## 1. Role

### JBSbatKKDelRun.isSingleCheckKKIFM161_INF1()

This method performs **single-item (field-level) validation** on the "Deletion Target Data (After Eligibility Check)" - a dataset of 22 customer fields that have already passed a higher-level eligibility check and are queued for batch deletion. The business purpose is to ensure data integrity before the system proceeds to actually erase customer records. It validates each field against **byte count constraints** (e.g., 0-2 digits for deletion processing type, 0-256 characters for email) and **character attribute constraints** (e.g., date/time format, email format, phone format) using the shared `JBSbatCheckUtil.invoke()` utility. The method acts as the **final gate** in the eligibility-check phase of the deletion workflow: if any field fails validation, a business error is logged and the method returns `false` to halt the deletion pipeline; if all fields pass, it returns `true` so `execute()` can proceed to persistence-level checks and actual deletion execution. The validation pattern is **sequential short-circuit** - errors are returned on the first field that fails, with no aggregation of multiple validation failures in a single call.

**Control flow summary:** Every field follows the same 3-stage validation pipeline:
1. **Mandatory check** - verifies the field is not null or empty (only `DEL_TRAN_SBT` and `DEL_TRGT_SBT` have this check)
2. **Byte count check** - verifies the field length is within allowed range via `JBSbatCheckUtil.invoke(strValue, new String[]{"ketasuu2", "0", maxBytes})`
3. **Character attribute check** - verifies the content format via `JBSbatCheckUtil.invoke(strValue, new String[]{"attributeName"})`

If any check fails, an error is logged and `false` is returned immediately (short-circuit). Only if all 22 fields pass all their checks does the method return `true`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `rsMap` | `HashMap` | Input data map containing deletion target fields (after eligibility check). Keys are field names like `DEL_TRAN_SBT`, `SVKEI_NO`, `MLAD`, etc. Values are String representations of the field data. Contains data from text files or DB, keyed by the TXT-KKIFM161-INF1 naming convention. |
| 2 | `itemvalueMap` | `HashMap<String, String>` | Error message context map containing display labels for validation error messages. Keys follow the pattern `TXT-KKIFM161-INF1.<FIELD_NAME>` (e.g., `TXT-KKIFM161-INF1.DEL_TRAN_SBT`). Values are human-readable labels displayed to the user when validation errors occur. |

**Instance field accessed:**
| Field | Type | Business Description |
|-------|------|---------------------|
| `commonItem` | `JBSbatCommonItem` | Framework common item object providing access to logging (`getLogPrint()` returns a log printer for business error output). Defined in the parent class `JBSbatBusinessService`. |

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `JKKBatOneTimeLogWriter.printBusinessErrorLog` | - | - | Logs business error messages (EKKB0060TE, EKKB0070TE, EKKB0080TE) to the error log for deletion eligibility check failures |
| - | `JBSbatCheckUtil.invoke` | - | - | Shared field validation utility - validates byte counts and character attributes |

This method performs **no database operations**. It is a pure validation method that reads from the in-memory `rsMap` and writes error logs only. All called services are utility methods (`JBSbatCheckUtil.invoke`) and logging methods (`printBusinessErrorLog`).

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: `JBSbatKKDelRun.execute()` | `execute()` -> `isSingleCheckKKIFM161_INF1(rsMap, itemvalueMap)` | `printBusinessErrorLog` (logging only, no CRUD) |

The method is called directly from `JBSbatKKDelRun.execute()`, which is the main batch processing entry point for the KKIFM161 deletion job. No external screens or CBS call this method directly - it is internal to the batch deletion flow.

## 6. Per-Branch Detail Blocks

**Block 1** — IF (mandatory check) `DEL_TRAN_SBT == null || empty` (L1466)

> Validates the Deletion Processing Type field is not empty. This is the only field (besides DEL_TRGT_SBT) with a mandatory (null/empty) check.

| # | Type | Code |
|---|------|------|
| 1 | SET | `strValue = (String)rsMap.get("DEL_TRAN_SBT")` // Retrieve deletion processing type |
| 2 | IF | `strValue == null || "".equals(strValue)` [EKKB0060TE - mandatory field error] |
| 3 | EXEC | `commonItem.getLogPrint().printBusinessErrorLog("EKKB0060TE", new String[]{itemvalueMap.get("TXT-KKIFM161-INF1.DEL_TRAN_SBT")})` // Log mandatory field missing |
| 4 | RETURN | `return false` // Field is mandatory and empty |

**Block 2** — IF (byte count check) `DEL_TRAN_SBT` max 1 digit (L1473)

| # | Type | Code |
|---|------|------|
| 1 | IF | `!JBSbatCheckUtil.invoke(strValue, new String[]{"ketasuu2", "0", "1"})` // Max 1 byte |
| 2 | EXEC | `commonItem.getLogPrint().printBusinessErrorLog("EKKB0070TE", ...)` // Log byte count error |
| 3 | RETURN | `return false` |

**Block 3** — IF (attribute check) `DEL_TRAN_SBT` hannkakuesuuji1 (L1481)

| # | Type | Code |
