Introduction
After working with SAP for more than 15 years and travelling across the Globe for SAP Projects one issue I always use to have how can I keep track of all the SAP Tables associated with different Modules. If you are working as a SAP ABAP Consultant in every Project you go you have to deal with ChangeDocument Object for a Particular Transaction. I found a very easy way to determine the Change Document Object of Tables without going to the Specific Transaction Code by just knowing the Actual Table Name. If you are working in SAP you always need to understand everything is a Table Entry
🙂
Solution
Go to Transaction Code SE16->Enter Table TCDOB and Press Enter

Now Enter the Table for which you want to Find the Change Document Object.
Here in our example it would be EKKO(Purchase Order Header Table) Now we execute

Wala we go our result EINKBELEG

Conclusion
You can use the same process to find any Changedocument Object both in SAP ECC and SAP S/4 HANA
