Adapter Engine Not found in ID

Hi folks,

While creating a communication channel for File adapter the field for Adapter Engine is blank

I followed this link

/people/venugopalarao.immadisetty/blog/2007/03/15/adapter-engine-cannot-be-found-in-integration-directory

Business system was not there. so I tried creating a WEB AS ABAP acc. to this blog.

I got the following error :

<b>CIM_ERR_FAILED </b>

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.

Reagards,

Sachin
