Passing BEx Variables from a Data Source into a Planning Sequence in Design Studio

Hello everybody,

we're building a BW-IP planning application using Design Studio 16.0.5.

In Design Studio I have a data source "DS_1" that contains a BEx variable "FMV_P_VERSION_1". Next I want to call a planning sequence "PS_1" and need to pass the BEx variable into the planning sequence. I tried (besides numerous other possibilities ...) both of the following scripts

    PS_1.copyVariableValue(DS_1, "FMV_P_VERSION_1");

    PS_1.execute();

and

    PS_1.setVariableValueExt("FMV_P_VERSION_1", DS_1.getVariableValueExt("FMV_P_VERSION_1"));

    PS_1.execute();

Both do not work.

In the planning sequence, I'm accessing the variable in a filter and in a FOX formula (with the statement "V = VARV(FMV_P_VERSION_1)."). The variable gets passed OK into the FOX formula, but as soon as I'm using it in the filter I get the error message "Einen Wert für Variable Version eingeben".

I need the variable in the filter to achieve correct locking behaviour.

Thanks for any suggestions how to work around this issue
