BPC 10.0 SP20 : IC data and Flow dimension

Hi BPC experts,

When I run an IC Data package, the original flow data are all converted into an opening flow (called F_OB in my case).

Here is my logic script, where the FLOW F_TOT is the parent of F_OB and other flow (such as F_DEP - depreciation, etc.):

Now the issue :

I would like to keep the flows as they are in the original data. IC Data converts every flow into F_OB, which is not what I want. Is it possible to keep the flows as they are in the beginning ?

Thank you in advance,

Dat
