out1 and it_ekpo. Here it_out1 contains the combination of two internal tables it_ekko and it_text and it_ekpo is for the secondary output. For internal operation we have declared work area of every internal tables.

Next we have mentioned the event INITIALIZATION. Under this we are calling program name, user name and system date of the program. We have declared here selection screen begin with block b1 and under this we are mentioning obligatory select option.

Now under START-OF-SELECTION we are declaring all the operations for primary listing. We have made 4 subroutines. In get_ekko we select fields from EKKO into internal table it_ekko. Then in get_t161t we select fields from t161t into internal table it_text for all entries in it_ekko. After that we are preparing the primary output in the basic_output subroutine. Now we have made another subroutine for displaying the primary output and that is disp_basic.

Hence the primary list is prepared now and now we have to create the secondary list. To make the secondary list we are calling event AT LINE-SELECTION which raises functionality when user double clicks in any field. Now we are mentioning GET CURSOR for that field and for that value of the field. When these two are matches with Purchase Order (EBELN) field then we are calling two subroutines for secondary list. 

Subroutine get_ekpo Selects fields from EKPO into table it_ekpo for all entries in it_ekko. Then it prepares the secondary output display in the subroutine of ekpo_output.

We also have raised events TOP-OF-PAGE which shows the header list of primary output and TOP-OF-PAGE DURING LINE-SELECTION which shows the top list of secondary output. Here TOP-OF-PAGE DURING LINE-SELECTION is used only for interactive reports. That means when user double clicks on the field the TOP-OF-PAGE DURING LINE-SELECTION event triggers to make the secondary output header.
