How to add a new field in Sales Quotation Report in AX2012?

Hi,

Now I am working in Sales Quotation Report Customization in AX 2012. I am adding 2 fields(DlvMode,DlvTerm) in SalesQuotationHeaderTmp Table and assign these 2 fields in salesQuotationDP class(setSalesQuotationHeaderTmp method)

SalesQuotationHeaderTmp.DlvMode = CustQuotationJour.DlvMode;

SalesQuotationHeaderTmp.DlvTerm = CustQuotationJour.DlvTerm;

And I am placing this 2 fields in Report and deploy it.

next I run the report it gives error: SalesQuotationHeaderTmp.1.DlvMode does not exist in the report data provider Table                                                                                                                                                                                       SalesQuotationHeaderTmp.

I am trying this fields in different systems, it gives the same error.

Please give a suggestion How to rectify this.

Thanks,

Balu
