Hello. In 1C is not strong.
There is a nomenclature in the database, it has a lot of additional details (1200+ pieces) and almost all (or even all) of the "Additional values" type. The task is to remove all additional details.
When deleting swears at the position of the nomenclature, the values ​​​​are used. I think to remove first the values ​​for all positions, then the additional values ​​themselves and then the additional details. But where to look for values ​​for items of the nomenclature?

Answer 1

Themselves extra details are stored in the "Additional details and information" feature type plan. Their additional values, in the reference book "Additional values". Binding extra. values ​​to the object goes through the tabular part "Additional Details".
