I am downloading the data from excel file , Just for learning I want to know here for rate KBETR they are using try catch block so that any errors will be catched here , similarly for example if there is currency, quantity , sales order no and similar to this many fields how can we know what catch block is to be used. and where can we get these details .
TRY. wa_item-kbetr = st_input-value. CATCH cx_sy_conversion_no_number INTO oref . ENDTRY.
