Functionality

This function module enables you to obtain availability information from one of the ATP services. The module directly accesses the corresponding service without using the CRM order. Note: Only availability information can be obtained. When obtaining information, no temporary or reserving objects are left in the target system of the relevant ATP service. This is not permitted, as there is no reference to an order. If you wish to create reservations, a reference (order) must exist; in this case, it is recommended to use CRM_ORDER_MAINTAIN. Reservations without a reference (order) will not be supported because a reference (order) is a prerequisite for a reservation. This is a basic principle of all ATP services such as Global ATP in APO.

If you wish to use an ATP service, you need to ensure that it provides a feature for availability information only.

Whether the ATP information outside of the order produces the same results as the ATP information within order processing depends on the order context provided. The context also determines whether a quantity conversion into the base unit of measure is possible. If, for example, the information PRODUCT_I is missing, conversion is not possible and the caller must transfer the quantity in the base unit of measure. Another important factor is the FIELDCAT, when using SAP standard ATP services,such as the APO system or R/3. You must ensure that the order context provided is sufficient to construct an adequate FIELDCAT. This is carried out automatically, and no effort is required from the user. If you use APO, you should specify a corresponding profile in IT_ITEM.

Alternatively, you can specify a FIELDCAT explicitly, or you can configure the ATP system in such a way that no or very little FIELDCAT information is required in order to obtain correct ATP information. Therefore there are different ways to transfer field catalogs.

IT_FIELDCAT_CRM transfers the FIELDCAT fields in CRM format. If necessary, they are converted to the R/3 terms and formats using the currently available means.

IT_FIELDCAT_R3 transfers the FIELDCAT fields in R/3 format.

At present, only one reference document (order) is supported. A list of orders will be supported in a later release.

Example

Notes

You do not necessarily have to work with GUIDs. You can also enter numbers as references in the GUID fields.

For some services you can define in CRMT_ATP_ITEM-MODIFY_TMP_OBJ that you only require the information once. This field then overrides other possible settings.

In order to determine which order contexts are necessary in which environment for automatically configuring the field catalog, you can create a corresponding order. Before doing so, you set a break point in CRM_CONFIRM_PREPARE_FIELDCATLG and observe the data returned by CRM_CONFIRM_GET_ITEM_DATA. This is generally the superset, which means that you must differentiate to be able to obtain the data you really need. This depends on the business environment.
