Summary :
This SAP Note discusses the functionalities and differences between multi-level ATP and CTP in APO. It explains the scope of multi-level ATP checks, which do not consider lot sizes (minimum, maximum, or rounding quantities) nor allow for Product or Location Substitution across multiple OLTP systems. It highlights that multi-level ATP is incompatible with Characteristics Dependent Planning (CDP) and allocation-based capacity checking, lacking automated sequence planning. Advantages include adjustable check scopes, component-level planning, and visualization of missing components. Disadvantages involve restrictions on lot-sizing, planning integration, and block planning compatibility.
Key words :
planned orders/stock transfers previously checked, planned orders/stock transfers created, automatically assign planned orders, subsequent lot size heuristic, multi-level atp exists, multi-level atp checks, multi-level atp check, lot size heuristic aggregated, block planning requires functions, lot size heuristic
