Could you please suggest how to hide Cash desk Clearing Account.
Ask your developer to use EVENT 6015 Cash Desk: Ready for Input... you can use this to make fields hidden, optional etc..
The setting is V_TFK100A-XCLAC. Go to transaction SM30, input view V_TFK100A, chose the appropriate application area and look for field "Display Cash Desk Clearing Account" (XCLAC).
make sure this field is not set.
Thanks this option works
