In this step you can display the structure of the IDoc ACLREC01, which is used to update data from an external billing system to Profitability Analysis.
This also contains the CO-PA-specific segments that you need to use if you want to update the data in CO-PA.
To make the data transfer possible, the segments and segment fields of the external data need to be assigned automatically to the fields in Profitability Analysis.
Enter the object name "ACLREC01" and choose "Tree display". You will find the CO-PA-specific segments under the segment E1ACA1. There you can also find documentation on the IDoc structure.
