proces chain failure

dear gurus,

i'm loading the data from datasource to infoobjects, there are 2 different chains for attr, text(deltas).

the delta load to text is successful but to attr has failed.

so i've changed the request of attr to red so that i could delete the bad request and run the infopackage to get the deltas again.

now its showing a warning saying that if i run the infopackage there will be duplicate records for text.

please suggest me some solution for this.

thanks in advance.
