BW Infosource exraction error

Hi ,

Our project recently got upgraded from DS3.1 to 4.0 .  After moving to 4.0 , we

are trying to import a BW master structure but unable to import , PFA error for

your reference .

This is affecting our data load . What we noticed is that only master  transfer

structures whcih does not have any ATTRIBUTE associated is giving us the problem.

Any input on this is highly appreciated ! Awaiting your early response .

thnx,
Rani
