• What is the cause and solution for SAP error message RTCMMD135 - First adjust the validity period of the direct lower-lever assignments ?

  The SAP error message RTCMMD135, which states "First adjust the validity period of the direct lower-level assignments," typically occurs in the context of managing master data, particularly in the areas of material management or production planning. This error indicates that there is a conflict with the validity periods of the assignments in a hierarchy or structure, such as a bill of materials (BOM) or a routing.
  Cause:
  The error arises when you attempt to change or delete a higher-level assignment (like a parent item) that has lower-level assignments (like child items) with overlapping validity periods. The system requires that all lower-level assignments must have their validity periods adjusted or removed before you can make changes to the higher-level assignment.
  Solution:
  To resolve this error, follow these steps:
  
  
  Identify the Lower-Level Assignments: Determine which lower-level assignments are linked to the higher-level assignment that you are trying to modify. You can usually find this information in the relevant transaction or by using reports that show the hierarchy.
  
  
  Check Validity Periods: Review the validity periods of the lower-level assignments. You need to ensure that there are no overlaps with the higher-level assignment's validity period.
  
  
  Adjust Validity Periods: 
  
  If the lower-level assignments have validity periods that overlap with the higher-level assignment, you will need to adjust these periods. This can involve extending, shortening, or removing the validity periods of the lower-level assignments.
  You can do this in the relevant transaction (e.g., for BOMs, use transaction CS02; for routings, use transaction CA02).
  
  
  
  Re-attempt the Change: Once the validity periods of the lower-level assignments have been adjusted, you can re-attempt the change to the higher-level assignment.
  
  
  Check for Dependencies: Ensure that there are no other dependencies or constraints that might affect the validity periods of the assignments.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CA01 (Create Routing), and CA02 (Change Routing).
  Master Data Management: Understanding how master data is structured in SAP can help prevent such errors in the future. This includes knowing how validity periods work and how they relate to different levels of data.
  SAP Notes and Documentation: Check SAP Notes for any specific patches or updates related to this error message. SAP's help documentation can also provide insights into managing validity periods effectively.
