Issue in Creating GSTR2 Report ,Unable To Find Assessable Value Data Source and add Storage Location

[shreshtha_pareek]

Hi Team,

Hope you all are doing great,

I am creating GSTR2 Report for Accounts Payable Process in SAP S4 HANA Public Cloud. It is a Compliance Report for India. Standard Report is not available so we are creating it by using CDS View app. I am facing Following Errors and unable to proceed further.

1. I have added Supplier Invoice Data source, while adding Storage Location from Material Document Item data source multiple entries are generating as there is no Data Source available for Line item like Supplier Invoice Item Data Source. Please advise Is there any way to add Storage location so that Multiple entries should not generate.
2. My client is using Custom Duty Process for which they are booking Custom Duty and GST on Assessable Value but in CDS View, I am unable to get the Assessable Value. Can you Please Suggest if any Data Source is available for Assessable value or How to add the Tax amount calculated on Assessable value. 

Thanks and Regards,
