Open data slice for data entry and close afterwards

Question

Dear all,
I have created one data slice for a characteristic combination country xy in order to prevent the data entry within the data entry query for the user. But for some reason I have to run a planning function in order to summarize some values and write a total value in the characteristic e.g. country xy.
The planning function brings out an error message because this can not be executed due to the fact that this combination is protected.
Is there a way to open the data slice before the planning function is writing the data in the cube? I have tried to to this in the Data slice exit, but I do not have an idea how to open the DS, save the data and close the DS again.
We are running NW BI 7.0. Any ideas would be great.
Best regards,
Stefan from Munich/Germany

I did something like this by creating an FM and calling that FM from a FOX function. I think you will have to use three commands to execute three functions one after the other (and not combine them in one planning sequence) - first one will switch off the data slice, next will be your planning function containing the logic, and the last will switch it back on.
The FM would be something like below:
FUNCTION Z_SWITCH_DSLICE.
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(I_INFOPROV) TYPE  RSINFOPROV
*"     REFERENCE(I_DSNR) TYPE  RSPLS_DSNR
*"     REFERENCE(I_STATUS) TYPE  I
*** This function imports the name of a real-time Infoprovider and a Data Slice number
***        and a parameter I_STATUS. If I_STATUS is 1, data slice is activated
***        If I_STATUS is -1, data slice is de-activated
data wa_ds type rspls_ds.
select single * from rspls_ds
        into wa_ds
        where infoprov = I_INFOPROV
          AND objvers = 'A'
          AND dsnr = I_DSNR.
if I_status = 1.
   wa_ds-used = 'X'.
elseif I_status = -1.
   wa_ds-used = ''.
endif.
update rspls_ds from wa_ds.
ENDFUNCTION.
The Fox code will be like below -
CALL FUNCTION Z_SWITCH_DSLICE
    EXPORTING
       I_INFOPROV = <infoprov name>
       I_DSNR = <Data Slice Number>
       I_STATUS = <0 or 1>.
