## 1. Role

### JKKMltiseInfoAddCfmCC.editEKK0011D020ErrorInfo()

This method serves as the error-mapping bridge between the CBS (Common Business System) response layer and the screen presentation layer for the Service Contract Line Details List Inquiry S-IF (screen EKK0011D020). After the CBS execution layer runs the inquiry processing and populates a CAANMsg[] template array with result codes and error messages, this method extracts all error information from the template(s) and writes them into a HashMap stored within the IRequestParameterReadWrite parameter object, making the errors available for display on the inquiry result screen.

The method follows a transformation/delegation pattern: it receives pre-populated message templates from the CBS layer and transforms their structured error fields into a flat key-value structure the UI layer can consume. It handles two tiers of error data: (1) header-level errors (top-level template fields for the entire inquiry result), and (2) detail-level errors (per-line-item errors for each row in the returned list, stored under the key "EKK0011D020CBSMsg1List" as an ArrayList<HashMap>).

Its role in the larger system is that of a shared error-mapping utility called by the result-presentation method editEKK0011D020ResultRP() after the CBS call completes. The method is idempotent with respect to individual fields (it checks containsKey to avoid overwriting existing values) but operates on the full request parameter object, modifying it in place. No database or SC (Service Component) calls are made by this method - it is a pure data transformation method that bridges CBS responses to screen display data.

### Processing Steps Summary

1. **Extract template** - Retrieve the first element from the CAANMsg[] templates array.
2. **Set control map** - Call setControlMap() to configure error display controls (status codes, field-level error flags) on the screen form.
3. **Retrieve/Initialize inHash** - Get the HashMap from param using the fixedText key. If null, create a new HashMap and store it back in param.
4. **Header-level error mapping** - Iterate through 22 header-level error fields. For each field, if the template contains a non-null error value, store it in the HashMap under a flat key (e.g., sysid_err). The containsKey check prevents overwriting.
5. **Detail-level list initialization** - Retrieve the ArrayList for child items from inHash. If null, create a new ArrayList and store it.
6. **Extract detail template array** - Get the CAANMsg[] array from the template for child-level messages via getCAANMsgList(EKK0011D020CBSMSG1LIST).
7. **Detail-level error mapping loop** - For each child template in the array, ensure a HashMap exists at index i in inList, then map 27 per-line error fields to the child HashMap.
8. **List-level error mapping** - Check if the template has a list-level error (EKK0011D020CBSMSG1LIST_ERR) and store it in inHash.
9. **Return** - Return the modified param object with all error data mapped.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | IRequestParameterReadWrite | The business data request/response parameter object. Carries the work context through the processing chain. Contains the result data stored under the key specified by `fixedText`. Modified in place to include error-mapped HashMaps. |
| 2 | `templates` | CAANMsg[] | Array of CAANMsg message objects containing CBS response data. The first element (templates[0]) is the primary response template containing header-level error fields. It also contains a nested CAANMsg[] list under the key EKK0011D020CBSMSG1LIST for per-line-item detail errors. |
| 3 | `returnCode` | int | Return code from the CBS call. Passed through to setControlMap() to configure the screen status/error display based on the CBS result. |
| 4 | `fixedText` | String | The key used to store/retrieve the error HashMap within param. Acts as the namespace for error data within the parameter object. |

### Instance Fields / External State

| Name | Type | Description |
|------|------|-------------|
| `setControlMap` (called method) | Method on this class | Sets error control configuration (status codes, field error flags) on the screen form. Uses the STATUS constant to identify the error group. |

## 4. CRUD Operations / Called Services

This method performs no direct CRUD operations on databases or service components. It is a pure data transformation layer that:
- **Reads** error fields from the CAANMsg templates (via template.isNull() and template.getString())
- **Writes** error data into the HashMap within the param object (via inHash.put() and inList.add())
- **Calls** setControlMap() to configure screen-level error display controls

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `setControlMap` | JKKMltiseInfoAddCfmCC | - | Sets error control configuration (status codes, field error flags) on the screen form for the EKK0011D020 error group. No DB access - purely UI presentation setup. |
| R | `template.isNull` | N/A (CAANMsg method) | N/A | Checks whether a CBS error field is null/empty. Non-null means an error exists for that field. |
| R | `template.getString` | N/A (CAANMsg method) | N/A | Reads the error message string from a CBS template field. |
| R | `param.getData` | N/A | N/A | Reads the existing HashMap from the param object using the fixedText key. |
| W | `param.setData` | N/A | N/A | Writes the HashMap (initialized or modified) back into the param object. |
| W | `inHash.put` | N/A | N/A | Stores error key-value pairs into the header-level error HashMap. |
| C | `inList.add` | N/A | N/A | Adds new HashMap entries for child-level error rows. |

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | JKKMltiseInfoAddCfmCC | editEKK0011D020ResultRP() -> editEKK0011D020ErrorInfo() | terminal: template.isNull [-], template.getString [R], param.getData [R], param.setData [W], inHash.put [W], inList.add [C] |

### Call Direction Summary

```
editEKK0011D020ResultRP()
  -> editEKK0011D020ErrorInfo(param, templates, returnCode, fixedText)
        -> setControlMap(param, templates, returnCode, EKK0011D020CBSMsg.STATUS)
        -> (reads from templates, writes to param inHash/inList)
```

This method is called by editEKK0011D020ResultRP() within the same class. It is a helper/utility method that processes CBS response data into a format suitable for screen presentation. No further terminal operations (DB, SC, CBS) are reached from this method.

### Block 25.1 - [FOR] Detail-level error mapping loop (L2975)

Iterates over each child template and maps its error fields.

| # | Type | Code |
|---|------|------|
| 1 | SET | `int i = 0` (loop counter) |
| 2 | SET | `i < templateArray.length` (loop condition) |
| 3 | INC | `i++` |

#### Block 25.1.3 - [IF] Child-level error mappings (L2983-L3170)

Maps 27 per-line-item error fields from each child template. Each follows the same pattern: null check -> containsKey guard -> put.
