User Exits for Devt. Class MEW - BAPIs
The BAPI ProcurementOperation.GetInfo (function module BAPI_PROCOPERATION_GETINFO) determines which object is to be generated on the basis of the item data and the Customizing settings. The value determined is passed on in the field OBJ_TO_GEN in the table PROCUREMENT_ITEM.
The following values generate the following objects:
3 Purchase order
The field OBJ_TO_GEN can also have the value 4 (other usage). In this
case, no object is generated. For example, in the Internet application component Procurement via Catalogs , the item data is shown on the confirmation screen if the value 4 is returned.
With this enhancement, you can change the value determined in the field
OBJ_TO_GEN. After the return of your value, the objects are created in the SAP System.
In Customizing it has been specified that reservations are always to be generated. However, in the case of material type ABCD, you wish to generate purchase requisitions. You then return the value 2 in the field OBJ_TO_GEN.
