We regularly upload bulk assignment changes to Production and we have concern raised by business users from different countries that the future changes for some employees which are manually created by HR got deleted. We are not able to identify the HDL files which has caused this issues as the files are marked for purging after the data load. 

 

We need to identify the HDL files which caused this issue and also all those employees impacted so that we can ask the HR teams to recreate the future changes.
