3658879 - Contract creation from PR exceeds requisition quantity – no system error in SAP S/4HANA Cloud

• When creating a contract from a Purchase Requisition (PR), the system allows the contract quantity to exceed the PR quantity.

• No error or warning message is raised during contract creation, even if the contract quantity is greater than the PR quantity.

• SAP S/4HANA Cloud Public Edition
• Contract (Public Cloud)

1. Create a Purchase Requisition with a specific quantity.

2. Start contract creation referencing that PR.

3. Enter a quantity in the contract that is greater than the PR quantity.

4. Save the contract.

5. Observe: the system accepts the contract without any error or warning message.

• Standard SAP behavior does not include an automatic quantity check between PR and Contract.

• Validation for this scenario is not enforced by default in the system.

• Custom logic is required to trigger an error or warning.

1. Implement the BAdI MM_PUR_S4_CTR_CHECK.

2. In the BAdI implementation, add logic to compare the PR quantity with the contract item quantity.

3. If the contract quantity is greater than the PR quantity:

   • Raise an error message (to block saving), or

   • Raise a warning message (to allow override, if the business process requires).
