Method CHECK_NEGATIVE

Function

Method IF_UKM_ID_DICTIONARY~CHECK_NEGATIVE checks if there is a negative mapping between two keys. The method is mass-enabled, that is multiple pairs of keys can be checked for negative mappings with one call.

Parameters

Type	Name	Description
Import	IV_READ_BUFFER	This optional parameter defines whether to use data from the buffer. This data can contain unsaved information.
Import	IV_UPDATE_BUFFER	This optional parameter defines whether data read from the database is to be copied to the buffer. This speeds up subsequent read access to the same data.
Export	ES_MESSAGES	This parameter can contain a list of messages about processing. The row indexes of table CT_NEGATIVE_PAIRS correspond to the row indexes of the corresponding messages in subtable ES_MESSAGES-SPECIFIC_MESSAGES.
Changing	CT_NEGATIVE_PAIRS	This parameter is a table containing the pairs of keys to be checked. If the method finds a negative mapping, it sets the EXISTING field of the corresponding row to ABAP_TRUE.

Notes

Alternatively, you can use method GET_NEGATIVE to query negative mappings.
