Refresh PartBin QOH from parttran

Would like to ask concerning the follow menu item: Refresh PartBin QOH from PartTran.

We would like to know more on the function, the purpose of this, when should we use this, and the impact of this if we were to run this report.

Last week, we encountered an issue where there is a discrepancy between PartBin and warehouse on hand quantity, and tried running this report, but it affected various other modules, users were unable to perform inventory movement, quantity adjust, etc. (related to inventory movement).
