SIW091 - Structure &2: Field description &1 is invalid (see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: SIW - Service Implementation Workbench

• Message number: 091

• Message text: Structure &2: Field description &1 is invalid (see long text)

What causes this issue?

The configuration of the structure object &v2& is inconsistent. Specify
either a predefined type via the fields DATATYPE [LENG, DECIMALS,
DDTEXT] or specify a component type via ROLLNAME.

System Response

The system cannot fill the fields automatically and therefore not
generate the structure object &v2&.

How to fix this error?

To enable the system to fill the fields, correct the configuration of
the structure field description &v2&. To do so, you can either specify
the DATATYPE or the ROLLNAME field as follows:
To specify the DATATYPE field, enter Initial as value for the ROLLNAME
field first. Then specify a predefined type for the DATATYPE field.
Optionally you can enter values for the LENG, DECIMALS, and DDTEXT
fields.
To specify the ROLLNAME, enter Initial as value for the fields DATATYPE,
LENG, DECIMALS and DDTEXT first. Additionally you have the following
possibilities:
- Specify a data dictionary type for the ROLLNAME field. In case you
want to embed a structure you can set FIELDNAME = .INCLUDE.
- Specify a reference type for the ROLLNAME field and specify the
mandatory REFTYPE field.
