Thanks Aleksandr for your response.
I was using the same FM to generate the IDOC xml from IDOC number. This XML file is being ignored after import and there is no proper error message why its been ignored in logs(SLG1). Thats the reason i requested for sample Customer - IDOC xml.
I have done extensive seach on SDN but i couldnt find the sample file. Can any one help me on this please?
