Apply Data Slice Values while executing a Planning Folder

Hi all.

I already have a Function Module to Activate/Deactivate DataSlices depending sending parameters like area and sort (number of data slice).

My problem now is how to apply the new values of UPC_DATASLICE table while in execution of a planning folder.

As an example, suppose a user1 executes a folder. Then, after he's executed the folder, another user (an Administrator) activates a dataslice that locks some data... what I want is that the user1 doesn't write in the values selected by the dataslice even though he executed the planning folder before the activation of the dataslice.

Greetings.
