Datasubset

HI ,
I am trying to update a process variable of type datasubset,
I am using the following code to update a particular index value,

a!update(
 data: pv!dataSubset,
 index: index(
   index(
     pv!dataSubset.data,
     wherecontains(
       1,
       tointeger(
         index(pv!dataSubset.data, "verse_no", {})
       )
     ),
     {}
   ),
   "sentOn",
   {}
 ),
 value: now()
)

As the data is an array and at each index again is a CDT.
And I am trying to store it in the PV(type Datasubset) but I could not able to do it I am getting an error "(Expression evaluation error at function a!update: Invalid index: Cannot use multiple numeric indices into record for update) (Data Outputs)"

Your index function at line 3 must be returning multiple indexes. Anyway, the index function is not providing you a number or a property rather it will provide you the value of "sentOn" which is not the correct index that can be passed in a!update()

In this case, I recommend to use a foreach loop to iterate on the items. If the item matches your condition, update it, else, return the unmodified item.
