Smart SAP Assistant

• What is the cause and solution for SAP error message DMC_DTL264 - Change not allowed: Access Plan is part of coll. access plan or precalc. ?

  The SAP error message DMC_DTL264 indicates that a change is not allowed because the access plan you are trying to modify is part of a collective access plan or a pre-calculated access plan. This typically occurs in the context of SAP Data Management, particularly when dealing with data models, data flows, or data transformations in SAP Data Intelligence or SAP BW.
  Cause:
  
  
  Collective Access Plan: The access plan you are trying to change is part of a collective access plan, which means it is grouped with other access plans for optimization purposes. Changes to individual access plans in this context are restricted to maintain the integrity of the collective plan.
  
  
  Pre-calculated Access Plan: If the access plan is pre-calculated, it means that the results have already been computed and stored. Modifying the access plan could invalidate the pre-calculated results, hence the restriction.
  
  
  Solution:
  
  
  Review Access Plan: Check if the access plan is indeed part of a collective or pre-calculated access plan. You may need to identify the parent plan or the context in which it is being used.
  
  
  Modify Parent Plan: If you need to make changes, consider modifying the collective access plan or the pre-calculated access plan instead of the individual access plan.
  
  
  Create a New Access Plan: If the changes are necessary and cannot be made to the existing access plan, consider creating a new access plan that meets your requirements without affecting the existing ones.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing access plans in your version of SAP. This can provide insights into best practices and limitations.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance. They can provide guidance based on your specific system configuration and requirements.
