Hi,

If you are already on release V5R4, you may use the OLAP-Ranking function
DENSE_RANK.

Select FiscYear, CtlGrp, SrcCode, 
       Dense_Rank() Over(Order By FiscYear, CtlGrp, SrcCode) as SEQ
> From YourTable
Order By FiscYear, CtlGrp, SrcCode

Mit freundlichen Grüßen / Best regards

Birgitta Hauser

Given the following data:
 FISCAL      CONTROL   SOURCE   SEQ
 YEAR           GROUP       CODE          #
  2,007                1                AP             0
  2,007                1                AP             0
  2,007                1                AP             0
  2,007                1                JE             0
  2,007                1                JE             0

  2,007                1                CS             0
  2,007                1                CS            0 
  2,007                1                CS            0 
  2,007                1                CS            0 
  2,007                2                JE            0

  2,007                2                JE            0 
  2,007                2                AP            0 
  2,007                2                AP            0 
  2,007                2                AP            0 
  2,007                2                AP            0

Is there any method using dynamic SQL (no user defined functions or any
other type of sql program), to set a sequence number so that when Year,
Control Group or Source Code change, the value will be incremented by 1
starting at 1? I have tried the Row_Number() Over function, but have not
been able to get it to do what I want.

The desired result would be:
 FISCAL      CONTROL   SOURCE   SEQ
 YEAR           GROUP       CODE          #
  2,007                1                AP             1
  2,007                1                AP             1
  2,007                1                AP             1
  2,007                1                JE             2
  2,007                1                JE             2
  2,007                1                JE             2
  2,007                1                CS            3
  2,007                1                CS            3 
  2,007                1                CS            3 
  2,007                1                CS            3 
  2,007                1                CS            3 
  2,007                2                JE             4 
  2,007                2                JE             4 
  2,007                2                JE             4 
  2,007                2                AP            5 
  2,007                2                AP            5 
  2,007                2                AP            5 
  2,007                2                AP            5 
  2,007                2               AP             5
