Screen Layout, Maintenance Level, Tab Layout for Master Data
The asset master record in the FI-AA component has a large number of fields in order to meet the needs of its many functions. To make master data maintenance nonetheless as simple and efficient as possible, the following Customizing functions enable you to design the asset master record to best suit your needs.
Screen Layout Control
You specify the field attributes in the asset master record, and the maintenance level of the fields, using screen layout control. You can define as many types of screen layout control as you need, and enter them in the asset classes (Customizing Master Data). There is screen layout control for
In each screen layout control, you can make specifications for the individual field groups. The corresponding maintenance fields are assigned to every field group.
Screen layout control® Field groups ® Individual fields
The field groups and their respective fields are defined in system tables. When you define the screen layout, the system proposes all existing field groups, and you maintain each one individually. You define specifications for the screen layout and for the maintenance level of the field groups, and you specify whether the field contents can be copied as a reference.
SAP supplies several predefined screen layout controls. In regard to depreciation terms (areas), the system offers the following depreciation procedures:
Using the screen layout, you control whether the fields of the field group are required fields, optional fields, display fields, or whether they should be suppressed completely (that is, not appear at all in the screen). For required fields, an entry is always mandatory in master data maintenance. You can choose whether to make entries in optional fields. You can only define field groups as display fields if the system determines the values in these fields (for example, insurance value). If you suppress all field groups of a screen, the screen is not displayed during master data maintenance.
By using the screen layout to control fields, you guarantee that the necessary fields are processed for each asset class. Each field group can have only one value in the screen layout.
Only fields that are blank or 0 can be suppressed using the screen layout control. Fields that are not blank or 0 are always displayed, regardless of the setting of the screen layout control. These non-initial fields may appear if:
In order to suppress these fields, you first have to define them as being changeable, and then delete their contents.
For each field group of the asset master record, you can specify one maintenance level. The maintenance level determines the asset classification level at which a field group can be maintained.
The maintenance levels in the system are:
You assign one of these maintenance levels to a field group, with the following results:
If you specify the asset class as the only maintenance level for a field group, you cannot maintain the fields on main or sub-number level. Instead these fields are for display only at those levels. The values for these fields are copied from the asset class to the main number and sub-number. Later changes to these field values in the asset class are not reflected in existing master records (main number and sun-number), but apply only to newly created assets.
If you specify the main number as maintenance level for a field group, you can only maintain these fields when creating or changing the main number. The values of these fields are automatically copied to sub-numbers created later, and can no longer be changed there.
If you specify the sub-number as maintenance level, you can maintain the field group on the main and sub-number level.
If you specify the maintenance level as main and sub-number, the field group from the main number is proposed as a default value during maintenance of the sub-numbers, but can still be changed.
Copying Using a Reference (When Creating Master Records)
You can create an asset using another asset as a reference. You use the screen layout to control whether certain field groups in the target asset can be completed with values from the source reference asset. You should not complete all fields by copying from the reference asset. It makes sense to maintain some of these fields separately for each asset, since they apply only to one asset (for example, the base insurable value and other value fields containing insurance data).
You cannot define a maintenance level for fields which are suppressed by means of the screen layout.
Due to the large number of fields, the asset master record is split up onto different screens and tab pages using tab layout functions. In Customizing (Master Data), you can specify how many tabs you want to have (up to a maximum of 8) and which field groups you want to be displayed on the given tab pages. You can make these specifications dependent on the asset class. If necessary, you can define exceptions within an asset class that are dependent on the chart of depreciation.
