Mastering PeopleSoft Technical Development: Common Challenges and Step-by-Step Solutions

 

PeopleSoft technical development can be tricky, especially for beginners or those transitioning from other ERP systems. Many developers struggle with PeopleCode, SQL, Application Engine, and debugging complex issues. In this blog, we’ll break down some of the most common challenges and provide step-by-step coding solutions in an easy-to-understand way.

1. How to Loop Through a Rowset in PeopleCode

Problem: Many developers struggle with iterating through rowsets efficiently.

Solution: Use the GetRow and GetRecord functions.

Local Rowset &rs;
Local number &i;

&rs = GetLevel0()(1).GetRowset(Scroll.EMPLOYEES);

For &i = 1 To &rs.ActiveRowCount
    &rec = &rs.GetRow(&i).GetRecord(Record.EMPLOYEES);
    &name = &rec.GetField(Field.EMPL_NAME).Value;
    MessageBox(0, "", 0, 0, "Employee Name: " | &name);
End-For;

✅ This retrieves all rows from the EMPLOYEES rowset and prints each employee’s name.

2. Inserting Data Using PeopleCode SQLExec

Problem: Developers often face issues inserting data dynamically.

Solution: Use SQLExec safely with bind variables.

Local string &emplID = "12345";
Local string &name = "John Doe";

SQLExec("INSERT INTO PS_EMPLOYEES (EMPLID, EMPL_NAME) VALUES (:1, :2)", &emplID, &name);

✅ This ensures safe and dynamic SQL execution while avoiding hardcoded values.

3. How to Debug PeopleCode Efficiently

Problem: Debugging can be difficult without knowing the right tools.

Solution: Use MessageBox, WinMessage, or the PeopleCode Debugger.

MessageBox(0, "Debug Info", 0, 0, "Value of variable: " | &myVariable);

Best Practices:

• Use WinMessage() in Windows clients for immediate alerts.
• Activate PeopleCode Debugger in App Designer for step-by-step execution.

4. Creating a Simple App Engine for Batch Processing

Problem: Developers find it hard to create a simple batch process.

Solution: Create a basic Application Engine (AE).

1. Open App Designer → File → New → Application Engine
2. Create a Section & Step
3. Insert a SQL Action with:

UPDATE PS_EMPLOYEES
SET STATUS = 'ACTIVE'
WHERE STATUS = 'INACTIVE';

4. Save & Register Process in Process Scheduler
5. Run & Monitor in Process Monitor

✅ This automates batch updates efficiently.

5. Fetching Data Using Record Class

Problem: Many struggle with fetching data dynamically.

Solution: Use SelectByKey() for efficient retrieval.

Local Record &rec;

&rec = CreateRecord(Record.EMPLOYEES);
&rec.EMPLID.Value = "12345";
If &rec.SelectByKey() Then
    MessageBox(0, "", 0, 0, "Employee Found: " | &rec.EMPL_NAME.Value);
Else
    MessageBox(0, "", 0, 0, "Employee Not Found");
End-If;

✅ This fetches employee details based on EMPLID.
