Hello,
We are using the Data management import process using "Customer Payment journal" entity to upload customer payments done outside of MS Dyn 365. It was working fine until last month and it is giving the following error during import process. I have checked the staging table to make sure the Journal Number does not exists. I also tried uploading with a very big journal number which is also giving same error.
Error
-----------------------------------------------------------------------------------------------------------------------------
File contains duplicate rows, Cannot insert data into staging due to unique key violation-
"0" Customer payment journal" records(s) inserted in stating.
