|Is there a limit on the number of rows for the FKM's ignore key?
There is a maximum of 500 rows allowed by Gateway Setup Editor (GSE) to be displayed, but you can switch to XML mode in order to view more rows. This is to prevent any performance impact on the GSE, that is, to avoid the interface from slowing down too much. The limit is for the Gateway Setup Editor only; there is no actual limit in the Netprobe or Gateway.
If you have 500 rows and then try to add another, the GSE will tell you there is a limit of displayed rows. You can still add row when you switch to XML mode but those after the 500th will not be displayed when you switch back to normal mode.
This limit on the GSE is non-configurable for the user. As a workaround, you can create multiple FKM tables to manage more than 500 rows.
