Hi, i am trying to fetch user/group name from a group name constant which c

Can you add your code and sample data of what the constant holds?

my constant namely XYZ is an array type holding user or group member type and then i have a process variable which is also group type and when i retrieve XYZ[1], instead of getting the full name i just get first name

XYZ is a multiple user or group variable. XYZ[index] would give the Appian username if the returned value is a user or the group id if the returned value is a group. You can use Appian user() function to retrieve First name and Last name from the returned username.

First, ensure you have defined the constant as multiple and the values are separated by a semi-colon. Secondly, use the INDEX function instead of the [] notation. This is a fail safe to avoid errors when data doesnt exist in a particular index or if the value of the array is null. Finally, when you are having a variable which is an array of User OR Group, you need to use the typeOf function to find out what type it is (for e.g. User is type 4) and once you know the datatype of the data you're retrieved, you can perform actions on it, such as fetching the first name etc.,

@sathya : i want to fetch the entire name , but i am getting only the first name . How can i get the entire name

Please look at the user() function in Appian Documentation.
Once you have a user object, you can obtain the full name (assuming first name + surname) by querying & concatenating the following attributes
CONCAT(user(pv!user, "firstName") ," ",user(pv!user,"lastName"))

The first name you mentioned you're getting might simply be the user's log-in name in your previous use case.

Hi Himanshu,

Please try below code:

if(runtimetypeof(cons!USER_OR_GROUP[2])=4,
concat(user(touser(cons!USER_OR_GROUP[1]),"firstName"),
" ",
user(touser(cons!USER_OR_GROUP[2]),"lastName")),
group(togroup(cons!USER_OR_GROUP[2]),"groupName"))


Here, the constant USER_OR_GROUP contains both user and groups, and its data type is user or group.

Hi Himanshug,

Below code try it once,
load(
local!user:cons!BA_CONSTANT_OF_USERNAME,
a!richTextDisplayField(
value: a!richTextItem(
text:
a!forEach(
items: local!user,
expression:
concat(user(username:fv!item,property:"firstName")," ",user(username:fv!item,property:"lastName"))
)
)
)
)

Hi Himanshu,

First you need to find particular value would be group or user
--Use runtimetypeof() function to find
If user then use user() function and fetch using properties like "firstName" , "lastName"
else value would be group.

Note: use toUser() and toGroup() to convert.
