Errormessage DATA_OFFSET_LENGTH_TOO_LARGE with GUI_UPLOAD

Hello experts,

I get a runtime error with the errormessage DATA_OFFSET_LENGTH_TOO_LARGE when using GUI_UPLOAD to upload a dataset.

I use a txt-dataset (separator '#').

It seems to me that R/3 cannot detect a lineend.

Is there a special lineend-seperator?

Or does anybody have a different solution?

Kind regards

Udo
