Since you are using picker, you should not be able to select same user multiple times

What is value in

local!taskAdditionalAssignee and

ri!record['recordType!{a6f5f29e-a89e-495a-afae-702df167aa19}RECT Record Tasks Sync.fields.{d0fec037-4f71-4d05-a7ef-766635d0ff13}taskAssignedTo']

still not throwing any validations-

validations: {
if(
and(
a!isNotNullOrEmpty(local!taskAdditionalAssignee),
a!isNotNullOrEmpty(local!taskAssignee),
contains(
local!taskAdditionalAssignee,
touser(ri!record['recordType!{a6f5f29e-a89e-495a-afae-702df167aa19}RECT Record Tasks Sync.fields.{d0fec037-4f71-4d05-a7ef-766635d0ff13}taskAssignedTo'])
)),
"Assignee cannot be added as additional assignee",
null
),

}

I tried wrapping up of both with touser

is there any way we can convert text type to user type?

RE: How to put validation on pickerfieldusers which can select max 5 users

appian.user — Thu, 10 Oct 2024 14:44:42 GMT

not throwing any validation now-

validations: {
if(
and(
a!isNotNullOrEmpty(local!taskAdditionalAssignee),
a!isNotNullOrEmpty(local!taskAssignee),
contains(
touniformstring(local!taskAdditionalAssignee),
touniformstring(ri!record['recordType!{a6f5f29e-a89e-495a-afae-702df167aa19}RECT Record Tasks Sync.fields.{d0fec037-4f71-4d05-a7ef-766635d0ff13}taskAssignedTo'])
)),
"Assignee cannot be added as additional assignee",
null
),

}

Soma — Thu, 10 Oct 2024 14:41:06 GMT

Try wrapping both variables that you are comparing with touniformstring()

local!taskAdditionalAssignee as user type and

(ri!record['recordType!{a6f5f29e-a89e-495a-afae-702df167aa19}RECT Record Tasks Sync.fields.{d0fec037-4f71-4d05-a7ef-766635d0ff13}taskAssignedTo']) as text

Use a local variable to store all the selected users as a list. When you write to record, use joinarray(localVariable,",")

When you load the value from record use

local!taskAdditionalAssignee: split(ri!record[recordField],",")

appian.user — Thu, 10 Oct 2024 08:54:22 GMT

Can you please suggest how should I take new variable and store it as additional assignee as I have store in this way which is not correct

RE: How to put validation on pickerfieldusers which can select max 5 users

Soma — Thu, 10 Oct 2024 08:27:42 GMT

Use the variable to store the list of user selected in comma separated values.

Use joinarray() while storing and use split() while bring it back inside Appian.

It will be stored like userA,userB,userC,userD,userE

After splitting it will list of 5 text

field is already added in existing recordtype type and databse as well as additionalassignee wihich is text type but it h

but it has to hold max 5 user when selecting from pickerfieldusers

RE: How to put validation on pickerfieldusers which can select max 5 users

Soma — Thu, 10 Oct 2024 08:01:28 GMT

I would advise you to create a new record called additionalAssignees, which will have one to many relationship with the existing record

RE: How to put validation on pickerfieldusers which can select max 5 users

appian.user — Thu, 10 Oct 2024 07:59:32 GMT

is it possible that we can exclude the user in B which is already selected in A?

appian.user — Thu, 10 Oct 2024 07:55:04 GMT

thankyou for your responce but still it is not fullfilling the requirement and i have 1 more question -

If I have to choose max 5 user from pickerfielduser then at backened level what should be data type for that particular field as in my case data type is text and I m using recordtype to store data

for reference: this field should hold atleast 5 user after submiting

Yogi Patel — Thu, 10 Oct 2024 06:29:33 GMT

It's better not to show the previously selected user(user selected in pickerFieldUsers field A) in the second pickerFieldUsers field (i.e. B).

RE: How to put validation on pickerfieldusers which can select max 5 users

Soma — Thu, 10 Oct 2024 06:14:43 GMT

Try including null check of the two variables

if(
  and(
    a!isNotNullOrEmpty(local!taskAdditionalAssignee),
    a!isNotNullOrEmpty(local!usersOfPickerB),
    contains(
      local!taskAdditionalAssignee,
      ri!record['recordType!{a6f5f29e-a89e-495a-afae-702df167aa19}.fields.{d0fec037-4f71-4d05-a7ef-766635d0ff13}']
    )
  ),
  "Assignee cannot be added as additional assignee",
  null
)
