Hello All

We have a Fulfillment script in 1.0 that pulls a Serial number from the custom record based on SKU and other parameters. There is a seach that is created based on SKU and the fist available record is used. One of the criteria for search is that thee is no end user associated with the key.

We are working on converting the script to 2.0. What I am unable to figure out is, if the script(say the above functionality is put into Map function for a MR script) will run on multiple queues/instances, does that mean that there is a potential chance that 2 instance might hit the same entry of the Custom record?  What is a workaround to ensure that X instances of Map function dont end us using the same SN/Key? The way this could happen in 2.0 would be that 2 instance of Map make a search request on Custom record at same
