ICubeMetaLoaderBindingParser.SkipList

Syntax

Description

The SkipList property returns the strings array that determines values that will not be loaded.

Example

Executing the example requires a time series database with the OBJ_FC identifier and the time series export file C:\Fixed.xlsx. Also, the repository must contain an MDM repository with the MDM_REPO identifier. This repository should have dictionaries with the DICT_CTR, DICT_IND and UNITS identifiers. The COUNTRY attribute of the time series database refers to the DICT_CTR dictionary, the INDICATOR attribute is a link to the DICT_IND dictionary, and measurement units refer to the UNITS dictionary.

The C:\Fixed.xlsx file, for which the example is created
