Transferring goods between Bitrix infoblocks?

Question

1C-Bitrix

Guys, tell me this question.
It is necessary to transfer goods from the 1C-enterprise to the Bitrix online store.
We chose the import method through commerceml files.
Everything, the goods are transferred, but they are transferred to a new infoblock. That is, a new one is created and everything is transferred there. How then to transfer these goods to the information block that is needed?

Answer 1

When creating a new IB, a unique external code is indicated in it, which corresponds to the uid from 1C. So that at the next import the goods are written not to the new IB, but to the one you need, take this external code from the new IB and transfer it to your IB.
