Define Access Sequence

Define Access Sequence
To define and maintain access sequences, you need to follow a few simple steps.
Step 1) Go to SPRO > Materials management > Purchasing> Conditions> Define price determination process> Define access sequences.
As shown below , you will find a dialog structure of Access sequencesAccesses and Fields.
  1. Choose the Access sequence you want to maintain (PB01 gross price).
  2. Double click the Accesses folder in the dialog structure.
Step 2) In the next step you define access methods for the access sequence. You can see that several access methods are present for one sequence.
Every one of them is exclusive. It means that if a record is found in first access (Contract item), meaning that if the system finds a condition available from the Contract item, it will not search further, and that value will be used. If not, system will follow the other accesses in order to find appropriate entry.
You can also set a requirement for an access method to be used. For example, there is a requirement 35 assigned to access 10, which uses condition table 17 - Material Info Record (Plant-Specific).
A requirement for access number 10 is 35 - Plant info record. If there is no plant info record for the combination of the values in table 17, access 10 will not be used at all.
Step 3)
  1. Select the access you want to modify.
  2. Choose the lowest level folder in dialog structureFields.
Step 4)
  1. You can see we are located on the details screen for access sequence PB01, access 20 and table 18.
  2. The key fields of a condition table used in the condition access are showed here.
Condition table consists of condition fields which have certain attributes assigned to them. When the system tries to access a condition record it uses these attributes.
  • Special value source – this field contains a value to be used as default while accessing (e.g. using a fixed info record category for the access sequence)
  • Init – if this box is checked system will allow initial value for this field while accessing the condition table. If not system will not process the condition table lookup.
  • Atyp – processing type in access. You can specify if the field is relevant for condition access if it is part of a free or fixed key type. Default is left blank (fixed key type).
  • Priority – priority of a field (characteristic), it can be set from 01 to 99. Most of the time this field is left blank.
