Extends a table issue

[Sarah Bouil]

Table A -> 2 Fields Table A5 and Table A1 etc

Table D-> 2 Fields Table D1 and Table D2

Table D is extended from Table A

So if I create a record in Table D, the record is creating in Table A and Table A5 field is increasing? Table A5 is a Number Maintenance, but Table A5 should not increase when I create Table D record right

Hello @Sarah Bouil 

Please go to sys_number [Number maintenance] table. Find the record for Table A5 and check if "Applies to all child tables" is enabled. If it is please disable that. 

Additionally since , you have inherited table D from Table A, all the fields which are Table A will automatically come in Table D. 

Please mark my answer as helpful and accept solution if it helped you in anyway.

Yes, in ServiceNow, a record created in an extended table will also create a corresponding record on the parent table. This is because the extended table inherits fields and properties from the parent table
