what is the function of <b>access sequences</b>
An access sequence is a search strategy with the aid of which the SAP System searches for valid condition records of a certaincondition type.
For example, you can stipulate for a price that the SAP System first searches for a price for a specific plant, and then for a generally applicable price.
For condition types for which you wish to maintain conditions with their own validity period, you must assign an access sequence. With this, you define which fields the SAP System checks in searching for a valid condition record.
An access sequence has been assigned to condition type PB00 so that prices can be maintained in purchasing info records and contracts.
No access sequence has been assigned to condition type RC00 because it does not have a validity period of its own. In the standard system, it is always maintained simultaneously with the price and is valid for the period of the price.
If you define your own access sequences, the key should begin with the letter Z, as SAP keeps these name slots free in the standard system.
You should not change the access sequences that are included in the standard SAP system.
1. Check the extent to which you can use the condition types and access sequences that are included in the standard system.
2. Create new access sequences by copying and changing similar existing ones.
In doing so, enter an alphanumeric key, which can have a maximum of 4 characters, and a descriptive text.
3. Maintain the accesses for the access sequence by specifying the condition tables in the desired sequence. The sequence indicates the order of priority of the accesses.
You can display and choose the defined combinations of key fields using the "possible entries" facility.
