Hi @SaKhan ,
It looks like you’re encountering an error related to a duplicate value in the ‘EffortVariance’ column of your ‘Plan_Project’ table. This issue can occur if a column that is part of a many-to-one relationship or a primary key contains duplicate values.

Ensure that the ‘EffortVariance’ column does not contain duplicate values in your Plan_Project table.

in your data model, you have table called "Plan_project" and has an one to many realtionship with other table on column "Effort Variance". 

as per data model, you can not have duplicated value in column , if it has been used in one to many raltionship. so please update the relationship to many to many or remove  duplicated from data

Remove duplicates from excel sheet

That would work 🙂
