Error analysis

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_TOO_MANY_FILES', was not

caught and

therefore caused a runtime error.

The reason for the exception is:

The maximum number of open files (100) has been exceeded.

Standard programming problem, should be rather trivial to find with a quick search. Basically there's always a limit of how many open file handles you can have at a time.

Please try to consult the ABAP help next time before posting (or search on SCN). A quick check for [open dataset|http://help.sap.com/abapdocu_70/en/ABAPOPEN_DATASET.htm] would've told you the following:

You can open up to 100 files per internal session. The actual maximum number of simultaneously open files may be less, depending on the platform.

Most likely you actually don't want to have all those files open at the same time and you simply forgot to use a [close dataset|http://help.sap.com/abapdocu_70/en/ABAPCLOSE_DATASET.htm] after reading each file.
