Create service Purchase Order automatically at goods issue in VL02N.

Question

Hi Friends,
Please give me steps on how to write the ABAP code To Create  service PO automatically at goods issue.
Technical Info
•     BAPI BAPI_PO_CREATE1 is to be used for creating the service PO.
•     The service PO will be only created for YLF deliveries.
•     The PO will be created only if the shipping conditions field ( LIKP-VSBED ) has any value except 3rd party or Customer pick-up.
•     The PO needs to be created when goods issue is performed on the delivery.
•     The PO needs to be created with the following values :
1.     Purchase order type : YB
2.     Vendor : Header partner function SP, Carrier
3.     Plant : LIPS-WERKS
4.     Material : 10
5.     Account Assignment Category : K
6.     PO Quantity : 1      
7.     Net price : LIKP-NETWR
8.     Cost Center : 54434
•     On failing to save the PO, the error message should be generated so that the user knows the error and can fix the error and create the PO manually.
Please help for this urgent req.
thanks.

Answer 1

Sure. Here it is:
Go to SPRO.
Logistics Execution
  Transportation
    Shipment cost
      Shipment cost document
         Shipment cost type and Item category.
For the shipment cost item category you are processing, lets say standard 0001 (Transportation costs). double click on it.
You will find all you need in the tab SETTLEMENT.
There, there is a field GENERATE PO.
Select one of the options:
     Do not generate purchase order
A     Generate purchase order for validity period of 1 day
B     Generate purchase order for validity period of 1 week
C     Generate purchase order for validity period of 1 month
Once the shipment cost is created and transfered to MM(settled), if there no open PO for the carrier, the system creates one.
Good luck,
