Issue with "Service Order All" in v8.1.1.2

Hello,

Issue:  One of my Customer is facing error during Service Order# generation after clicking on “Service Order All” button where there is more than two product records in Activity-->Item View

 

Research:

 

1. As per expected behavior, when user clicks on Service Order All button, it should create a  Service Order and respective Service Order Id should populate against each product line item in activity-->Items(Parts Movement) view.

2.  When customer added two product records under activity-->Items(Parts Movement), Service Order All functionality  is working fine

3. But When customer added three or more product records under activity-->Items(Parts Movement), Service Order All functionality
