How To Fix GS090 - Sólo los sets basicos pueden comenzar por '0W'.

SAP Error Message - Details

• Message type: E = Error

• Message class: GS - Sets

• Message number: 090

• Message text: Sólo los sets basicos pueden comenzar por '0W'.

¿Qué causa este problema?

'0W' as the beginning of a set name is reserved exclusively for basic
sets belonging to WBS elements.
These sets are designed especially to show the intervals in the WBS
elements. When the sets are imported from the WBS element's master
data, they are then broken down by the set manager into their individual
values. They can only be created as basic sets belonging to table
fields with the domain PS_POSNR, that is, for example, PRPS-PSPNR.

Respuesta del sistema

The set cannot be created.

¿Cómo arreglar este error?

If you want to create a '0W' set, it must be a basic set.
If you want to create a different type of set, the set name cannot begin
with '0W'.
