Classical Report of Multiple Tables

After creating a classic report for single table it's time to create a report which will contain multiple tables. Here we shall fetch various records from various tables and then collate them to reach required output.

We have created a report which contains multiple tables like MARA, MARC and MARD. The materials contain different Plant and Storage Location in MARC and MARD tables respectively. All those different plant and storage location will be displayed with material number in output here. 

Here the plant is a big item and the storage location is small item. One single plant contains different storage locations. Materials are stored inside one of these storage locations. Now different materials can be stored in the same storage location.

In the program we have prepared internal table it_mara from MARA table based on the Select Option material number range. If material number is entered then only the program will give an output.

After preparing valid information of it_mara the program selects data from MARC (plant) table into it_marc for all entries in it_mara. Here we have to check the it_mara table if it is not initial. If we don't give this checking then all records will be selected from MARC table and that would be wrong. Hence we can say that this table checking is one of a prerequisites of For All Entries.

Similarly after preparing the it_marc table we shall prepare the it_mard table from MARD (storage location) for all entries in it_marc. Similarly the table checking of it_marc must be there. 

Now we have material (it_mara), plant (it_marc) & storage location (it_mard) information. We have to collate all these information to display the required output. To do this we have prepared an internal table it_out with an work area wa_out. This internal table & work area contains the structure ty_out as per the report output requirement.

Now we are looping it_mara to fetch material & type into the output work area. Here MARA is a master table hence we have to loop this table. Now one material can be maintained for different storage locations under one plant or different plant. Hence to populate output table we have to loop into it_marc and it_mard table. Here we are looping it_marc and it_mard with WHERE clause because we are going to fetch all records of plant and storage location at one time. So where clause will help us to point out the particular material and also will increase the performance.

Finally at the output population we have used control break statement like AT FIRST, AT END OF, AT LAST. With the help of that we have synchronized the output in different lines.

Following is the coding of the classical report.

sorry sir, but there is a mistake. We can use nested loop but for be a good programmer we shouldn't use nested loop. we can use here read table.
