BW 3.5 to BI 7.0 Upgrade - ABAP OO migration
We have written all our ABAP routines, update rules, etc in regular ABAP in BW 3.5.
Do we need to migrate all the regular ABAP to ABAP Object Oriented in BI 7.0 ?
Or will the regular ABAP still work in BI 7.0.
Does the new BI 7.0 functionality require ABAP OO ?
