Hello @aish_TF ,

I assume you have performed a SRG (Save-Reload-Generate) after adding the new complex delta load operations. To ensure they are added to the configuration, you could check the nme-batch.gen.xml file located under Files-->etc folder, in your workspace/project directory:
 

If everything went well, you should see an entry similar to this in this file, one for each complex delta load you configured:

 

Try a server restart after this, and you should see the load operations in Admin Center. 

Hi @ivysakh 

Thank you for the response. I did Generate but not at the project level but at the connected system level to generate the load component files.
Will keep in mind regarding the nme.batch.gen.xml file for future. 

Thanks a lot :)
