Transfer LP type of Scheduling Agreements to APO

Hello All,

My question is about scheduling agreements. In order to plan agreement Scheduling Agreements in APO, the external planning flag in ECC Scheduling Agreement item (additional data) should be set. However, if a schedule line has already been created against SA item, we cannot change this flag. Is there a trick you know to overcome this problem? Actually we found an OSS note for this kind of migration but it is for LPA type of scheduling agreements (658691), here our client use LP type of scheduling agreement. Is there a way to make this migration for LP type of SAs?

Thanks,

Ergü
