SQL Query (using MS SQL) to give you all executions.
You could select Top 1 or add a MAX() function to get the most recent executions. Maybe consider having the ReturnCode there also.
SELECT OH.OH_Name, OH_Client, AH_Timestamp1 as ActivationTime, AH_Timestamp2 as StartTime, AH_Timestamp3 as EndTime, AH_Timestamp4 as PoCoEndTime
from OH (NOLOCK)
JOIN AH (NOLOCK) on AH.AH_OH_Idnr = OH.OH_Idnr
where OH.OH_Client = 100 --Client
AND OH_Name = 'YOUR.OBJECT' --Name of the object
ORDER BY AH.AH_TimeStamp1 -- orders by activation time
