Cannot create a record in Price history(MCRPriceHistory). Price/discount type: Item price, The record already exists.

I got the below error while trying to upload/creating the sales orders.

Cannot create a record in Price history(MCRPriceHistory). Price/discount type: Item price,
The record already exists.


Solution:

Change the Next number for the price/discount in number sequence.
In my case the next number was 1066 and I changed it to 1067

To find the number sequence.
Accounts receivable > accounts receivable parameters > Number sequence > price/discount journal number.
