Analytic Type Supplement Info

All analytic types derive their value from the value of another data item. This requires the name of the object in which the data item is located and its reference. If the object name is one of the built-in identifiers: src, parent, or parent_src, it may be necessary to provide a more specific identification of the object referenced by the identifier.
On that account, wherever an analytic type references its source data, it contains, in addition to the object name and data reference, also analytic type supplement info with the following contents:
Object Name
Description
src_id
Applicable to the src object name in inferred sequences with multiple sources: determines the sequential number of the source sequence in which the source element is located. Source sequences are numbered from 0.
parent_src_id
Applicable to the parent_src object name in inferred sequences with multiple sources: determines the sequential number of the source sequence in which the source element is located.
parent_skip
Applicable to the parent and parent_src object names: determines how many sequences superior to the nearest superior sequence should be skipped to locate the required element. If the value is 0, the object name identifies an element of the sequence superior to the nearest superior sequence. (That is, not the nearest superior, but the one immediately above it).
Analytic type supplement info has no significance for other object names.
In the vast majority of situations, you will not need to specify the analytic type supplement info yourself because the application generates it during table operations such as grouping or ungrouping.
