Convert Data From Columns To Rows

I have a spreadsheet that consists of columns of data and I need to covert it into rows depending on how the data is set up. In column A, there is a list of invoice numbers. Columns B, C, & D are as follows:

Column B: Sales Rep Name
Column C: Sales Rep Number
Column D: Sales Rep % Split

I want to have a single row for each unique invoice number. As an example, I have the following:

Row 1: invoice ABCD-1234 Sales Rep 1: 55%
Row 2: invoice ABCD-1234 Sales Rep 2: 25%
Row 3: invoice ABCD-1234 Sales Rep 3: 20%

I want the output as follows:

Row1: invoice ABCD-1234 Sales Rep 1: 55% - Sales Rep 2: 25% - Sales Rep 3: 20%

I have attached a sample workbook with two sheets; one containing the raw data and the second, which shows the desired output.
