Function Module where-used list does not find update rule programs

Question

We have function modules called in update rules. The where-used list in the function builder does not find the update rule programs.
For example, function DATE_GET_WEEK is called in an update rule to InfoCube YCUBE001. The activated program name for this update rule is GP3PWI6PKM5Y3K75A370DIS8I77. When I goto SE37, enter the function DATE_GET_WEEK, click the where-used button, check the programs option and search. The system does not find the program GP3PWI6PKM5Y3K75A370DIS8I77.
Without this search capability it is difficult to do an impact analysis of changing function modules. Does anyone know of a solution?

Answer 1

hi,
i think the reason is the code of update rules' generated program are stored line by line in table(rsaabap), update rules program itself stored in table rsupdrout, link with field codeid, another useful table is rsupdinfo which store infocube, infosource related.  other info may stored in some other rs* and rsa* tables.
try to create following program in your system, and run, type in the function module name, and will display out the update rules program id, with additional useful info : which infoprovider, infosource, and detail info of the routine and infoobject in the update rule that using that function module. you may modify the program to have better display out list.
hope this helps.
