One BP is mapped to a Plant & a Supplier

Hello Experts,

We have a situation in our production system, A plant's description was kept on changing frequently to an unwanted description.

To repair this we used to run Plant replication program. But it was again getting changed to unwanted description. On more investigation we found that, The same BP which is mapped to Plant is also mapped to a Supplier from same back-end ERP system. Hence because of vendor sync Job, it was replicating the vendor description to the BP.

Now we need to repair this scenario. Kindly suggest us, as it in production system from more than 6 month.

Thanks lot.

Regards,

Nitin
