How to add field in InventValueReport

Hi everyone,

I make one field with name : Description. I want to get information from table  EcoResProductTranslation with field Description and insert this information in InventValueReport(InventValueReportTmpLine).

After I add field , which i make - Description , in InventValueReportTmpLine. I go to DP and insert field in macro.

After this I mean , i must go to InventValueReportPopulateItem , but I don't know how to implement code ther first to join tables and after this to insert information in field.

I will join table like this with little changes.
