SAP Error Message - Details

• Message type: E = Error

• Message class: CRD_REQBUILD - Credentialing: Generate Requirements

• Message number: 103

• Message text: Nesting depth of requirements too large; maximum depth &1, requirement &2

What causes this issue?

While generating <DS:GLOS.44A21B945F2E4D36E10000000A114B08>requirements
</> , the <ZH>maximum</> hierarchy depth of the generated tree was
reached. Therefore the requirement <ZH>cannot</> be generated correctly
in the system.

System Response

The activity is canceled.

How to fix this error?

Check the Customiziong for requirements. The maximum depth allowed for
the tree of a requirement is &V1&; the requirement in which the problem
occurs is requirement &V2&.

• What is the cause and solution for SAP error message CRD_REQBUILD103 - Nesting depth of requirements too large; maximum depth &1, requirement &2 ?

  The SAP error message CRD_REQBUILD103 indicates that the nesting depth of requirements in a certain configuration or planning scenario has exceeded the maximum allowed limit. This typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where complex product structures or planning scenarios are involved.
  Cause:
  
  Complex Product Structures: The error often arises when there are too many levels of dependent requirements in a product structure, such as when a finished product has multiple components, each of which may have its own sub-components.
  Configuration Issues: If the configuration of the product is overly complex, it can lead to deep nesting of requirements.
  Data Integrity Issues: Incorrect or incomplete data in the master data (like BOMs, routings, or configuration profiles) can also lead to excessive nesting.
  
  Solution:
  
  Simplify Product Structures: Review and simplify the product structure if possible. Reducing the number of levels in the Bill of Materials (BOM) can help mitigate the issue.
  Check Configuration Profiles: Ensure that the configuration profiles are set up correctly and do not lead to unnecessary complexity.
  Review Requirements: Analyze the requirements being generated and see if there are any unnecessary dependencies that can be removed or simplified.
  Adjust System Parameters: If feasible, consult with your SAP Basis or technical team to see if there are system parameters that can be adjusted to allow for a greater nesting depth, though this is generally not recommended as a first step.
  Data Cleanup: Ensure that all master data is accurate and complete. This includes checking BOMs, routings, and any other relevant data that could contribute to the nesting depth.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on best practices for managing product structures and requirements.
  Documentation: Review SAP documentation related to product configuration, BOM management, and requirement planning to understand the limitations and best practices.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  If the problem persists after trying the above solutions, it may be beneficial to engage with SAP support for further assistance.
