Working with Fields
Field concept
The concept of input / output is in programmatic terms generic term for:
• Fields (with a rectangular pattern in the screen image into your data
can enter and / or the R / 3 data outputs)
• Radio buttons
• Checkboxes
The definition of input / output is in the ABAP Dictionary (Data Dictionary)
made within the ABAP Workbench.
The ABAP Dictionary is a component of the ABAP Workbench and is the central management of all description and used in R / 3 data definitions. It is fully integrated into the ABAP Workbench. All other components of the ABAP Workbench can actively in the ABAP Dictionary to access definitions.
When defining an input / output must define a data element is that the data type for example numerically, alphabetically and includes the content importance of the input / output description. It refers to a so-called domain that also contains the data type and permissible Field data describing e.g. by providing information about the field length (number the possible characters) and the number of decimal places.
Radio buttons and checkboxes always have the data type of CHAR length 1 A marked radio button or a checkbox labeled complete the corresponding data element with the value of X, otherwise with SPACE.
The subdivision of the field definition in the data element and domain facilitates the translation of field names in other languages. In addition, any in system domain to be included in the definition of other fields used if any changes to a domain, the fields are referring to that angle change simultaneously and consistently.
The term "field" we use in the following for an input / output with rectangular template () in the screen. Since the term "field" in SAP Jargon is often used, we use it as a synonym "for" box. It highlights the facts that a user in make this field alphanumeric input via the keyboard or do.
They have already learned about the fields from the user perspective, eg in R/3- application image in the dialog box for password entry and the status window.
Fields are used to input data by the user and / or output of data by the R / 3.
Mandatory field, Optional field
SAP R / 3 checks your field entries in several respects. Example, if you enter in a field of numeric type a letter, it will be automatically entered incorrectly recognized.
A mandatory field is a field that is entered into the user data must.
Required fields are usually characterized by a hook symbol (see the box "users" ("user")) in R/3-Anmeldebild. The hook symbol appears only if this box is not clicked
have.
You can create a window with one or more required fields to be successful (without error) to leave if all mandatory fields with data have been filled. It may be the case that you are in one of several fields need to enter data, although in none of these fields, a hook symbol was deposited. For example, it is possible that in a window
either a statement in the field "day" or a statement "in the field week" is required.
An optional field is a field that is entered into the user data can. Some windows contain only optional fields, these windows you can successfully left without data entry.
Entering data into fields and navigation between fields
During the processing of most R / 3 transactions you have data in fields. Enter you have the opportunity to do so by using the mouse and to accomplish keyboard or only using the keyboard.
With the mouse you can click in a field (which you do data entry Select) and present in a field of alphanumeric text parts mark. When you click on a standard system in an empty field the cursor automatically jumps to the top of the field. Clicking the corresponding status field in the status bar, you can always switch between insert mode and overtype. Your data can either type using the keyboard or by copying from the clipboard. |
