Invoice posting is not triggering idoc message in EBP to FI backned ECC6

Question

Hi ,
We are working on classic scenario with SRM 5 having EBP and SUS on separate clients on same srm system.
Now we are extending standlone scenario for selected product categories .
We have created product master ,product category & vendor master in SRM EBP client. Defined below settings
1.Define Sourcing for Product Categories -local
2.Define Objects in Backend System  -EBP of type Local
3.Define G/L Account for Product Category and Account Assignmet
We are able to create Shpping cart ->purchase order( local)->confirm goods & invoice for local product
With  central ccountant authorization employee user has created the invoice  and resulted status of invoice as
"Currently Being Transferred" , expected   to post the invoice in ECC system but after invoice idoc is not getting generated in SRM in order to  transferred to backend  ?
I have tried and in debug mode found that ,Logical System of Logistics Backend is wrongly
attached to invoice ie instead of ECC logical system it is appearing SRM Local logical system . After changing the
backend value  for invoice header -BE_LOG_SYSTEM from srm to ecc backend & executed
FM-BBP_PROCDOC_TRANSFER  for particular invoice ,Idoc Basic type        BBPIV01 is generated and passed to ecc.
But not able to identify why wrong "Logistic backend " is appeared in invoice. we have below attributes maintained in
Employee

Company Code                                         BUK     100

Kindly help me to post the invoice to ECC backend ,

Answer 1

Thanks Sheetal,
We have classic scenario in place so ECC system (LOGSYS250 ) is defined as backend system  of type- ERP_2.0   &
FIvalid- realtime backend validation .
We are using  ECC is the accounting system defined  in the configuration setting Define Backend Systems.
Note: More to add that Invocie idoc generated after  backend logical system correction in invoice header data  of SRM ,
it is posting invoice successfully in eCC backend .  So  data correction for logical system value is seems  some problem with standlone scenario configuration . 
We have validating this scenario for selectd product categories as  with SRM 5 version in place,  customer is intrested to use Invoice management system ie.   invoice should be validated with exceptions  in SRM before posting to ECC.
We have EBP & SUS in different client on SRM system ,so  in existing  classical scenario   invoices created in SUS  against ECC backned purchase orders is  not flowing to IMS in EBP . Can you help me to validate the scenario ?
Regards,
Santosh

Issue is resolved  . It is the System Alias for Accounting Systems setting in organization  module .
Now with completion of workflow  idoc message-BBPIV is generated in SRM and successfully posting in ECC.
Thanks a lot for your inputs .
