I am posting inventory document using transaction using MI10 transaction. I am debugging the standard code and have put a breakpoint at function module 'MB_CREATE_INVENTORY_DIFFERENCE'. No pressing F8 after entering the debugger is taking me inside this function module but my objective is to know how the tables that are input to this function module are getting populated.For this i have to go back in debugger just before calling this function module.Please tell me how to acheive this.Why i need this information is because i want to post inventory document directly from 'MB_CREATE_INVENTORY_DIFFERENCE' rather than MI10. For this i need to know whatall fields are required to be filled for successful posting and hence creation of MBLNR which is EXPORT parameter of this function module. PLease suggest how to do it.
