Want to iterate CDT (list) and copy to the new CDT as MAP (like key(i.e. text),value (i.e. list of CDT)pair)

Hi Soujanya,
By analysing your cdt and data i am assuming that you want to set the details of WellList with associate AMU's
to do so first get the distinct AMUNames from the dictionary by using
distinct(index(cdt,"AMU",{}),index(cdt,"AMU",{})) by this you will get the distinct AMUNames
after getting distinct AMUNames do forEach,
follow the example code :
load(
local!distinctAMUNames: distinct(index(cdt,"AMU",{}),index(cdt,"AMU",{}))
forEach(
items: local!distinctAMUNames,
expression: with(
local!currentAMUs: fv!item,
type!RTRR_HOG_LEG_BY_AMU(
AMUNames :local!currentAMUs,
wellList: forEach(
items:index(yourCDT, wherecontains( local!currentAMUs,index(yourCDT,"AMU",{})),{}),
expression: type!WellList(
WellName : index(fv!item,"wellName",null),
UWI : index(fv!item,"wellName",null),
userList : /* Your code */
)
)
)
)

)
)

Thanks for you response!
I am in 16.3 apian version.I don't think we have foreach function is available in 16.3.

You can use apply function instead of forEach,
but the code may bit change, you need to create separate rules for constructing the CDT and iterate on that.
rule1
-------
load(
local!distinctAMUNames: union(index(cdt,"AMU",{}),index(cdt,"AMU",{}))
apply(
rule!construct_RTRR_HOG_LEG_BY_AMU_CDT(
AMU: _,
yourCDT : yourCDT ( pass whole data )
),
list : local!distinctAMUNames
)
)
rule2 (construct_RTRR_HOG_LEG_BY_AMU_CDT)
-------
type!RTRR_HOG_LEG_BY_AMU(
AMUNames :ri!AMU,
wellList:apply(
rule!constructWellList(
cdt:_
),
index(yourCDT, wherecontains( ri!AMU,index(yourCDT,"AMU",{})),{})
)
)
rule3 (rule!constructWellList)
---------
type!WellList(
WellName : index(ri!cdt,"wellName",null),
UWI : index(ri!cdt,"wellName",null),
userList : /* Your code */
)

Hi Tried with the same approach..
Child CDT (WellList) is not getting populated with the data.Getting empty results.Attached the rules.

Rule 1:
=========
load(
local!distinctAMUNames: union(
index(ri!totalwelllist,"AMU",{}),index(ri!totalwelllist,"AMU",{})),
apply(
rule!rtrr_construct_lge_by_amu(
"AMU": _,
"totallist" : ri!totalwelllist
),
local!distinctAMUNames
)
)

Rule 2
======

'type!{urn:com:appian:types}RTRR_HOG_LGE_BY_AMU'(
AMUName :ri!AMU,
wellList:apply(
rule!Rtrr_ConstructWellList(
cdt:_
),
index(ri!welllist, wherecontains(ri!AMU,index(ri!welllist,"AMU","")),{})
),
LGE : union(index(rule!get_RTRRHOBBusinessUsersbyAMU(index(ri!welllist,"AMU",null)),
"UserName",null),"")
)


Rule 3
====

'type!{urn:com:appian:types}WellList'(
WellName : index(ri!welllist,"WellName",null),
UWI : index(ri!welllist,"LicensedUWI",null)
)


OutPut which it results : Well List is not pupulating
======================================
[AMUName=Atmore, WellList=[WellName=, UWI=], LGE=Wesley Blake; Andy Olajide; Wesley Blake] :

In your third rule, ri!welllist has value?, if Yes try as below:

'type!{urn:com:appian:types}WellList'(
WellName : apply(index(_,"WellName",{}),{ri!welllist}),
UWI : apply(index(_,"LicensedUWI",{}),{ri!welllist})
)

I know apply is use for multiple however sometimes index function does not respond if CDT structure is not proper.

Soujanya B just confirm that below code
index(ri!welllist, wherecontains(ri!AMU,index(ri!welllist,"AMU",{})),{})
is returning you the correct result.

Yes it is returning correct result

Soujanya, did you tried the below code?

I have tried this , but no luck

I have tried this , but no luck

So you are saying that your ri!welllist has values, can you check the return type. It should be your CDT type.
