All info structures are part of the LIS (SPRO / Logistics General / Logistics Information System)
try T-Code MC26 ("Mantain update rules - Display") and specify the info structure you're interested in.
In the standard configuration, there are two update groups (easy: "1" and "2")
For each key figures, you can display "rules for characteristics" and "rules for key figures". It will help you undertand how data is updated, when, and where it comes from.

All info structures are part of the LIS (SPRO / Logistics General /
Logistics Information System)
try T-Code MC26 ("Mantain update rules - Display") and specify the info
structure you're interested in.
In the standard configuration, there are two update groups (easy: "1" and
"2")
For each key figures, you can display "rules for characteristics" and "rules
for key figures". It will help you undertand how data is updated, when, and

Hope this helps.
