Hello gurus,

Can someone tell me what are the modes and the functionality for an ODS. Like what are the record modes and how do you check what is used when.

Thank you

    Record modes of ODS are:

    The various values are as follows:

    ' ': The record delivers an after image.

    The status is transferred after something is changed or added.

    'X': The record delivers a before image.

    The status is transferred before data is changed or deleted.

    'A': The record delivers an additive image.

    For attributes that can be aggregated, only the change is transferred.

    'D': The record has to be deleted.

    Here only the key is transferred.

    'R': The record delivers a reverse image.

    The content of this record is the same as the content of a before image.

    'N': The record delivers a new image.

    When a record is created, a new image is transferred instead of an after image. The content of this record is the same as for an after image without a before image.

    If a Data Source implements a delta process that uses several characteristic values, the record mode must be a part of the extract structure and the name of the corresponding filed must be entered in the Data Source as a cancellation field (ROOSOURCE-INVFIELD). This you can go and check in ROOSOURCE table.

    The table RODELTAM determines which characteristic values a delta process uses. When extracting in the 'delta' update mode in the extracted records for the record mode, a Data Source that uses a delta process can deliver only those characteristic values that are specified in the delta process.
