Not able to change the prefix in number maintenance table

[PoorvaB]

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

That approach doesn’t seem correct, @PoorvaB 

We need to recognize that the two tables serve entirely different purposes. Using the same prefix for both will only lead to confusion, which is likely the root cause of the issue here. To avoid this, it’s better to assign separate prefixes to each table to maintain clarity and prevent errors.
