you can simply set value of age from cdtB , like CDT A. Age = CDT b.Age in loop. so the final CDT will have all three fields with updated value

Hey Chandu,

I thought of DB View but don't you think it will become a long process?

Thanks Mohamed, It worked. I really appreciate your time and efforts. Thank you once again :)

Hi Vivek, Does DB View will not be good to suffice your requirement?

Try this ,

a!forEach(
items:ri!SeparatedData_CDT,
expression:{'type!{urn:com:appian:types}WebLaunchParameters'(
ProcessDataCaption: ri!SeparatedData_CDT[fv!index].ProcessDataCaption,
FieldIdentifier: ri!SeparatedData_CDT[fv!index].FieldIdentifier,
ProcessDataLaunch: ri!SeparatedData_CDT[fv!index].ProcessDataLaunch,
ProcessDataOptional: ri!SeparatedData_CDT[fv!index].ProcessDataOptional,
ProcessDataValue: index(ri!VD_Datasubset.ProcessDataValue,wherecontains(ri!SeparatedData_CDT[fv!index].FieldIdentifier,ri!VD_Datasubset.FieldIdentifier),""),
KeyFormAttributeType: ri!SeparatedData_CDT[fv!index].KeyFormAttributeType,
FormAttributeValue: ri!SeparatedData_CDT[fv!index].FormAttributeValue
)}
)

Can you paste the rule logic you have writen here.

RE: How to map CDT

viveku3486 — Tue, 09 Jan 2018 13:37:50 GMT

You mean one value at a time? I'm doing it like rule!MapManualValueToCDT(pv!firstCDT,pv!secondCDT) and then inside the rule i'm implementing your logic

mohamedt808 — Tue, 09 Jan 2018 13:32:10 GMT

I am guessing that while trying it you have given the whole CDT as first parameter for index function , try specifying the parameter needed with dot notation .

Hello Mohamed,

I tried your logic but its giving me error i.e Invalid index: Cannot index type Number (Integer) into type CDT2) (Data Outputs)

RE: How to map CDT

mohamedt808 — Tue, 09 Jan 2018 11:29:18 GMT

As per what you are saying, you can use a simple index function and store these value in the actual CDT.Lets Say variable "a" (DS_SeparatedData?list) and Variable "b" (VD_SeparatedData?list) then store the result of following in variable a.

a!forEach(
items:ri!a,
expression:{'type!{urn:com:appian:types}DS_SeparatedData'(
Datacaption:ri!a[fv!index].Datacaption,
KeyIdentifier:ri!a[fv!index].KeyIdentifier,
DataValue: index(ri!b.DataValue,wherecontains(ri!a[fv!index].FieldIdentifier,ri!b.FieldIdentifier),""),
FieldIdentifier:ri!a[fv!index].FieldIdentifier)}
)

Hey Alok,

I don't want to map the data between two different CDT's. I want to map data between two variables of same CDT. Here my variables are different but their CDT is same. for eg, CDT A is one variable of type 'Employee' and CDT B is another variable of same type 'Employee'. Only difference is the number of properties they hold. In this case lets say CDT 'Employee' have 3 fields than variable CDT A contains all the three columns and CDT B contains only two columns. So whatever will be the value inside variable CDT B, I want to make the changes in CDT A.

RE: How to map CDT

viveku3486 — Tue, 09 Jan 2018 10:57:35 GMT

Yes these two CDT's are multiple. Let me give a quick example

CDT A:[Name=abc,Age=,Gender=Male],[Name=pqr,Age=,Gender=Female],[Name=xyz,Age=,Gender=Male] and so on.

Similarly CDT B contains
CDT B:[Name=abc,Age:40],[Name=jkl,Age:60],[Name=xyz,Age:20]

As You can CDT A is my original CDT which contain all the columns whereas CDT B contains only 2 columns i.e Name and age. In CDT A you can see that "Age" property is blank. So what I need is that I need to update the values in CDT A with the matching values available in CDT B. My Final output would be something like

[Name=abc,Age=40,Gender=Male],[Name=pqr,Age={Blank as no record for "pqr" is available in CDT B},Gender=Female],[Name=xyz,Age=20,Gender=Male] and so on.

type!B is nothing but, will be used to form a the original variable. Let's say In your case actual cdt in which you want to copy the data, if its name is Employee then you could declare it as follows:

type!Employee(
empName: ri!otherCDT.empName,
email: "abc@test.com",
identifier: ri!otherCDT.eventIdentifier
)

Assume empName, email & identifier are the properties of your Target/Actual CDT where as empName, eventIdentifier is the property of your parameterized CDT which has the value

Here type!Employee() will prepare a CDT object of type Employee

Also, if you want to generate array of CDT then you need to make the use of looping functions such as: a!forEach(), apply() etc..

Hope this will help you.

Are these two CDT's multiple??

viveku3486 — Tue, 09 Jan 2018 10:30:53 GMT

Hey Alok,

How this logic will take effect a change in original variable? We are nowhere passing the original variable

viveku3486 — Tue, 09 Jan 2018 09:51:22 GMT

Let me try this between thanks for all your time and efforts.

RE: How to map CDT

aloks0189 — Tue, 09 Jan 2018 09:47:50 GMT

The parameter should be the CDT which is having the values, from which you want to copy the values to another CDT.

Let's say CDT A is having value which you want to copy into CDT B, then CDT A should be parameter and inside rule you use

type!B(
FieldIdentifier: ri!B.FieldIdentifier,
DataValue: something
)

I assume FieldIdentifier and DataValue along with other properties(optional) are the property of your CDT B

Hope this will help you

viveku3486 — Tue, 09 Jan 2018 09:38:56 GMT

Hey Alok, Thanks for quick reply. The parameter which I will pass in expression rule should be my original CDT or the one where updated values are stored? Can you refer the above mentioned variables and implement it in your logic? That will clarify my all doubts. Thanks in advance

RE: How to map CDT

aloks0189 — Tue, 09 Jan 2018 09:33:51 GMT

Hi for your requirement, you can create an expression rule, which will have your CDT as input parameter (which is having the value).

Now use type!yourCDT(
All property of your desired CDT: required value
)

Where type!yourCDT() is of your desired type CDT which you want to get as an output/response.

This should do your job.
