Screens have been defined in the system for individual entry functions for business transactions. These screens can change due to various factors.
Features
The system can automatically suppress fields. This may depend on the entries you make on the initial screens of the function. For example, if you enter the currency key for your local currency in the document header, the system suppresses the fields for foreign currency amounts in the line items.
Each accounting clerk can suppress fields using Editing options. For example, you can specify that you only want to enter documents in local currency. This means that the currency and value date fields no longer appear on the selection screen for the function. On the screens for the line items, the fields for foreign currency amounts are suppressed. All specifications made by accounting clerks for the editing options can be stored in the user master. For more information about using editing options and specifying default values in user master records, see the General Ledger Accounting, Accounts Receivable, and Accounts Payable documentation.
Data in the account master record
also affects screens. If a G/L account is set up as not tax-relevant, then the Tax code field is not displayed on the screen for document entry. The sections on master records explain which master record entries affect document entry screens.
Screen variants
that you specify for each company code require specific screens for some functions. For a company code in Italy for example, choose country variant 2. When entering vendor line items to this company code, the system displays a screen with fields for withholding tax. The screens for country variant 1 do not contain these fields. The different screen variants are explained in each of the subject-specific sections.
The field status, which is defined for G/L account master records and posting keys, can be used to modify screens in the system. You can determine what data is relevant in line items based on the posting key (business transaction), and account. To do this, specify which fields are not required in G/L account master records and posting keys. You also specify whether an entry is mandatory for fields that are displayed. See also:
