bw_create_infoobject

Create an inactive InfoObject (characteristic or key figure) in SAP BW/4HANA. Specify object type, name, info area, and additional attributes like data type and length.

Instructions

Create a new InfoObject — Characteristic (CHA) or Key Figure (KYF) — inactive. Sequence: lock → POST create → unlock. After creation call bw_activate with object_type "iobj" to activate.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
infoobject_typeNoInfoObject type: CHA (Characteristic) or KYF (Key Figure). Default "CHA".
nameYesInfoObject name, max 9 characters (e.g. "IOBJ_NAME").
info_areaYesInfoArea to assign the InfoObject to (e.g. "NEXTJUICE").
descriptionYesShort and long description text.
data_typeNoCHA only. ABAP data type. Default "CHAR".
lengthNoCHA only. Field length. Default 10.
conversion_routineNoCHA only. Conversion routine (e.g. "ALPHA"). Default "ALPHA" for CHAR/NUMC, "" for others.
with_master_dataNoCHA only. Generate master data tables. Default false.
with_textsNoCHA only. Generate text tables. Default false.
referenced_infoobjectNoCHA only. Reference to an existing InfoObject (e.g. "IOBJ_NAME"). Omit withMasterData/withTexts — they are inherited. Default "".
compound_infoobjectsNoTechnical names of the compound parent InfoObjects, in order. CHA only. Example: ["COMPND_IOBJ_NAME"].
object_specific_data_typeNoKYF only. Data type. Default "DEC". keyfigureType and semantics are derived automatically.
aggregation_typeNoKYF only. Aggregation type. Default "SUM".
fixed_unitNoFixed unit of measure for QUAN key figures (e.g. "KWH", "M3"). Required when object_specific_data_type is QUAN.
fixed_currencyNoFixed currency for CURR key figures (e.g. "EUR"). Required when object_specific_data_type is CURR.
packageNoDevelopment package. Default "$TMP".
transportNoTransport request number (e.g. DEVK900123). Only required if the BW system requires transport assignment.
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Discloses that the InfoObject is created inactive and that a lock/unlock sequence is used. Since no annotations are provided, the description carries the burden and adds useful behavioral context beyond the schema, such as requiring activation post-creation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with purpose, then sequence and activation step. No fluff, every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 17 parameters, no output schema, and no annotations, the description explains the core purpose and activation step but lacks details on return values, error handling, or when to use this over other creation tools (e.g., bw_create_adso). Adequate but leaves some gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description does not add any parameter-level details beyond what the schema already provides; it focuses on the overall workflow.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'Create a new InfoObject — Characteristic (CHA) or Key Figure (KYF) — inactive', specifying verb, resource, and types. It distinguishes from sibling tools like bw_activate and bw_update_infoobject.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit instructions: 'After creation call bw_activate with object_type "iobj" to activate.' and describes the sequence 'lock → POST create → unlock'. Does not explicitly mention alternatives but context with siblings makes creation purpose clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
