Where-Used function doesn't list all hits.

Hello,

the result list of Where-Used function in ADT is significant shortly as the same list in SAP GUI. The list is not full even for the where-used call for a variable, which used in one programm only. It happens without any error messages in ADT.

Could you tell me the reason of it please?

ADT version 2.36, SAP 7.31 sp13

Thanks!
