AFS Component ATP Check in the Purchase Order 
AFS Component ATP Check in the Purchase Order
Use
AFS has enabled the component ATP check in the stock transfer item of the purchase order for AFS materials. If the item is either not available or not fully available the system shows an AFS overview screen of the availability situation at SKU level.
AFS still displays the standard ATP overview for standard components.
Integration
In the standard system it is only possible to perform an ATP check for one schedule line but AFS has enabled component ATP multiple schedule lines to allow an ATP for SKUs. The system issues a report with one line per component and displays the required quantities (sum of all requirements for a component) and the total confirmed quantity. The requirements date is the latest date of all schedule lines.
The AFS lock logic differs from the standard for this function. In the standard the confirmed quantity is not updated until you save and in AFS it is necessary to update the confirmed quantity after each schedule line/SKU so that the second schedule line can not be assigned the same components at the first one has just received.
If a quantity is manually changed in the purchase order and ATP is not rerun for the components the system will have inconsistencies. The confirmed quantity will not have the current confirmed quantity unless you run ATP or run the report /AFS/MMPO_DELETE_VMENG.
The AFS component ATP check also differs from the standard as to which stock it checks for in the second Step. In the first step the ATP simply checks for available component stock for the subcontractor as in the standard but in the second step, AFS only checks for free available stock and not stock assigned to other subcontractors as in the standard system.
