PO on R/3 not created from SRM Bid

Question

Hello,
I create a contract on R/3 from a bid without problem but when i try a PO it is created only on SRM.
I´m using classical scenario, i define the backend system on
IF_EX_BBP_DETERMINE_LOGSYS~DETERMINE_LOGSYS
using
loop at item_data into line.
line-logical_system = 'BACCLNT202'.
line-logsys_fi = 'BACCLNT202'.
modify item_data from line.
endloop.
I implemeted bapi BBP_CREATE_BE_PO_NEW and BBP_CREATE_PO_BACK but the program dont go through them.
Do i miss some customizing??
Regards,

Hi,
We are having a very similar problem. 
We have used the BADI  BBP_DETERMINE_LOGSYS~CONTRACT_LOGSYS_DETERMINE.
If you look at the documentation for this it says:
"In the standard system, the system creates contracts locally from Sourcing and SAP Bidding Engine You can use this BAdI to determine a backend system.  The local system used by the standard system to create contracts is XYZ4711. In the field CV_LOGSYS, you enter the logical system ABC0815 that links to a backend system. In this way, contracts are created in the backend system."
Based on this information we put the following code in this BADI:
CV_LOGSYS = 'CSC_Q01030'.
But it still appears as though the system is trying to create a local PO. 
When we goto SM21 we see the following error:
BBP_PD 396 Purchase orders cannot be created without IPC pricing
This indicates that the SRM system is still trying to create a backend document or a local purchase order.  We are using the classic scenario (not extended classic) and want a backend R/3 document.
Can you check SM21 in your system as well as look at the METHOD that we have used and try it in your system?  Please let me know if any of this information helps or if you find another solution, maybe we can trade notes and resolve both of our issues!
