Inbound Idoc Generation

Question

Hello All,
We have a ALE concept to transfer data between clients. We have made the settings and the process was fine. But on some days Inbound Idoc is not getting generated with respect to the outbound Idoc, and after some times once again system comes to normal state and the idoc generation is fine. How ever we dont have any root cause for the failure of Idoc generation. Could someone let me know where i can chk the info and what all the parammetres needs to be checked.
Note ; There are no issues in ALE ocnfig settings.

Hi ,
See the following code :
