HANA DU Import and Schema Mapping Error

Hi,

I have strange issue when importing Delivery Unit from Quality System(ECQ) to Prd HANA(ECP) System.

The schema mapping is as follows

1. DEV

2. Quality and Live

When The DU is imported from ECD into ECQ , the model gets activated and they refer to the correct schema ie SAPECP.

But when the DU is imported from ECQ into ECP, the models refer to SAPECD schema only, there by getting error on execution.

Please advise as what can be the cause of this issue. HANA Version is : 1.00.097.xx

TIA,

Vijay
