issue with BP integration after ALE transfert using HRMD_A

Hi

i use ECC 6 ehp7. In dev, i use P records created from PA30 with BP integration. It's working fine.

Then, i transfered P records from dev to QUAL using ALE (HRMD_A idoc + pfal).

In Qual, i get my P records in PA30 -> good.

Yet, in qual, BP records are not created despite the active P-BP integration :-( ...

i tried to use report HRALXSYNC for fixing the issue : nothing get selected ... ->no fix ..

any idea of the reason of this ? any guide/cookbook to follow in order to transfer PA records with active BP integration ?

Thanks

Regards
