issue when number of records in a DSO exceeds DTP package size

Hi all,

I'm having a strange problem with the package size of my DTPs.

I move data from a DSO to another one while performing some transformations in an Export routine. The DTP has a package size of 6 million records.

When the number of records in the first DSO exceeds the package size, some of the records seem not to be processed properly by the transformation and this forces me to choose a very large number for the package size so that the ABAP code in the transformation is processed for all the records of the source DSO.

I can't understand why this is happening because package size is only supposed to determine the number of records to be processed in a single step and nothing else.

Am I right?

Thanks
