@Darshana Herath Since this is a DEV environment I suggest you to run the Autobuilder and it will give you the detailed errors, which you can easily identify the issue.

Reason for such error should be due to a corrupt reference data in the database on foundation tables or views.

Thank you for the information. Below information was found after AB

Hi @Darshana Herath ,

A good place to start would be to look at the import log file for the models in the <ifs_home>\instance\<instance_name>\logs. This would give you the exact error that pops up when importing the models. 

Cheers.

I could resolve the issue by manually refreshing “dictionary_sys_tab”

The issue was with the below file(Package).

C:\IFS_YOUN1_DEV1APP8\repository\model\enterp\LogicalModel\FunctionalModel\ActivityGroups\CYiInterface\Activities
