How to lock with Dataslice by exit

Question

Hello,
BPS system release : 3.1B
I need to know how lock data with dataslice by using a exit function.
I created two exit function to a activate end deactivate a dataslice and a copy function to put may data in a validation status.
Execution order :
- deactivate dataslice
- copy function to put data in
- activate dataslice
When I tested those functions in previous order, in my planning level, my copy function doesn't work.It works only when I save model, leave BPS0 transaction, reload BPS0 transaction and, now the copy function is possible.
Objective:
  Put these functions into a planning sequence to lock data.
Does my problem due to
- SEM release?
- a missing function to save model or check to permit copy function?
- or else ?
Thank you for your help.

Hi Ulrich,
I assume your exit changes only the inactive flag in table UPC_DATASLICE.
The system buffers the state of the dataslices in memory when you go into BPS. Therefore your exit has no effect.
I suggest to use a user-specific or exit variable in the dataslice instead. This way you can allow changes by certain users while data is locked for others.
