Hi,
An access sequence is a search strategy that the system uses to find valid data for a particular condition type. It determines the sequence in which the system searches for data. The access sequence consists of one or more accesses. The sequence of the accesses establishes which condition records have priority over others. The accesses tell the system where to look first, second, and so on, until it finds a valid condition record. You specify an access sequence for each condition type for which you create condition records.
There are some condition types for which you do not create condition records (header discounts that you can only enter manually, for example). These condition types do not require an access sequence.
Regarding your second query:
All supplementary conditions that the system is to suggest for a certain condition type must be grouped together in a separate calculation schema (see below). This calculation schema must be stored for this condition type (main condition).
Supplementary conditions are time-dependent conditions that are usually maintained for a certain condition type (main condition). Supplementary conditions are stored with their associated main condition in one data record in a condition table (=condition record).
No access sequence (see below) is assigned to condition types for supplementary conditions because no separate condition record has to be found for them.
Example: Discounts/surcharges and freight costs are frequently maintained in relation to the gross price (PB00). They are therefore entered as supplementary conditions belonging to the gross price.
The supplementary conditions are grouped together in calculation schema RM0002. This schema is assigned to condition type PB00.
