Trying to load data from an external system (SAP Environmental Compliance, not R / 3) data in BW.
EC uses 3.x Data Sources. I had not worked with 3.x Data Sources, only RSDS Sources.
For data transmission needs only start infopackage? All standard infosourses and rules for active are active.
After start InfoPackage in Manage of DSO (Data Target) minotor shows:

Request still running
Diagnosis
No errors found. The current process has probably not finished yet.
System Response
The ALE inbox of BI is identical to the ALE outbox of the source system
or
the maximum wait time for this request has not yet been exceeded
or
the background job has not yet finished in the source system.
Current status
No Idocs arrived from the source system.
In source system in EC Log Viewer - Destination for BW Extraction is not available!
Does anyone have any experience or ideas?
