Dear Amit,
yes the data source is custom & we are using selection at infopackage. the data source was working in the last weeks. previously we can process one month data. but right now it is not working even for a single day. all transactions in the ECC side is displaying "transaction recorded" in the Infopackage analysis it is displaying the below message. but the background process on both side finished with sucess
Not all reported data packets arrived.
In the OLTP system you can check whether
the background processing was terminated.
