Serial number based on different initial codes upon user

[Mantenimiento_S]

Hello everyone. First of all I want to thank you for your help. 
I have a field where I write down a consecutive serial number. 
For each user this serial number starts with a different number. Example:
User 1: 242501001
User 2: 242502001
User 3: 242503001
How can I do so that, depending on the user and their specific serial number, I can add a consecutive number?
For example:
242501001 +1
242502001 +1
Thanks in advance

Hi, 

you can test

max(users[serial])+1000

One method:

1. Directly into the Initial Value field of the key column:

SWITCH(
  USEREMAIL(),
  "USEREMAIL@1.COM", 24250100 + (YourSerialExpressionHere),
  "USEREMAIL@2.COM", 24250200 + (YourSerialExpressionHere),
  "USEREMAIL@3.COM", 24250300 + (YourSerialExpressionHere),
  24260000 + (DefaultSerialExpression) ## This is an example, change it to fit your use case
)

Hi. Thank you very much for your question. I have a question. If a user with 3 records for example, 242501001, 242501002, 242501003, etc... hoy can I get the last record of each user to add 1 more number to be correlative?.

Thanks in advance.

This?

(
  MAX(
    SELECT(
      table[serial-number],
      (USEREMAIL() = [email])
    )
    + LIST(initial-number - 1)
  )
  + 1
)

Replace table, serial-number, email, and initial-number as appropriate.

2. Using a User table + each table has a user_email or similar field + the User table has a key value = to the user email:

[user_email].[key_range] + (YourSerialExpressionHere)
# Assuming you have a [key_range] field in which you assign the corresponding
# number base, like 24250100, 24250200, 24250300
