You will learn multi dimensional aspects around GATP including real implementation experiences from the module. This article will explain important aspects of GATP. There are many other articles on GATP on this website, and in fact, this article links out to a number of these articles as it deals with various topics, but this article can be seen as the general introduction and broad overview to SAP GATP. The first question that often arises in regards to GATP is how it is different from availability checking, which is a functionality that is very familiar to anyone who gapt worked in SD or sales order processing.

Therefore this is a good place to start in attempting to understand GATP availability checking. This means that customers have a higher gztp of being satisfied with product, for a lower investment in inventory sao productive capacity. There are other differences, but this is a good starting point to determine if a GATP project is a strong opportunity at your company.

If the list above is all highly desired, then the next step is to check on the likelihood of getting funding for a GATP project. There are several ways to run availability checking. Ggatp is explained more fully here. However, because CTP gxtp still discussed, it is often considered a possible option. There is an ATP tree structure for each request schedule line in the sales order.

Introduction to SAP GATP aka Global Available to Promise • *Brightwork | SAP Planning

An ATP tree structure contains, among other things, the requirements data dates, quantities and sources of supply for the required finished products and components.

Of these alternatives, Multilevel ATP Check is the most complicated, and best suited for assemble to order operations. To find out more about these see this article. More explanation on this can be found here.

The major areas include the following:. A very large part of GATP is related to backorder processing. BOP, as referred to by SAP, list sales documents relevant for garp materials allowing for confirmation.

This sets a limit on the processing in term of how long the system can look forward and backward. The calculation profile can include the following:.

See this link for details. Here are the features of GATP:. That is it was a marketing rather than an engineering decision. However, it is argued that the memory resident liveCache allows better results — however given that GATP is implemented xap often in a very simply design, this argument seems a bit theoretical. The book Supply Chain Management with SAP APO has a very good description of the product availability check, which goes on to describe how pegging connects order objects at different levels.

This is an explanation which is often left out of most evaluations of pegging. Here is the quote:. This calculation is performed using time buckets of one day in the ATP time series live cache where all orders of a location product are stored with their quantities and their order category. These time series are displayed with the transaction category. Notice that Szp have gatpp declare the areas listed above.

If not a future ggatp can be entered and the availability check will be run for that date. These two are important fields to call out.

This is explained at this link. The operations of a business. The Business Event is made up of the following characteristics: However, because the real logic is maintained within the Check Mode, while the Business Event is necessary to populate, it is essentially an information field. After the green checkbox button is selected, we then are taken to the ATP screen, which in this case shows a very large quantity of stock which can be committed against any potential sales order.

The second time I populated the quantity field with a value ofand now the ATP has been performed for This is because I also changed the date of the ATP check. By double clicking this line item, one can be brought gstp into the setup of the ATP check.

Next, we will view what is referred to as the check instructions, by selecting the button at the top of the screen. Next, this screenshot comes up. These are all the options that appear for the Check Instructions. Notice that the Check Mode and the Business Event are right at the top of the screen. Next is when the check is to be performed, that is the Product Check, the Product Allocation that is against an allocation, or during Planning.

They are described as follows:. Below this is the Rules Based Avail Check section. I found this definition from a link I provided in the references:. 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. This is a functionality available in GATP. This is where the complexity of GATP really ratchets up, because there are so many options. Rules based AC has a number of configuration settings which include:.

There are so many areas to focus on, however, the Third Party Order Processing is of note. This allows processing to be performed against Contracts and Scheduling Agreements. There are many more…. The Check Mode is apparent when selecting to perform a GATP availability check as can be seen in the gattp screenshot.

The Check Mode comes from the Product Master, and therefore definable per product, and is the scope of the check that is performed combined with the consumption of the forecast. The Check Modes are made up of four characteristics, although in most cases it is really three characteristics as rounding profiles are rarely used. The final characteristic is really more of the name or description of the Check Mode — that is what the Check Mode is used for. For example, SAP gave up documenting fields and therefore many of the fields within one of the most important areas of GATP, called the Check Instructions, are simply copied over and over.

As far as the published material shortage, this surprising because GATP is one of the original SCM modules, so there has been plenty of time to document it.


While not implemented as broadly as SNP or PPDS, we can not think of a very good reason why so little is written on the module as it is a constant module of interest among clients. However, it describes many areas of functionality in GATP that I know very well are never implemented — for instance it describes how GATP supports transportation and shipment scheduling to determine material availability — that simply does not happen, and the SAP GATP will most often go off of lead times.

Furthermore, the number of options are so numerous in GATP. However the actual implementation of the options is much different, and this leads to the next point. There are some supply chain experts who dispute the implementability of SAP GATP because some of the data, such as the shipping lead time accuracy. The complexity of looking out across many locations and other dependent variables are not which relate to future inventory are typically of insufficient quality to make GATP a worthwhile endeavor.

One complicating factor with GATP is its product-location planning, as well as production scheduling along with an order commitment and inventory allocation system all in one. Software that tries to do too much can end up not satisfying any of the requirements. It is difficult for most companies to make improvements in supply planning without outside advice.

And it is close to impossible to get knowledgeable supply planning advice from large consulting companies. We offer remote unbiased multi-dimension supply planning support.

There is no one right supply planning method for all situations, even within one company! In fact, it is unnecessary to choose only one method, and using multiple supply planning methods is feasible and in most cases, has many advantages over using a single method.

This book explains why no one supply planning process meets all requirements and lists the many wap of using multiple supply planning methods. The book is also useful as a general document on how multi-methods can be used in supply planning applications. Want to find out? Why some supply chain experts question the implementability of GATP.

Different levels of hierarchy can be checked. GATP offers the ability to perform a global multi location check. Availability checking provides a more simple response to a request than GATP. GATP looks out across many different plant to attempt to fulfill a demand.

Ways of Running Availability Checking There are several ways to run availability checking.

Gaatp major areas include the following: The calculation profile can include the following: Accepted number days early Consumption Limit: Number of days that prevents a requirement using receipt and stock that are too early.

Value maintained is taken into account in following checks. Here are the features of GATP: The order checking begins in SD when the order is tested.

For instance, in DP, a statistical forecast is generated. Here is the quote:
