Error message V4016 when creating a new FD schedule

Hello All,

While processing an incoming IDOC for FD schedule , I am coming across an error message which says "Save your changes first", although the FD schedule has not been changed before.

A little googling has let me come across a SAP note 659012, but this is valid till Release 4.7. My client is in ECC 6.0 and I am not able to find any similar notes for ECC 6.0.

Can anybody help me with this issue buy suggesting a suitable SAP note or in that case with some advise in rectifying the problem.

BR,
