Steps to Calculate Fields in Work Class and Data Class 1. **Identify the Classes and Fields** - Determine the work class (e.g., `Work-MyWorkClass`) and data class (e.g., `Data-MyDataClass`) involved. - Identify the fields in these classes that you want to use in your calculation. 2. **Create or Edit a Data Transform** - In the work class or a relevant data class, create or edit a data transform to perform the calculation. - In the data transform, use the `Set` action to define and calculate the fields. 3. **Referencing Data Class Fields in Work Class** - Use a Page property in the work class to refer to an instance of the data class. - For example, if your work class has a page property `.DataPage` of type `Data-MyDataClass`, you can reference fields in the data class using `.DataPage.FieldName`. 4. **Perform the Calculation** - Within the data transform, perform the calculation using the referenced fields. - Example: Set `.CalculatedField` = `.WorkField + .DataPage.DataField`. Example Data Transform Steps: 1. Set `MyDataPage` to reference the data class instance. - Action: Set - Target: `MyDataPage` - Relation: `=` (equal to) - Source: `D_GetDataPage[Primary.ID]` (assuming a data page that fetches the data class instance based on an ID from the work class) 2. Perform the calculation. - Action: Set - Target: `.CalculatedField` - Relation: `=` (equal to) - Source: `.WorkField + .MyDataPage.DataField` Example of a Data Transform in Work Class ```plaintext Step 1: Action: Set Target: MyDataPage Relation: = Source: D_GetDataPage[Primary.ID] Step 2: Action: Set Target: .CalculatedField Relation: = Source: .WorkField + .MyDataPage.DataField ``` Using Activities Alternatively, you can use activities to perform these calculations, but it is generally recommended to use data transforms for maintainability and simplicity. Example of an Activity 1. Create an activity in the work class. 2. Add steps to set the page properties and perform the calculation. ```plaintext Step 1: Method: Page-New Step Page: MyDataPage Class: Data-MyDataClass Step 2: Method: Property-Set Step Page: MyDataPage Properties: - DataField (assign the value from a data source or calculation) Step 3: Method: Property-Set Properties: - CalculatedField = WorkField + MyDataPage.DataField ``` Using Declare Expressions Declare expressions allow for automatic calculation when the relevant properties change. 1. Create a declare expression in the work class. 2. Define the expression to calculate the value using fields from both the work class and the data class. Example of a Declare Expression - Target Property: `.CalculatedField` - Expression: `.WorkField + .DataPage.DataField` Summary 1. Identify the relevant work class and data class fields. 2. Use data transforms, activities, or declare expressions to perform the calculations. 3. Ensure proper referencing of data class fields within the work class.

@@HarshaTrainingsacademy Thanks for the reply... Sure will do!
Hi Harsha,
Can you do video on Active MQ configuration for JNdi server
Hi Gopi sure will try to do it
Are we do person details in Organization Level Data class.and why you choosen application level( Bajaj-Data-Person)
Hi Brahma the reason is , person class is very common across entire application
Personal pega training will be done ?please reply

How to calculate the field in work class and data class(combination)?
Steps to Calculate Fields in Work Class and Data Class
1. **Identify the Classes and Fields**
- Determine the work class (e.g., `Work-MyWorkClass`) and data class (e.g., `Data-MyDataClass`) involved.
- Identify the fields in these classes that you want to use in your calculation.
2. **Create or Edit a Data Transform**
- In the work class or a relevant data class, create or edit a data transform to perform the calculation.
- In the data transform, use the `Set` action to define and calculate the fields.
3. **Referencing Data Class Fields in Work Class**
- Use a Page property in the work class to refer to an instance of the data class.
- For example, if your work class has a page property `.DataPage` of type `Data-MyDataClass`, you can reference fields in the data class using `.DataPage.FieldName`.
4. **Perform the Calculation**
- Within the data transform, perform the calculation using the referenced fields.
- Example: Set `.CalculatedField` = `.WorkField + .DataPage.DataField`.
Example Data Transform Steps:
1. Set `MyDataPage` to reference the data class instance.
- Action: Set
- Target: `MyDataPage`
- Relation: `=` (equal to)
- Source: `D_GetDataPage[Primary.ID]` (assuming a data page that fetches the data class instance based on an ID from the work class)
2. Perform the calculation.
- Action: Set
- Target: `.CalculatedField`
- Relation: `=` (equal to)
- Source: `.WorkField + .MyDataPage.DataField`
Example of a Data Transform in Work Class
```plaintext
Step 1:
Action: Set
Target: MyDataPage
Relation: =
Source: D_GetDataPage[Primary.ID]
Step 2:
Action: Set
Target: .CalculatedField
Relation: =
Source: .WorkField + .MyDataPage.DataField
```
Using Activities
Alternatively, you can use activities to perform these calculations, but it is generally recommended to use data transforms for maintainability and simplicity.
Example of an Activity
1. Create an activity in the work class.
2. Add steps to set the page properties and perform the calculation.
```plaintext
Step 1:
Method: Page-New
Step Page: MyDataPage
Class: Data-MyDataClass
Step 2:
Method: Property-Set
Step Page: MyDataPage
Properties:
- DataField (assign the value from a data source or calculation)
Step 3:
Method: Property-Set
Properties:
- CalculatedField = WorkField + MyDataPage.DataField
```
Using Declare Expressions
Declare expressions allow for automatic calculation when the relevant properties change.
1. Create a declare expression in the work class.
2. Define the expression to calculate the value using fields from both the work class and the data class.
Example of a Declare Expression
- Target Property: `.CalculatedField`
- Expression: `.WorkField + .DataPage.DataField`
Summary
1. Identify the relevant work class and data class fields.
2. Use data transforms, activities, or declare expressions to perform the calculations.
3. Ensure proper referencing of data class fields within the work class.

Tq Harsha for the immediate response
I am anable to understand it, could you plz tell me in another way
Hii Harsha, Can I know why you chosen data class as concrete class
Hi Brahma, some times we may have to store the instances into this data classes. that why we choose it to be concrete class..
