Expression rule

Hi Vamsi

Firstly, for future reference, please use the "Insert Code" option to include code in your posts as it makes it way easier to read/copy/paste for those of us who are trying to help:

Secondly: the code doesn't look well-formed to me. Pasting it into the Expression Editor it throws a syntax error:

if(rule!AF_RULE_General_isBlank(wherecontains(cons!GCC_DSE_cons_getReadOnlyDrillStatus,tointeger(local!drill.drillStatus))),
remove(local! facilityFloors, wherecontains (false,local! facilityFloors.isActive)),
if(not(rule!AF_RULE_General_isBlank(local!drillfacilityFloors)),
local! drillfacilityFloors,
remove(local!facilityFloors, wherecontains (false,local!facilityFloors.isActive))))

if(rule!AF_RULE_General_isBlank(wherecontains(cons!GCC_DSE_cons_getReadOnlyDrillStatus,tointeger(local!drill.drillStatus))),
remove(local! facilityFloors, wherecontains (false,local! facilityFloors.isActive)),
if(not(rule!AF_RULE_General_isBlank(local!drillfacilityFloors)),
local! drillfacilityFloors,
remove(local!facilityFloors, wherecontains (false,local!facilityFloors.isActive))))

Same code, same syntax error

Expression evaluation error: Syntax error. Details: Cannot create an identifier with zero length key:

...that is, this code will never work as it stands.

I think spacing is an issue here.

I reformatted the code as follows and added some notes.

Basically it's using a combination of wherecontains which Receives one or more values and returns an array of indices that indicate the position of the values within the array and removes those values

if(
  /* Checks if local!drillStatus has any values listed from the cons!GCC_DSE_cons_getReadOnlyDrillStatus*/
  rule!AF_RULE_General_isBlank(
    wherecontains(
      cons!GCC_DSE_cons_getReadOnlyDrillStatus,
      tointeger(local!drill.drillStatus)
    )
  ),
  /* If yes (from line 2) then, finds all indexes of items which have local!facilityFloor.isActive = false()
  and removes them from local!facilityFloors*/
  remove(
    local!facilityFloors,
    wherecontains(false, local!facilityFloors.isActive)
  ),
  /* If no (from line 2)*/
  if(    
    not(
      rule!AF_RULE_General_isBlank(local!drillfacilityFloors)
    ),
    /* If local!drillFacilityFloors has any value (not empty), retrun it */
    local!drillfacilityFloors,
    /* Else, finds all indexes of items which have local!facilityFloor.isActive = false()
    and removes them from local!facilityFloors */
    remove(
      local!facilityFloors,
      wherecontains(false, local!facilityFloors.isActive)
    )
  )
)

Thank you very much Hrishikesh Dixit  for ur time and the answer.
