I am facing problem while importing products. I have more than 200 categories and every category have more than 200 products. All the time products were imported successfully. But suddenly it stuck with one category I imported earlier and it was imported succcessfully. But next time when I try to import the csv file then the dataflow loads old one. For example. previously I have imported 463 records. After that I am trying to import next records. But it again loads 463 rows. I tried many times. For this I created another profile, truncate the table dataflow_batch_export and dataflow_batch_import, clear the cache, reindex the file. But I did not get any success.
Please guide me. I am stuck and I have to upload lots products.
