Help me to derive new field iteration number based on my scenario?

durgabhavani — Thu, 19 Apr 2018 05:29:41 GMT

Hi All,

Please help me to derive new field iteration number based on below scenario. I am assuming Peek function needs to be used to derive the field. Please find the scenario in detail and expected output.

1. Group iteration number needs to start assign number from first time category "CAP" and Group GS.(here find example highlighted 1)

2. Group iteration needs to increase number when it changes from category "CAP" to "CAP and from Group BUS to GS or "CAP" to "QC" and from Group BUS to GS. (here find example highlighted 2).

3. Finally Group iteration needs to change until the category changed to "QC" and from Group BUS to GS. (here find example highlighted 3). Here after no need to change the iteration number irrespective of change in category or group.

Please let me know if any questions. Thanks in advance.

Sample data and expected output column:

ID	Category	Group	Group_iteration (Expected Output)
101	CAP	FCR	0
101	CAP	GS	1
101	CAP	BUS	1
101	CAP	BUS	1
101	CAP	BUS	1
101	CAP	BUS	1
101	CAP	GS	2
101	CAP	GS	2
101	CAP	GS	2
101	CAP	BUS	2
101	CAP	BUS	2
101	QC	GS	3
101	QC	GS	3
101	CAP	BUS	3
101	CAP	GS	3
101	APP	BUS	3
101	CAP	GS	3
101	QC	GS	3
101	CAP	GS	3
101	QC	GS	3
101	APP	BUS	3
101	CAP	GS	3

Thanks,

Durga

I think this load script might work for you:

DATA:
LOAD
  RecNo() AS R#,
  ID,
  Category,
  Group,
  If(ID<>Peek('ID')
    ,0
    ,If(Group='GS' AND Peek('Group')<>Group AND Peek('FI')=0, Peek('GI')+1, Peek('GI'))
  ) AS GI,  // Group_iteration
  If(ID<>Peek('ID')
    ,0
    ,If(Category='QC',1,Peek('FI'))
  ) AS FI  // Finished Indicator
INLINE [
ID,Category,Group,GI
101,CAP,FCR,0
101,CAP,GS,1
101,CAP,BUS,1
101,CAP,BUS,1
101,CAP,BUS,1
101,CAP,BUS,1
101,CAP,GS,2
101,CAP,GS,2
101,CAP,GS,2
101,CAP,BUS,2
101,CAP,BUS,2
101,QC,GS,3
101,QC,GS,3
101,CAP,BUS,3
101,CAP,GS,3
101,APP,BUS,3
101,CAP,GS,3
101,QC,GS,3
101,CAP,GS,3
101,QC,GS,3
101,APP,BUS,3
101,CAP,GS,3
];


DROP FIELDS R#,FI;
RENAME FIELD GI TO Group_iteration;
