There is a need to load a large volume of data from an external system into ERP — 5-7 million records per month. Where is it better to record: in the document's tabular part, in the information register, or in the directory?

For uploading a large volume of data (5-7 million records per month) into 1C ERP, it is better to use a information register.

Why specifically an information register?

• Information registers are designed for storing large volumes of data with efficient search and selection capabilities.
• Tabular parts of documents are not intended for storing millions of records, which can lead to performance and data management issues.
• Directories are suitable for storing reference information but not for such large flows of transactional data.

Thus, an information register will provide more optimal storage and processing of large data volumes, as well as enable the use of indexing mechanisms and periodic updates.
