How to merge multiple data for each date

ZZB — Sat, 15 Nov 2014 06:43:08 GMT

I have the following dataset. I want to merge the amount of IID in the same day for each ID.

How to convert the data in the left into the data in the right? It does not matter for IID.

Thanks

ID Date Volume IID Amount ID Date Volume IID Amount

1001 01/12/1980 50000 01 10000 1001 01/12/1980 50000 ? 14200

1001 01/12/1980 50000 03 200 1001 02/13/1980 55000 ? 14123

1001 01/12/1980 50000 02 4000 ==> ....

1001 02/13/1980 55000 01 10009 1009 01/12/1980 70000 ? 10200

1001 02/13/1980 55000 03 234 1009 02/13/1980 79000 ? 10243

1001 02/13/1980 55000 02 3880

....

1009 01/12/1980 70000 01 10000

1009 01/12/1980 70000 03 200

1009 02/13/1980 79000 01 10009

1009 02/13/1980 79000 03 234
