When creating a delimited file source, there is a “Number of Lines to Skip” field in “Additional Settings” under the source configuration.The default value is “1”.However, IdentityNow skips the first two lines of the delimited file import and starts reading/aggregating data from the third line of your delimited file source skipping the first account.
If you insert a value as “0” (the non-default value) and save the configuration, IdentityNow will read/aggregate all the accounts successfully.
This sounds like a bug on our end. While I do appreciate you highlighting a solution to this, can you please open a support ticket as well? We need to get this fixed since the default behavior isn’t correct.
