what is best way to find the code customized?
I have to modify code on Retrunorder process(Sales Order-Pick and pack- packing slip journal)
then, When user cancel the order from the form, there is some of code that insert record into customized table A.
but I have no idea where is code to insert record into Table A.
I tried to find code from Cancel button. It seem that calling to SalesFormLetter Class.
So, I want to know if there is any way to find the customized code.
maybe Cross-Reference is useful for this situation?
