SAP Message >U155 - File version could not be determined

Diagnosis
From Release 4.61 you can include version information in the folderrecord when you transfer data. This informs the transfer program whichdata structure was used as the basis for creating the file (Release461, 451 or 400). This information is not available for the file inquestion. The program thus tried to determine the correct version onthe basis of the length information in the data dictionary and on thelength of the file line. Because customer includes are linked to thecorresponding tables in your system, this attempt was unsuccessful.

System Response
The file cannot be processed.

Procedure
You must change the program for creating the transfer file so that italso contains version information in the folder record.
