Yes, there is a reason to do this on the client side.
Because it's difficult to report on variables and combine the data with multiple tables, I've created a custom table to hold the variables of the MRVS. When the RITM is created, I run a before insert business rule on RITM to copy the MRVS data to the custom table. However, it is possible to update the MRVS data in the RITM after it's been created and I need to capture the updates in the custom table, but, I don't have a unique identifier to know which row got updated. I would like to create an "on update" business rule on the table sc_multi_row_question_answer but I don't have any way to match the row with the row in my custom table. I would love to be able to get the row_index from the MRVS and add it to my custom table but so far I've not been able to figure out how to do that, so I decided I would create my own rowid in the MRVS and use that in combination with the requested item number as a unique value.
If you have a better way to accomplish this, I'm all ears!
