How to pass parameters as your transaction names in Loadrunner

 Consider a scenario where you have to get transaction response time for the different sizes of file upload. Here the file upload request will be same and we have to print the file size in the transaction name so that we can map the response time with the corresponding file sizes.

lr_start_transaction(lr_eval_string("07_FileUpload_02_Choosefile_{P_File_Size}_Submit"));

File upload request

lr_end_transaction(lr_eval_string("07_FileUpload_02_Choosefile_{P_File_Size}_Submit"), LR_PASS);

P_File_Size is the parameter which has the file size. Say for example if you have two file sizes of 1MB & 10MB, you will get two transaction for the file upload in your analysis report.

Output:

07_FileUpload_02_Choosefile_1MB_Submit

07_FileUpload_02_Choosefile_10MB_Submit

How to pass Parameter values as Boundaries to the correlation function in loadrunner

When you want to pass the user defined parameter as left or right boundaries, you can directly pass the parameter as boundary values. In the below screenshot you can see that P_Server is the user defined parameter and it has been directly passed as the Left Boundary.

When you want to pass the Correlation parameter as left or right boundaries, you have to pass the parameter as boundary values using lr_eval_string function only.. In the below screenshot you can see that P_Server is the correlation parameter and it has been as the Left Boundary using lr_eval_string function.
