Can anyone help with a this problem? I have a large spread sheet with data
in the A column (Part Number). There are many records with duplicate part
numbers which have been sorted by this field so duplicates appear
contigously. The columns to the right contain volume by period. Each row
has volume for single period so for the 6 periods under study there will only
be data in one of the six columns.

I need to combine all the volumns into one line. Sometimes there are no
shipments for other periods so the number of contigous records vary. The
data looks like this:

AB 1
AB 4
AB 3
CD 6
SD 2
SD 4

Need this

AB 1 3 4
CD 6
SD 2 4

Any help is appreciated. Thanks
