“Siebel _Star_Array” is a function generated by LoadRunner for correlating Siebel field values separated by Token "*". A sample format of the server response is given below and these field values are required to pass to the subsequent requests.
"1*N9*1-18506217*GEOFFTH4*Open10*Unassigned3*OEM12*Hardware-OEM14*Administrative1*01*010*Symptom X18*MSE-Perf7*GEOFFTH1*112*Geoff Thomas1*10*6* Normal19*10/16/2002 03:40:127*Sev - 47*1-13NY5"
Last Character/s (Highlighted in Red) in each of the fields denotes the length of the next field values. Because of which left and right boundaries will be dynamic and difficult to correlate.
The below "siebel _Star_Array” function provided with LoadRunner has some limitations and does not work at all times. It is it is tough to debug the errors without the source code
web_reg_save_param("WCSParam96",
"LB/IC=`ValueArray`",
"RB/IC=`",
"Ord=10",
"Search=Body",
"RelFrameId=1",
"AutoCorrelationFunction=flCorrelationCallbackParseStarArray",
LAST);
The sample code I had created can be used to parse the response and use it for correlation when compared to the Loadrunner Automactic Correlation
