Ct_data is getting only the changed data

Hello! I have implemented UJ_CUSTOM_LOGIC. The logic seems to work fine when it is run the first time or when the data is cleared and re-run. However when only one or few records are changed and saved in the front end, it isn't working. The reason is CT_DATA is having only the changed records. But I do need all the records in order for the logic/calculations to work.

Do I have to manually read the cube data and compare record by record in the program for the new/changed values or is there another way of doing this?

the script logic has just two parameters QUERY = ON AND WRITE = ON
