Error when importing BW 7.x transaction transfer structure in BODS 4.2

Hello Experts,

We are on BODS 4.2 and BW 7.4.

Prior to BW 7.4, the BW transaction transfer structures were in 3.x and everything worked well in BODS 4.0.

When we migrated to BW 7.4 and BODS 4.2, then we also migrated the BW transaction transfer structures from 3.x to 7.x. When I trired to re-import this structure under the BW datastore in data services designer, I get the below error message.

Any help will be appreciated.

Thanks

Ann
