When we open library member form then LM00001 should be shown in that field name automatically

On Creation of “member” you have serial number as default change to Name.

Thank you for reply .
I want to update the naming series [LM00001] in the existing doctype .That should be get updated in the another field when i save the form

  1. On the doc type you need to first populate “Naming” Field to either ‘name’ or ‘full name’ … this is for new members.
  2. You Can Try “Rename” , so click on “LM00001” and rename it to the name you want, this is for existing.

I want to update a another field in the same doctype with naming series . i.e LMOOO1 Should be shown in another field when it’s save

You mean to say that whatever the naming series is there that same should be fetch in the field name?

yes
when i save it
that LM0001 show in the field

Is the FieldName a custom field? Can you share the screenshot of your Library member doctype?

i want to store the LM00001 inside the fieldName
