Please note that I didn't have TSS influent flow data and there is hanging outgoing variable (X_TSS), I didn't know what to do with it.

That's indeed the problem. And I am actually surprised you could go through the influent tool (and generate the influent model successfully).
You may not have an actual measurement of the TSS in your influent, but, being [b]X_TSS[/b] a [b]component of ASM2[/b], you are to provide a value (in fact, a time series) for it in the influent file.
This is not different to any other components of the component vector (the green blocks in the fractionation layout).
In fact, this is precisely what the [b]fractionation model[/b] is all about: by using your measurements, combined with a set of fractionation parameters and perhaps realistic assumptions, one describes the influent according to the specific ASM- component vector.
I see you have measurements for both soluble- and particulate COD.
You could derive X_TSS from the measured particulate COD; or a the sum (weighted!) of the components that contribute to TSS, i.e. X_I, X_S, X_H, X_AUT, X_PAO, etc.
