Creating the Pool Linkage
If you want to bill usage with an aggregate contract from a certain, valid point in time, or perform a recalculation with a single pool contract, link a single contract with a pool contract. You define the linkage in the single contract. The linkage is initially valid indefinitely, which means it has no defined end date.
The change process takes place at item level.
This change process is defined in Customizing under the technical name ASPL
.
Prerequisites
You have created a pool contract.
You have specified a valid linkage date; that is, the date lies within the contract duration of the service contract/pool contract.
The linkage date coincides with the start date of a service period.
The usage billing periods are synchronized with the service billing periods; that is, the end date of a usage billing period coincides with the end date of a service billing period.
The organizational data and currency are identical in both the contract item and the pool contract item.
You can run additional checks by using Business Add-In CRM_DOC_FLOW_CHECK (transaction SE18).
No active link to another pool contract exists within the proposed linkage period.
No billing document has been created yet for the proposed linkage period of the single contract.
You have neither prebilled the pool contract nor prebilled the pool period for the proposed linkage period of the pool contract.
Process
The following figure shows the process flow for creating the pool linkage:
