'BAPI_OBJCL_CHANGE' updates the database partially.

Hi

We are using 'BAPI_OBJCL_CHANGE' in a program running in batch at night.

Although we use SET UPDATE TASK LOCAL before the BAPI call and 'BAPI_TRANSACTION_COMMIT' with wait = 'X' after every BAPI call, the update is carried out only partially. Some records (randomly) are not updated, no error from BAPI in these records and if we run the program again some of these records will be updated.

Dose anybody know how to resolve this problem?

Any help will be appreciated.
