Totals Variants 
You can calculate various subtotals in the line item display. For these subtotals, you can use the totals variants defined, or select the fields and their sequence yourself on the line item display screen. The fields presented for this are already specified in the system. You can change these specifications.
Example
In the following figure, the line items are subtotaled using the totals variant "Document type, posting key". The figure shows the totals for each posting key and for document type DA.

For the totals variants, you define the fields and the sequence in which they are used for calculating the subtotals. The following figure shows the definition of the totals variant used for the display in the above figure. The totals variant determines the criteria according to which the subtotals are calculated.
Totals variants are already defined in the standard system. If you want to change these variants or define your own, you must
Enter a name for your variant in your logon language (see the following figure, 1 )
Specify the fields used for calculating the subtotals and their sequence (see the following figure, 2 ).

For each variant, you can specify a maximum of three fields for calculating subtotals. The possible fields are displayed when you maintain the totals variants.
In addition, you can specify which fields are offered in addition to the totals records for calculating subtotals . The fields are specified separately for each of the account types "customer", "vendor", and "G/L". This enables you to determine the fields you require per account type.
The following figure shows the fields that are available for calculating totals in the line item display.

The system already contains fields for the subtotals function. If you require other fields, include them for the account types you require. In addition, you can specify the sequence of the fields on the selection screen. You place the fields that you require most often at the top of the field list.
