etc..

This is a somewhat big file that is being loaded.

What is row F10-1 etc..?

The LOAD utility partitions the input file to enable parallel processing. F10-1 means row 1 in partition 11. If you are not in a DPF environment, specify CPU_PARALLELISM 1 to disable partitioning, then F0-1 will refer to the first row in the input file. In a DPF environment you would need to use MODE PARTITION_ONLY to save the partitioned input files, then use LOAD_ONLY; the errors will reference the input file on each partition.
