As of Release 4.0A, you can specify that several release orders can be created simultaneously against a contract. To achieve this, set the shared lock indicator for the relevant contract document type in Customizing.
The contract itself cannot be changed during this time.
The exclusive contract lock serves to permit the checking of the target quantity or value of the contract to be carried out consistently. In the case of a shared lock, under unfavourable circumstances it may happen that two users release against the contract simultaneously, and whereas each individual release order may be below the target quantity, the two taken together exceed it. In such a case the system will not issue a message.
