Hi,
we are experiencing an issue with multilevel cost calculation for purchased parts containing manufactured parts on lower levels, which appears to have started after upgrading to IFS Cloud 26R1.
The structure is approximately:
Purchased Part → Manufactured Part → Manufactured Part → Purchased Part
The Purchase Cost Template has both Use Manufacturing Costs and Use External Acquired Costs enabled.
Before the 26R1 upgrade, the multilevel cost calculation worked correctly with this configuration. However, after the upgrade, running All Levels Part Cost Calculation into Cost Set 2 does not roll up the lower-level manufactured structure and its costs.
We were able to reproduce the behavior on multiple parts.
As a test, we disabled Use Manufacturing Costs while keeping Use External Acquired Costs enabled and recalculated the same part. Without any changes to the product structure or routing, the complete multilevel structure and costs were rolled up correctly.
Example:
- Previous Cost Set 1 (calculated before 26R1): 96.14827 CNY
- New Cost Set 2 with Use Manufacturing Costs = Yes: 19.777 CNY – lower levels missing
- New Cost Set 2 with Use Manufacturing Costs = No: 96.14827 CNY – complete multilevel structure
The recalculated result with Use Manufacturing Costs disabled therefore exactly matches the previous Cost Set 1 result.
Has there been any change in the Cost Rollup Control logic in 26R1, specifically regarding Use Manufacturing Costs for Purchase Cost Templates?
Is this expected behavior in 26R1, or could this be a regression in the multilevel cost calculation?
