I am using LSMW BAPI method for good receipt. I am using Business Object BUS2017 method CREATEFROMDATA. I notice that I need to setup the port at Settings > IDoc Inbound Processing. Can anyone explain what is this for? And also at Maintaining Port, I need to create a new port. What should I input for Directory, Function Module and Outbound File? Currently I set Directory to the path where I saved the text file and the text file name for Outbound File. How about Maintain Partner Number? Is that necessary? Without the setup, currently I encounter problem at step 13: Start IDoc Generation with error 'GOODS_RECEIPT.lsmw.conv' File Has Not Been Accepted for Processing'.
