Hi,

Thanks @ssmusoke for the dump file you shared. This actually has given me the real picture of how the module behaves. Actually there is something am missing now.

I don’t know what I should handle this but when exporting data, the Concept Resource makes the resulting data so bulky (Around 1GB) on a server with 2000+ Patients but without Concepts, its around 80MBs. Remember we have a limit of the file size which 75MB. I had not realized this before testing with large data.

So how should I handle this?
