Error writing to MaxRecords: Bad_ReadOnly

I am trying to write Max records of store and forwards value from designer and getting error as It is ReadOnly,
How I can make this tag Read and Write.

This is a configuration value in the gateway, and can only be changed there (gateway web interface) by an admin user. The tags in the System provider are informational. (I don't think any of them are writable.)

Yes I can update directly on gateway however I am trying to write the tags with system.tag.writeBinding.

And you cannot. It is an informational tag. :man_shrugging:
