Array property indexing and update

If installing the plugin is not an option, then I would suggest one of the following:
1. Simply save values using a!save(local!rowData.ppiStatus, "Void") for each selected row
2. namk's explanation of using the type! constructor

This is all assuming there are not going to be a huge number of selected rows to which applying over them would be a performance concern.

Also, i am using 18.1 since i am missing plug-in that is perhaps why i do not see any documentation either.

Aah, i do not have the updatecdt plug in installed in the cloud env, i am using. Is there a way around to updatecdt ?

You may not even need the a!forEach() since updatecdt seems to take a list of CDTs as a parameter.

Once you have local!rowData as your cdt values, you can simply do the following:

a!forEach(items: local!rowData, expression: updatecdt(cdt: cons!APP_CDT, fieldsAndValues: {ppiStatus: "Void"}))

The way i have it is: a!save(local!Rowdata,
index(local!ticketInfo.data,wherecontains(
local!gridSelection.selected,
local!ticketInfo.identifiers
),{}
)
)

So local!Rowdata has only the selected records from the editable. Now I want to go to each record and set the status field to void. I was hoping to find the index of the value that i get by doing: index(local!rowdata,"ppiStatus"} and then somehow use updatearray to replace the status value with "void". Then submit local!Rowdata using WrtToDS. Hoping my approach is correct.

It looks like the updatecdt() function would be helpful for your use case. You would set the fieldsAndValues parameters to include all of the fields you'd like to update. For example: {ppiStatus: "Void", modifiedBy: loggedInUser()} etc.

Have you looked at casting it with a rule? for example:

cast(
'type!{urn:com:appian:ZOO}ZOO_pens',
{
id: if(isnull(ri!id), ri!pen.id, ri!id),
name: if(isnull(ri!name), ri!pen.name, ri!name),
photoId: if(isnull(ri!photoId), ri!pen.photoId, ri!photoId),
dateAdded: if(isnull(ri!dateAdded), ri!pen.dateAdded, ri!dateAdded),
addedBy: if(isnull(ri!addedBy), ri!pen.addedBy, ri!addedBy),
status: if(isnull(ri!status), ri!pen.status, ri!status),
type: if(isnull(ri!type), ri!pen.type, ri!type),
isInactive: if(isnull(ri!isInactive), ri!pen.isInactive, ri!isInactive),
inRepair: if(isnull(ri!inRepair), ri!pen.inRepair, ri!inRepair)
}
)

You can then call this on your expression rule in an a!save, where you update the array with the expression. You can pass in the whole array, and also specify named variables so that those are updated properly. You can then call the WriteToDS function to save the array.
