Hi Michael,
you do not need a bypass. you need to set the correct combination of lock characteristics in RSPLSE as Gregor already told you.
read a bit here:
Lock Concept and Lock Management - Planning Business Data with BW Integrated Planning - SAP Library
you need to define what selections the users should be able to work on in parallel.
Then use those char as the locking char
i.e. if users shall be able to work on the data for employees in parallel, the employee is lock relevant and user MUST do a selection on the eployees (or the users locks all employees).
regards
Cornelia
