Follow-on Processes in SAP ERP

Shopping carts can result in three types of follow-on documents:

Reservations
Purchase requisitions
Purchase orders

The follow-on documents are determined using Business Rule Framework plus (BRFplus). E-shopping delivers a standard ruleset with a decision tree, which you can, however, also override.

Follow-on Document Determination

The BRFplus function /SRMERP/F_DET_FOO_TYPE contains a default ruleset. Based on this ruleset, the system determines the appropriate follow-on document type as follows:

A reservation is created if the requested product has a valid product ID and an available quantity.
A purchase requisition is created if one of these conditions does not apply, for example, if the requested product is not on stock.

You can also create your own ruleset with a higher priority that overrides the default ruleset.

If configured in BRFplus and provided that the required data is complete, a purchase requisition can also result in an automatically created purchase order. To ensure that a purchase order is created even for those products that do not have a material master, for example, free-text items, you define rules for assigning material groups and purchasing groups in Customizing.

For more information, see Customizing for Materials Management under Start of the navigation path Purchasing Next navigation step Shopping Cart End of the navigation path .

The following examples illustrate the standard process:

Example Example

When employees enter a material master and the number of products they would like to order is available on stock, a reservation is created.
When employees describe the required product, a purchase requisition is created.
When employees order products from catalogs and the products do not have a valid product ID, a purchase requisition is created.

End of the example.
