Duplicate ID in purchase receipt

Hello. I am getting duplicate ID’s in the report which I export from purchase recepit. Please tell me how can I fix that.

You might be exporting child tables as well. Each child table row occupies single row in the excel sheet and causes repetition of parent values.

What is the solution for this. Guide the solution please

Remove all child table columns from your report.

Please see this image. I have to apply filters or I have to do something else? I am new in erpnext so I will be very thankful for you help.

Towards the right, there will be some columns which are of child table. Click on it and click remove.

Or click on Pick Column from Menu and remove all child table fields.
