Hi,
As suggested by KertLuo Virtual Table Server will be a good option in your case.
Please review the available functions in the Virtual Table Server (VTS) Functions (VTC) > Virtual Table Server (VTS) Functions for Multiple Connections (vtc)
You have functions for saving data for example:
1. vtc_send_if_unique which sets the last field of a column to a value if the value does not exist in the column and
2. vtc_send_message - sets the last field of a column to a value.
After saving the values during replay each Vuser can get a value from the table in the VTC and delete it so that it will not be available for the next Vuser using
vtc_retrieve_message funcition which pops the first field from a column.
Kind regards,
