I have encountered an error Revenues report (S_ALN_01001159) that cannot output self-defined value.
It is easier to trace the error in debug, but difficult to set break point in SQ01.
(for the detail of issue in S_ALN_01001159, you can check KBA note 1833038)
Manu: query -> more functions -> display report name
then we can set break point in the report in SE38.
2. go to INCLUDE LAQ_INT_FUNCTIONSF02 and put a break point in form SUBMiT_REPORT.
break <userid>. ( or break-point)
