Data Slice Error in Locking Workbook in BW IP

Hi,

We have created locking mechanism of BW IP through a Workbook by calling a planning function/planning sequence.

Problem we are facing is unless you a User locks the planning function/sequence in a TR in BW then only he is able to execute from Workbook otherwise it throws an error.

So if I want to execute that workbook then I will have to save the embedded planning function of Workbook into a TR in BW and then I can execute the Workbook to call planning function.

if I don't lock the planning function in a TR,it throws a class error.

Anyone has any solution to this problem.

Thanks
