Within a module, we have line items for entity, employee, currency, and account, with the module being dimensioned by time (month). The employee's entity and currency may change monthly. Additionally, there's another line item called Key, formed by concatenating the aforementioned four line items, and its time scale is also monthly due to the variability of both entity and currency on a monthly basis.
The problem emerges during the Key import, triggering an error message that reads, "Another row has already been processed with this key." Moreover, the ISFIRSTOCCURRENCE does not provide assistance in this case, as its time scale has to set to monthly and remains true for all months. Can anyone provide guidance on obtaining unique values when importing the list
