Error while trying to modify a discriminator number

[enio.eltz]

Hi

I needed to do some changes in a discriminator rule to improve it. I created a new numbering discriminator table #51 and created my prefixes there. After this, I changed in the entity to use this new discriminator while I configured the new prefixes in the numbering discriminator #1, because after all I want the system uses numbering discriminator #1.
I created some prefixes in the numbering discriminator #1, but I needed to change a rule, now I get an error:

Press CANCEL to remove this window

processing Failure
OBJECT -1: Call Number: Undefined number

I couldn't reset the system yet, but I will do. Any advice is useful.

Thank you very much.

Hi

It solved with CS reset. Table blocked.
