Если нужно на экране входа в систему (где мы вводим логин, пароль, мандант, язык) написать какой-нибудь сообщение (например, какой мандант что означает), то нужно в транзакции SE61 создать текст ZLOGIN_SCREEN_INFO для класса «Общий текст». Там пишите что хотите.

Если что, то нота 205487.

Summary
Symptom

You want to display a customer-specific text on the SAPGui logon screen.
Other terms

SAPMSYST, screen 0020, logon, login, signon, sign on screen, logon screen
Reason and Prerequisites

Before Release 4.6 the logon screen, program SAPMSYST screen 0020, was modified for this. As of Release 4.6, modification is no longer necessary.
Solution

As of Release 4.6 it is possible to display customer-specific texts on the SAPGui logon screen. See 4.6A release note BC_46A_LOGIN_INFO.

Go to Transaction SE61and select the document class ‘General Text’ (selection using F4 help), and create a text with the name ZLOGIN_SCREEN_INFO in the system language determined with the profile parameter zcsa/system_language.

If the text does not exist in the system language, no output is made.

Note that there is space on the logon screen for 16 lines for every 45 fixed-font characters or for approximately 60 proportional font characters.

Title lines (can be recognized by format keys starting with a ‘U’) are highlighted in the display.

You may also output icons at the beginning of lines by using an icon code (for example, @1D@ for the STOP icon). You can get a list of icon codes from Report RSTXICON. Pay attention to the codes with two ‘@’ symbols displayed by the report. You cannot include text symbols. The function ‘include character’ cannot be used.

Creating/changing this text requires a changeable system. Therefore, for production systems, SAP recommends maintaining the text in the upstream system and then transporting it. To do this, select a transportable (customer) development class when you create the text and save the active version prior to the export.
The transport is done via the transport object R3TR DOCT ZLOGIN_SCREEN_INFO

The text can be changed in the original system only (see TADIR entry R3TR DOCT ZLOGIN_SCREEN_INFO). When making a change in a non-original system, a modified text would be generated which cannot be represented sensefully on the initial screen.

Caution — changed functions as of Release 6.40

Except for the above-mentioned formatting possibilities for:

* headings (‘U’) and

* icons at the beginning of a line

no further formatting is available that was was previously possible using SAPScript.
Warning

If you modify screen SAPMSYST 0020 (in older releases), then note that you may only insert text elements.
Changes to the flow logic, for example, by inserting subscreen, force a change in program SAPMSYST.
SAP strongly recommends not changing the system program SAPMSYST because by doing so, serious problems may arise (for example, the dialog logon is generally no longer possible!)
