Hi there,
the solution I was trying was multiple vlookup function. But it seems quite complicated and still it requires a lot of effort and time. Oracle DB gives me an Excel file with all the products in one column and its parts in second column. It could seem that there is only one level bills of materials (BOMs), but actually our products could have many levels with many parts inside. So, Oracle DB has an unique ability to code (hide) information from me by giving just one level product tree. And what I need is to transform the data to normal BOM. I do not know if I expressed clearly, so I attach the Excel file from which you can have better view on my problem. Oracle product tree transformation.xlsx
I need a way to transform data to the table format I provide because later I could use pivot table.
