This enables availability control at multiple levels and at various sites, considering the production capacity, substitution strategies, purchasing, transportation and any specific rules adjusted to your context.

GATP in APO supports online searches to decide whether requested products are available at particular times in amounts that fulfill customer demand. GATP processes are run via SAP live Cache, which processes large volumes of data and enables data sharing across several applications. GATP convenes the request of providing availability information across a global industry. The concept of GATP used in Sales and Distribution (SAP SD) module in SAP R/3 provides check capabilities that deliver results for basic business scenarios.

SAP APO GATP Basic Methods

·         Product Check

Product Check creates positive outcomes if the so-called ATP quantity for a product is available on the requested delivery date. If it is not available, a new postponed delivery date is suggested. The ATP quantity referenced throughout the product check depends on classifications defined in product check.

·         Product Allocation

Utilizing the information in the Demand planning, product allocation lets you know your accessibility to guarantee when sales orders compete for quantities in a restrained supply chain. New products, production downtimes, and other factors lead to varying requirements, which can affect product supply. For these situations, product allocation provides a tool to ensure a better distribution of the total amount when a company cannot pass the full available quantity to a client.

·         Check Against Forecast

The third basic method is check against forecast. It gives a check method that is particularly critical in make to order conditions, where inventory is not available to confirm the quantity requested by the clients. For this situation, the quantity verification is completed against the forecast.

·         Combination of all Basic Methods

Combination of all basic methods to spread its products proportionately in the market, the organization needs to perform product allocation initially, and after that availability check on its products. The check sequence of either method is done via the check instruction configuration. The product allocation first decides the resulting confirmed quantity, which is checked against the relevant ATP quantity from the product availability check.

·         Capable-to-Promise (CTP)

Capable to Promise (CTP) technology taps into SAP APO Production Planning and Detailed Scheduling (PP/DS) functionality. CTP triggers an online ATP check when a sales order is created. If the supply cannot cover the new demand, the PP/DS functionality is called on as a part of the ATP check. Production can be directly triggered through a CTP Check if the inventory is not available to satisfy an incoming demand. Production is either triggered for the full requirement quantity or partial requirement quantity depending on the available inventory.

·         Multilevel ATP

The basic idea of the multilevel ATP is to confirm a customer request if the components for the product are available in time. Basically, multilevel ATP explodes a Bill of Material (BOM) for the assembled product, and then checks the availability of each item at the component level. A multilevel ATP check determines the availability of each component required by the finished good.

SAP APO GATP Extended Methods

·         Rules-Based ATP

An ordinary ATP check is restricted to the requested location product and checks only the according time series. Using rules-based ATP it is possible to substitute both the location and the product. In branched supply chain networks, rules-based ATP allows companies to take full advantage of multiple shipping assets to ship goods from alternative sites to customers. In addition, it permits certain products to be substituted as required to successfully satisfy customer demands. RBA is beneficial for Distributors, consumer product goods Industries

·         Back Order Processing

The basic idea of back order processing is to carry out a new ATP check for a set of order items. This way backorder processing can also be used to distribute quantities in case of shortage according to priorities. Back order processing is usually performed in the background, but interactive backorder processing is also possible.
