Your question is a bit unclear but you can do this in a variety of ways in RapidMiner.  One approach would be to use Extract Macro or Generate Macro and Loop Examples to set these macros for each example in your dataset and then do whatever you are planning with this macro.

hello,
Problem is first case ,I have four column 
Attr_1    Attr_2          Attr_3            Attr_4
name    Sachin         product        Credit Card;Insurence 

next iteration I have two column 
Attr_1    Attr_2         
name    Sachin        
if i used extract macro then first case it works but in second getting error Attr_3 and  Attr_4 not present

You can fix this if you harmonize your dataset to ensure that all records have the same attributes, even if they are blank or missing.
