Overview

Custom exception class for HTTP error handling in SAP systems, inheriting from CX_STATIC_CHECK. Designed for structured error reporting in HTTP client operations.

  • 4 predefined error types with message placeholders:
  • HTTP client initialization errors
  • Communication failures
  • HTTP processing errors
  • Generic HTTP exceptions
  • Public attributes MV_ATTR1-MV_ATTR4 for dynamic error context

Main method:

CONSTRUCTOR(
  IMPORTING
    !TEXTID        LIKE if_t100_message=>t100key  " Error type selector
    !ATTR1-ATTR4   TYPE STRING                     " Context variables
    !PREVIOUS      LIKE previous                   " Exception chaining

Key implementation notes:

  1. Message variants defined as constants with:
  2. Fixed message ID ZLLM_CLIENT
  3. Unique message numbers (006-009)
  4. Attribute mapping configuration
  5. Constructor enables exception chaining through PREVIOUS parameter
  6. Final class design prevents subclass specialization
  7. Supports up to 4 dynamic context variables for message personalization
  8. Error hierarchy: CX_STATIC_CHECK → ZCX_LLM_HTTP_ERROR
