Hi Victor
Would you please try the following steps:
1. Fun program UJ0_GET_GEN_TABNAME with Environment and Model ID.
2. Find the "Work Status Lock" table in the result of step1. (e.g./1CPMB/XXXX)
3. Check this table in SE11 and see if the status is "Active" or not.
4. If the status is not "Active", you can delete this table and then try activating the work status through BPC web client again.
Best regards,
Chuan
