Question about execution lists in JDE AR Auto Receipts Match

  Hello, I have a Q on execution lists in JDE AR Auto Receipts Match. In my scenario, I am using Line of Business and have a customer record set up for Co 00000 only. Now lets say the execution list in Customer for Co 00000 record is STANDARD. My understanding is JDE processes in hierarchy "Customer Master ---> R03B551 ---> R03B50" as in setting for execution list @ Customer Master would be overridden by R03B551 processing options which would itself be overridden by processing options of R03B50. Would it be any different in my scenario wherein despite using LOB, I only have record setup for customer for Co 00000 and that has STANDARD execution list. As per my test, "execution list" values in R03B551 and R03B50 are ignored and customer master setup is being used. Pls let me know your thoughts.
