I saw few posts on how to do ABC analysis, but there were no concrete answers.
To summarize the requiement (say based on Good Receipt Quantities):
1. Top 25 -> indicate as 'A'
2. Bottom 25 -> indicate as 'C'
3. Records between 25 to 75. -> indicate as 'B'.
SAP How to paper(How to.. Realize an ABC Analysis) is on counts and not on cummulative %.
I used CKF, but it is only for display.
I used conditions, but it does not give the middle B records.
The last option would be VB macro, but then this would be not be a fantastic solution, as SAP Query can do ABC analysis, but BW Query would not be able to!!!
