Structures can be nested.
Within each application component, there are several packages, which are an even finer logical subdivision. If an input field is typed with a structure field that uses a data element, the following semantic information is available: In this condition, columns from both yo tables are linked.

The user can then change the values in the input fields. For compatibility reasons, you can define data objects using the DATA statement, without having defined the type beforehand locally in the program using a TYPES statement.
You specify the way in which the parameters are to be passed in the interface definition: There is an input field on the selection screen. To avoid confusion, it is recommended that you use internal tables without header lines. Single Step and Field Contents In debugging mode, you can choose Single step to execute the program statement by statement.
Do the fields itnroduction to a structure with a globally defined type? Searching for Database Tables You have introduvtion options for searching for database tables: In this case, for the single record operations, the system identifies the row to be processed.
If the keys are identical, the numeric values are added. For this reason, you should define the subroutine first and then call it.
Event blocks are called by the ABAP runtime system. Using global data types has several advantages: If you want to change the contents of the internal table, you must first change the value of the components within the loop and then overwrite the internal table row using the MODIFY statement.
Make sure you comply with the customer namespace conventions. However, these are not required during this training course. Despite this fact, the database interface can use the primary index in this case for selecting the data records.
A unique key workbency required. Using Global Structures for Data Objects A structure normally serves the purpose of centrally providing a data type in which fields from different tables are compiled.
However, in more complex programs, we will require several different event blocks. Line type This is the source of the attributes of the individual columns. Proceed workbencj you did in the previous exercise. In addition, transaction codes provide several additional link options.

Transparent Tables and Views First the values for this line buffered in the HIDE area are inserted back into the corresponding global data objects. If you are using a default status, this happens automatically every time you choose an icon, the menu function Choose, or the function key F2. As a rule, structures are created in the ABAP Dictionary that contain fields of the same type for the different tables.
The database can then terminate the search as soon as it has found the appropriate record. The example above shows one way of doing this. Enter a short text.
Course Description for BC
Create the attributes of the new package. Result Source code excerpt: You will also learn the different transfer types of a main program to the interface of a subroutine: As well as the technical attributes, the type of an input or output field can provide further information; for example, you can use it to control the field or wokbench help.
Which table type you should use in each case depends on how that table’s entries are generally going to be accessed: You now have two options: Alternatively, you can execute the subroutine statement-by-statement using Single Step. Only then you will be able to make full use of the user-friendly maintenance functions and robust nature of your program.
The system opens the Screen Painter automatically. Working with Structures Exercise 6: When the subroutine is called, parameters are passed to it in strict sequence. User jntroduction BC The last step in development should extend the program to enable the user to change data in the database. Specifying the Next Screen Dynamically
