Object name is not allowed to be empty

Hello,

I am getting error while loading data in 0MATERIAL hierarchy.

The error message is "Object name is not allowed to be empty".I could saa lots of post related to this error,but nothing helped.

The scenario si :

We are extracting data in a flat file from one of the DSO in BW and loading flat file data to 0MATERIAL hieararchy.

Now I can understand where the issue is.For one of the Node ID,the infoofbject field has no value assigned to it.

Now I don't understand how to handle the error.The job is failing regularly due to this.Please help

Regards,

Neetu
