extract collection from json based on a condition using logic app - json

Question

I am trying to Extract and sum a particular value using group by from json collection in azure logic app. Trying to achieve this by applying "Condition" connector. My Json file looks like below:
"Release": [
{
"O_Id": "D_13211175",
"R_ID": "D_132111751",
"Res": [
{
"A_Id": "32323222",
"F_Qty": 1,
"I_Id": "828929",
"OL_Id": "1",
"Qty": 1,
"RL_Id": "1",
"Unique_Identifier": "5970703818904601622__1",
},
{
"A_Id": "32323223",
"F_Qty": 1,
"I_Id": "828929",
"OL_Id": "1",
"Qty": 1,
"RL_Id": "1",
"Unique_Identifier": "5970703818904692717__1",
},
]
}
]
I want to calculate the sum of Qty group by I_Id from array Res using logic app connector "Condition".
Note: As Res is an array, there can be repetition I_Id with same value, hence, the requirement to get the Qty count based on I_Id

Answer 1

There are few ways to achieve your requirement but here is one of the workaround that worked when reproduced from our end.
Firstly, I have initialised a temporary integer variable to iterated inside the "Res" Array using Until Loop by checking the length of "Res" using the below expression.
length(body('Parse_JSON')?['Release']?[0]?['Res'])
Inside Until I have used condition action to check if I_Id is same using the below expression to the left.
body('Parse_JSON')?['Release']?[0]?['Res']?[variables('temp')]?['I_Id']
and below expression to the right
body('Parse_JSON')?['Release']?[0]?['Res']?[add(variables('temp'),1)]?['I_Id']
Then if the condition satisfies I'm adding the Qty using the expression as below.
add(body('Parse_JSON')?['Release']?[0]?['Res']?[variables('temp')]?['Qty'],body('Parse_JSON')?['Release']?[0]?['Res']?[add(variables('temp'),1)]?['Qty'])
Here is the flow of my logic app
[Optional step]
Considering the bigger picture, I have initialzed another variable quantity and added the resultant of Compose 4 to Qty variable
RESULTS:
Considering the below sample JSON
{
"Release": [
{
"O_Id": "D_13211175",
"R_ID": "D_132111751",
"Res": [
{
"A_Id": "32323222",
"F_Qty": 1,
"I_Id": "828929",
"OL_Id": "1",
"Qty": 1,
"RL_Id": "1",
"Unique_Identifier": "5970703818904601622__1"
},
{
"A_Id": "32323223",
"F_Qty": 1,
"I_Id": "828929",
"OL_Id": "1",
"Qty": 1,
"RL_Id": "1",
"Unique_Identifier": "5970703818904692717__1"
},
{
"A_Id": "32323223",
"F_Qty": 1,
"I_Id": "828929",
"OL_Id": "1",
"Qty": 5,
"RL_Id": "1",
"Unique_Identifier": "5970703818904692717__1"
}
]
}
]
}
Here is the result
