I have been struggling with this for the past couple of days. I'm hoping someone can provide some code to do the following: I receive comma delimited files that have 3 fields; part number , quantity and designator. The part number field may or may not be duplicated. If it is duplicated I need to merge the remaining 2 fields together adding the quantities together and sorting and adding the designator field so it is in increasing order. I then need to write this back out to a comma delimited file.
Here is a sample on the input file: 
032-00751-0000,1,R383
032-00794-0000,6,"RP1,RP2,RP3,RP22,RP24,RP26"
032-00795-0000,8,"RP10,RP11,RP12,RP13,RP14,RP15,RP16,RP17"
032-00804-0000,7,"R7,R14,R21,R23,R41,R42,R49"
032-00807-0000,2,"RP18,RP19"
032-00807-0000,4,"RP8,RP9,RP200,RP201"
032-00808-0000,3,"RP21,RP23,RP25"
032-00820-0000,5,"R966,R970,R971,R1041,R1076"
032-00820-0000,1,R3000
032-00893-0000,1,R1164

Note that there are 2 duplicates 032-00807-0000 and 032-00820-0000. Also note that if the designator field contains only one item there are no "". Here is what the output should look like: 
032-00751-0000,1,R383
032-00794-0000,6,"RP1,RP2,RP3,RP22,RP24,RP26"
032-00795-0000,8,"RP10,RP11,RP12,RP13,RP14,RP15,RP16,RP17"
032-00804-0000,7,"R7,R14,R21,R23,R41,R42,R49"
032-00807-0000,6,"RP8,RP9,RP18,RP19,RP200,RP201"
032-00808-0000,3,"RP21,RP23,RP25"
032-00820-0000,6,"R966,R970,R971,R1041,R1076,R3000"
0032-00893-0000,1,R1164

Also the designator field can get pretty big, quantities around 2000+ are not unheard of.
Any insight in how to tackle this would be appreciated.
Thanks!
