Avoid Obsolete ABAP Memory and Context Statements

WarningAnti-Patterns & Bad Practices#EC NO_OBS_MEMORYRemote Enabled

Overview

Obsolete Memory and Context Statements.

ATC Finding Message: Avoid obsolete memory, context, and legacy data-sharing constructs

Rationale

ABAP memory and database cluster statements (EXPORT ... TO MEMORY / DATABASE, FREE MEMORY) and Context commands (CONTEXTS, DEMAND, SUPPLY, PROVIDE) rely on hidden shared memory regions that break statelessness, multi-tenancy, and testability. In cloud systems, communicate explicitly via method parameters, database repositories, or session services.

Non-Compliant

EXPORT user_id = lv_user TO MEMORY ID 'USR_CTX'.
FREE MEMORY ID 'USR_CTX'.

Compliant

" Pass user context explicitly via method arguments or a dedicated context provider service.

Configuration & Thresholds

This check can be fine-tuned directly in the ATC Check Variant Editor (CHKV) in Eclipse ADT:

Parameter Name	Data Type	Default Value	Description & Guidance
CHECK_EXPORT_MEMORY	Boolean	true	Detect obsolete EXPORT TO MEMORY statements
CHECK_FREE_MEMORY	Boolean	true	Detect obsolete FREE MEMORY statements
CHECK_PROVIDE	Boolean	true	Detect obsolete PROVIDE statements
CHECK_CONTEXTS	Boolean	true	Detect obsolete CONTEXTS statements
CHECK_INFOTYPES	Boolean	true	Detect obsolete INFOTYPES statements
CHECK_COMMUNICATION	Boolean	true	Detect obsolete COMMUNICATION statements
CHECK_CALL_TRANSF	Boolean	true	Detect obsolete CALL TRANSFORMATION XML statements

Suppression

To suppress findings for this rule, append the pseudo-comment to the statement:

" Standard pseudo-comment:
... "#EC NO_OBS_MEMORY

" SAP CI_ prefix format:
... "#EC CI_NO_OBS_MEMORY
