You are doing Service order relevant postings. The account used in the posting is a Primary Cost Element, instead of Secondary Cost Element.
SAP S/4HANA Cloud
Account determination customizing:
SSCUI 102921, 102920.
There are two ways for account determination in service order postings according to current design:
1. The Primary Cost Element, which is configured in the mentioned SSCUI, is used for expense posting (cost element category = 01)
2. The Secondary Cost Element, which is derived from activity type master data, is used for service posting (via CATS)
Travel costs are kind of expense costs. It cannot be mapped to any activity type, so the Primary Cost Element is used.
