'BAPI_POEC_CREATE' function doesn't work with extended classic scenario

Question

Hi everybody.
Antecedents:
We are working in an extended classic scenario.
When we create a Purchase Order via ITS in SRM, the system works ok, the PO is replicated in the ERP system.
But when we execute “BAPI_POEC_CREATE” function module in order to create a PO in SRM, no message are available in the application monitor, but the PO is not replicated in the ERP system.
Both exampled were created with exactly same data (partners, items, categories, accounts, …)
Moreover when we modify the second PO created via ITS, the systems doesn’t show any error message, we can order our PO again without error, but the PO isn’t replicate in the ERP system.
1. We executed “BAPI_POEC_GETDETAIL” function module, and there is only a difference between POs, E_PO_STATUS table.
PO created by transaction has 8 entries:
       I1009 X
       I1015 X
       I1021
       I1038
       I1039 X
       I1043
       I1080 X
       I1180
And PO created by BAPI has 5 entries:
       I1015 X
       I1021
       I1038
       I1043
       I1180
2. We run “BBP_PD” transaction, and there is only a difference.
PO created by transaction mode shows:
- Message: W BBP_PD 830 Default values have been taken from Vendor PRUEBA10/purchasing organization Área Global Compras (org. compras)
And PO created by BAPI
- Message: No Messages
Could anyone help me with the problem?
Thanks in advance.
Raúl.

Hi Raúl,
this is exact, BAPI_POEC_CREATE is designed to create local PO.
If you want to replicate it to R/3, then you have to change it to an ECS PO.
In BADI BBP_DOC_CHANGE_BADI, called at the real beginning of BBP_PD_PO_CREATE, you will have to change some data to enable the ECS scenario:
- change header subtype to EP
- change header log system to SRM (keep FI LS as is)
- determine a backend purch group & org
- complete BE fields (be_object_id, be_object_type, don't change be_log_system because it will be determined during the transfer, be_pur_org and be_pur_group will also be determined during the transfer)
- ... and maybe other R/3 relevant fields
Compare both PO one by one, and adapt the gaps.
