Hi,
The seven characteristic values are as follows:
' ': The record delivers an after image.
The status is tranferred after something is changed or added. You can update the record into an IncoCube only if the corresponding before image exists in the request.
'X': The record delivers a before image
The status is transferred before data is changed or deleted.
All record attributes that can be aggregated have to be transferred with a reverse +/- sign. The reversal of the sign is carried out either by the extractor (default) or the Service API. In this case, the indicator 'Field is inverted in the cancelation field' must be set for the relevant extraction structure field in the DataSource.
These records are ignored if the update is a non-additive update of an ODS object.
The before image is complementary to the after image.
'A': The record delivers an additive image.
For attributes that can be aggregated, only the change is transferred. For attributes that cannot be aggregated, the status after a record has been changed or created is transferred. This record can replace an after image and a before image if there are no non-aggregation attributes or if these cannot be changed. You can update the record into an InfoCube without restriction, but this requires an additive update into an ODS Object.
'D': The record has to be deleted.
Only the key is transferred. This record (and its DataSource) can only be updated into an ODS Object.
'R': The record delivers a reverse image.
The content of this record is the same as the content of a before image. The only difference is with an ODS object update: Existing records with the same key are deleted.
'N': The record delivers a new image.
The content of this record is the same as for an after image without a before image. When a record is created, a new image is transferred instead of an after image.
The new image is complementary to the reverse image.
The table RODELTAM determines which characteristic values a delta process uses (columns UPDM_NIM, UPDM_BIM UPDM_AIM, PDM_ADD UPDM_DEL and UPDM_RIM). The table ensures that only useful combinations of the above values are used within a delta process.
When extracting in the 'delta' update mode in the extracted records for the indicator, a DataSource that uses a delta process can deliver only those characteristic values that are specified in the delta process.
