Function documentationAvailability Check Using SAP ERP

 

If you perform material requirements planning in SAP ERP, you can perform an availability check (ATP check) using SAP ERP in the business transaction in SAP CRM.

Prerequisites

In SAP ERP

In SAP ERP, you must activate the business transaction events (BTEs) for the Availability Check Using SAP ERP. To set this flag in SAP ERP, do the following:

  1. Enter transaction FIBF.

  2. Choose Start of the navigation path Settings Next navigation step Identification Next navigation step SAP Applications End of the navigation path.

  3. Enable the CRMATP application.

In SAP ERP, the material must not be relevant for the availability check with SAP APO.

In SAP CRM

In SAP CRM, you change the setting to availability check using SAP ERP in Customizing for SAP Customer Relationship Management under Start of the navigation path Basic Functions Next navigation step Availability Check Next navigation step Availability Check Using SAP ECC Next navigation step Define Middleware Parameters: Availability Check Using SAP ECC End of the navigation path.

For information about settings for availability check in SAP ERP, see Customizing for SAP ERP under Start of the navigation path Sales and Distribution Next navigation step Basic Functions Next navigation step Availability Check and Transfer of Requirements End of the navigation path.

Features

When you perform the availability check using SAP ERP, the system performs the following functions:

  • Transfer of requirements to production or purchasing

  • Reservation of stock

  • Shipping and transportation scheduling

SAP ERP transfers the results of the availability check to the business transaction in SAP CRM.

You can use the following processes in SAP ERP in combination with the availability check using SAP ERP:

  • Transportation and shipment scheduling to determine the material availability date

  • Follow-up activities such as outbound delivery and goods issue

  • Product allocation

  • Backorder processing

    Note Note

    The system does not set the order status to Newly Scheduled.

    End of the note.

SAP CRM then automatically triggers a new availability check, among other things, when you perform one of the following actions:

  • Change the quantity

  • Change the requested delivery date

  • Change the schedule line

  • Remove the cancel reason code

During an availability check, the system takes into account the following data transferred from SAP CRM to SAP ERP:

  • Order type

  • Sold-to party

  • Product

  • Quantity

  • Account

  • Unit of measure type

  • Requested delivery date

  • Sales organization (at header level)

If you use SAP ERP 6.0 or a higher release, the system also takes into account the following data transferred from SAP CRM to SAP ERP during an availability check:

  • Plant or vendor

  • Ship-to party

  • Batch

  • Item Category

  • Requirement rule (fixed date or quantity)

  • Shipping conditions

  • Weighting

All other data is redetermined in SAP ERP. For example, Incoterms changed manually in SAP CRM are not taken into account in the availability check using SAP ERP. This means that the result of an availability check of an order created in SAP ERP may differ from that of an order created in SAP CRM.

Note Note

Choose a release and then Application Help. In SAP Library, choose Start of the navigation path SAP ERP Central Component Next navigation step Logistics Next navigation step Sales and Distribution (SD) Next navigation step Availability Check and Requirements in Sales and Distribution Processing End of the navigation path.

End of the note.
