Hi Goutam
As seen above, after processing, this code is calling FM 'ZWF_SEND_RESPONSE_MAIL' to send the email - it is passing the contents in lv_content. Check this Fm now.
The Idea is to track the point where that email is getting created - that is where we need to see how "Remarks:" are being read.
Suggest you try doing a dry run of the entire chain yourself? If that does not helps, do a debug of the code.
Before you post the code of 'ZWF_SEND_RESPONSE_MAIL' over here, first see if this FM is sending the email or is it calling another 'Z' FM to do the job.
Regards,
Modak
PS: Your coding reavels your client and people who worked ...kindly try to mask that information
