how can i add two interfaces in one summary view

What is your question?

I want to call two different Dashboards in one summary view

{
  rule!NZP_DASH_MaintenanceSummaryView(maintenance: rv!record),
  rule!NZP_DASH_MaintenanceSummaryViewForPen(maintenance: rv!record)
}

actually, i want to call those interfaces in one summary view either this or that

if(
'recordType!{3a147a0e-d35e-4fa0-96f7-d91590fdf68d}NZP Maintenance.fields.{b3c7019a-c216-42e6-b725-b7c67abec412}requestType'="Medical",
rule!NZP_DASH_MaintenanceSummaryView(maintenance: rv!record),
rule!NZP_DASH_MaintenanceSummaryViewForPen(maintenance: rv!record)
)

OK. But then, what is your question. It seems like you are already doing what you want to achieve ?!?

I am confused. Please help me to understand your specific situation.

i cant able to call those interfaces in one summary it seems that its not able to work

its my site when iam selecting the medical request like option 1 its showing me the pen dashboard this dashboard

rule!NZP_DASH_MaintenanceSummaryViewForPen(maintenance: rv!record)

but i want this dashboard to show 

rule!NZP_DASH_MaintenanceSummaryView(maintenance: rv!record),

I don't understand. Do you see any error messages? Does your condition in the if() not work?

yaahh exactly

Well, then, what is the actual value in that "requestType" field? 

1]Medical for animal

2]Equipment for pen

You do not reference that field in the record to compare the value, but compare the name of the record field itself against that literal.

Change it to

ri!maintenance['recordType!{3a147a0e-d35e-4fa0-96f7-d91590fdf68d}NZP Maintenance.fields.{b3c7019a-c216-42e6-b725-b7c67abec412}requestType']

Find the documentation here: docs.appian.com/.../reference-records.html

it is not working

What is not working? More details please !!!

its my interfaces

these two interfaces i want to call this in one maintenance summary view but iam getting only one interface for different types

Not sure why you share this with me.

You explained that the actual issue is with the if() statement. Then I suggested changing that code, but there still seems to be a problem with that if().

Can you share the current state of that if()?
