Tcode VT02N --> ShipmentNo--> Output-->Screen, O/P Type Y141, Y011

System has been upgraded from 4.7 to 6.0

It prints the lines in DE and NL but not in EN. After analyzing it was found that the FMs HAZMATEDI_READ_DG_DATA_ have been upgraded and it's behaving differently. There is an FM READText_ which reads the Texts based on HEADER_TEXT-LANGU. This HEADER_TEXT-LANGU is being populated somehow through the FM HAZMATEDI_READ_DG_DATA_.

Please help with the possible causes and remedies.

Thanks
