Hi Asantos,
I presume that your company doesn't use Adagio MultiCurrency, thus there should be no need to set a currency code in any transaction, including when importing batches.
Does your data pass an integrity check? The more likely reason for this error is that the underlying code is blank somewhere in your data.
I tried with sample data and the default CSV Header Detail file and could not replicate a problem. I expect that your file layout is probably different than the sample layout.
I didn't find any known issues to do with importing batches failing on a blank currency code. You likely will need to get your Adagio Consultant involved in this.
