BBP_RFC_READ_TABLE¶

SRM/EBP variant of RFC_READ_TABLE with extended row support.

Purpose¶

BBP_RFC_READ_TABLE is a drop-in replacement for RFC_READ_TABLE that lifts the 512-byte row width restriction. It originated in the SAP SRM (Supplier Relationship Management) / EBP component, but it is frequently present on ECC and S/4HANA systems as a side-effect of SRM transport imports — making it more widely available than /BODS/RFC_READ_TABLE.

Not part of the standard kernel

BBP_RFC_READ_TABLE is delivered via the SRM/EBP software component. Its presence depends on which components have been imported into the target system. Always check SE37 before relying on it.

Signature¶

Identical to RFC_READ_TABLE — swap the function module name and the rest of the code is unchanged.

Parameter	Direction	Type	Notes
`QUERY_TABLE`	IMPORTING	`DD02L-TABNAME`	Table to read. Required.
`DELIMITER`	IMPORTING	`CHAR1`	Column separator in the output. Use `\\|` to avoid collisions.
`NO_DATA`	IMPORTING	`CHAR1`	Pass `'X'` to return field metadata only.
`ROWSKIPS`	IMPORTING	`INT4`	Skip first N rows (pagination).
`ROWCOUNT`	IMPORTING	`INT4`	Max rows to return (0 = all).
`FIELDS`	TABLES	`RFC_DB_FLD`	Fields to return. Empty = all fields.
`OPTIONS`	TABLES	`RFC_DB_OPT`	WHERE clause fragments, max 72 chars each.
`DATA`	TABLES	`TAB512`	Output rows as flat strings split by `DELIMITER`.

Example — using BBP_RFC_READ_TABLE as a fallback¶

DATA: lt_fields  TYPE STANDARD TABLE OF rfc_db_fld,
      lt_options TYPE STANDARD TABLE OF rfc_db_opt,
      lt_data    TYPE STANDARD TABLE OF tab512.
DATA: lv_fm_name TYPE rs38l-name.

APPEND VALUE rfc_db_fld( fieldname = 'LIFNR' ) TO lt_fields.
APPEND VALUE rfc_db_fld( fieldname = 'NAME1' ) TO lt_fields.
APPEND VALUE rfc_db_opt( text = 'MANDT = SY-MANDT' ) TO lt_options.

Availability in practice

In many ECC and S/4HANA landscapes that have or had SRM installed, BBP_RFC_READ_TABLE is present even if the SRM system itself was decommissioned. It's a reasonable first fallback before resorting to a custom FM.

Common pitfalls¶

Component dependency: the FM belongs to the SRM/EBP delivery — it is not guaranteed on a vanilla ECC or S/4HANA system without SRM transports.
Same WHERE clause rules: each OPTIONS row is still limited to 72 characters. Concatenate longer conditions across multiple rows.
Client filtering: does not automatically filter by client. Add MANDT = SY-MANDT to OPTIONS for client-dependent tables.
Authorization: S_TABU_DIS activity 03 is still required for the target table's authorization group.
Ultimate fallback: if both BBP_RFC_READ_TABLE and /BODS/RFC_READ_TABLE are missing, write a custom RFC-enabled FM with a proper typed SELECT — it will be more performant anyway.
