Hi Khush,
Hope you are keeping well. Recently I have been trying to create a initiator rule where by it checks for items containing SoD violations. Whilst Amanjit's blog (AC10.0/10.1: Create Rule Based on Risk Violation in Request, Using BRF+ Procedure Calls) does achieve this to a certain degree, the solution does not discriminate per individual line item, instead it looks for "atleast 1" violating item and the whole request is sent off to the specific path for approval.
I have tried to find out more about the "GRAC_INITIATOR_SOD_VIOLATIONS" Function Module, but found very little information on line. I am wondering if you may have more information about this FM or alternatively be able to explain with some more detail as to how your solution descrubed in this forum works. Is it able to scrutinise each line item individually?
Would really appreciate some experienced advice from you (and others) 
Look forward to the responses.
