Order of Processing in I_STEP=2

Hi all

Does anyone know how to change the processing order for the Variable User Exit during I_STEP=2? I have 4 variables in my query of which 2 are hidden and populated in the Exit.

The variables are:

Calendar Year/Month

Org Unit

KeyDate

Employee

I want to derive the KeyDate first based on the Calendar Year/Month. I then want to derive a list of Employees based on KeyDate and OrgUnit (this is for authorisations).

When I run the query in debug mode (RSRT) the Employee variable is always processed before the Key Date.

Any help would be appreciated.

Thanks
