Not able to change the prefix in number maintenance table

[Community Alums]

Hi Community,

I am not able to change the prefix of a custom table in number maintenance table. I am getting this error 'Error Message: The prefix EWM collides with the prefix of an existing record'.

When i am checking in the table, there is no record with the current prefix then why i am not able to change it?

Please let me know how to change it?

Thanks

Hi @Community Alums 

Did you have any record which start with EWM in system?

I have another custom table with the same prefix.

[Dr Atul G- LNG]

so you cant use same prefix again.
