The “Run a bulk share” button allows you to schedule a bulk share to run for this table. This can be useful for when you create a dynamic share and want to initially seed the subscriber (another instance or database) with the table's data.
Pressing this button will save the dynamic share and schedule a bulk share to be run. The bulk share will honor the dynamic share's configurations where relevant such as include journal fields, include attachments and filter conditions. The bulk share will be related to this dynamic share so you can see it in the dynamic share's related list.
If the dynamic share has the “Share base table only” option selected, the bulk share will unselect the “Include child only” option so that both are consistently sharing the same records (i.e. both are sharing child records only or sharing the selected base table only).
