Hi All,
In case you are facing unusual issue as below during check-in of TU and your TU status is not changed from planned to active:
Category ABAP Programming Error
Runtime Errors ASSERTION_FAILED
ABAP Program /SCWM/SAPLHU_TO_UPD
Application Component SCM-EWM-WOP
Plz use the below solution from note - Note # 2103623 - Capacity data in yard, released recently by SAP. It is caused due to Capacity check issues in S&R in SAP EWM.
Plz run report - /SCWM/RWEIGHT_VOLUME_UPDATE, this will update your storage types and will help you check-in TU successfully and also change the status from Planned to Active.
Or better, before starting S&R in EWM, plz run this report so you don't face this issue at-all. This happened to me in SAP EWM 9.3 system, hence can be an issue to you too.
