Pentaho Reporting get previous Field












1















I am using PRD 5.3



I have a problem getting previous record



For example :



x | y | z | //start with 0
1 | 1 | 2 | //0 + 2
1 | 2 | 5 | //2 + (1 + 2)
4 | 4 | 13| //5 + (4 + 4)


I am using formula a like this, but I always get the wrong result.



=IF([index]=0;[totalsaldoawal]+[totalamountD]-[totalamountK];[totalamountD]-[totalamountK])


This is my formula:



if index = 0 // first row then [totalsaldoawal]+[totalamountD]-[totalamountK] else mustbe previous result + [totalamountD]-[totalamountK]


I tried to find some documentation like this but still doesn't help.
