I’m not aware of where this quantity can be seen inside the application but…
If you know where is such place, go there and just before loading data turn on trace log. It should give you an idea which BO and method is used to retrieve data that contains your value. In some rare situations you may not see everything in trace logs. Then you should check server logs to find it. I hope that helps.
No, this is the peak of laziness, but I’ll just live without it.
Out of 7,648 rows of PartBin in the applicable warehouse, there are 2 with allocations. That’s 1/40th of 1% . (Other warehouses do allocate, but this project is not for them.)
I’ll just do the math on the OH qty and be done with it. 99.97% accuracy is just fine.
