While creating a communication channel for File adapter the field for Adapter Engine is blank
I followed this link
Business system was not there. so I tried creating a WEB AS ABAP acc. to this blog.
I got the following error :
Qualifier MAX(1) violated for property reference SAP_XIIntegrationServerLogicalIdentity.SameElement
however it's creating a Business System. but I am not able to find the adapter engine in ID.
