• Message number: 331

• Message text: Component type &1 may not contain further component types

What causes this issue?

Simple component types (such as calculation, input, output, and
pushbutton) that you define in XSL style sheets for cockpits or PI
sheets may not contain further components. Grouping component types, on
the other hand, may contain further components.Tables, for example, may
contain pushbuttons or input fields.
In the XSL style sheet you used, however, further component types have
been assigned to component type &V1&. This is not permitted.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Correct the definition of component type &V1& in the XSL style sheet
you used.

• What is the cause and solution for SAP error message CPOC331 - Component type &1 may not contain further component types ?

  The SAP error message CPOC331 indicates that a component type in a certain context (usually related to Product Structure or Bill of Materials) is not allowed to contain further component types. This typically occurs in scenarios where a component type is defined as a "leaf" node in a hierarchy, meaning it cannot have sub-components.
  Cause:
  
  Incorrect Configuration: The component type you are trying to add as a sub-component is configured in such a way that it is not allowed to have further components. This could be due to the settings in the material master or the configuration of the product structure.
  Hierarchy Restrictions: The system may have restrictions on certain component types that prevent them from being used as parent components in a hierarchy.
  Data Entry Error: There might be a mistake in the way the components are being entered or structured in the system.
  
  Solution:
  
  Check Component Type Configuration: Review the configuration of the component type in question. Ensure that it is set up to allow sub-components if that is the intended design.
  Use Correct Component Type: If the component type is not meant to have sub-components, you should use a different component type that is allowed to contain further components.
  Review Product Structure: Look at the overall product structure to ensure that the hierarchy is set up correctly and that you are not trying to add a component type inappropriately.
  Consult Documentation: Refer to SAP documentation or configuration guides for the specific module you are working with to understand the rules governing component types.
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Transaction Codes: Familiarize yourself with transaction codes related to product structure management, such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM).
  Material Master: Review the material master data for the component types involved to ensure they are set up correctly.
  Training and Documentation: Consider training sessions or documentation on product structure management in SAP to better understand how to configure and manage component types.
  
  By following these steps, you should be able to identify the cause of the CPOC331 error and implement a suitable solution.
