Notifications not generated through IE4N

Dear Experts,

Greetings for the Day!!!!!!

I wishing all the experts of EAM and thanks to every one. Currently i am facing one issue in EHP7 , i activated the LOG_ROTOSUB_1 & 2 business functions to execute the refurbishment maintenance order process along with serial number concept. I assigned the serial number profile and valuation category to generate the different valuation types to show the different stock information and stock balance.

When i want to replace the serialized material, i created the breakdown notification and maintenance order and assign the components with two different valuation types and release the order.

I am issuing / receipt the serialized materials through IE4N transaction code. While dismantling and installation system not creating the notification, i crossed all the configuration part and transaction part but still i am unable to understand the error.

Please guide me how to rectify this issue.

Regards

JKM
