When SD invoice created in one sap instance is sent as outbound message type INVOIC and based on inbound idoc of message type INVOIC ,AP posting have to be created in another instance.
Can we create another sap instance as LS and assign outbound message type as INVOICE and process SD09 .
So in output type shall we maintain as ALE?I did it .
Maintained condition record based on billing type on combination like billing type+payer+LS+SAPINSTANCE (SAPQ1) +A+4.
When output is triggered in Invoice,it provides error as partner should be LI or KU.
How to overcome this.
