    Hi,

    Communication structure means the mode in which you are guiding system to perform certain objective.

    Generally for releasing of internal or external Purchasing document this structure is used.

    CE- Communication structure Table- EKKO = Releasing of External purchasing document. Only applicable to Header document

    as table self explain that it will applicable to header only not the EKPO which is POu2019s Item details table.

    CEBAN u2013 Purchase requisition

    CE- Communication structure. EBAN u2013 Table name for Purchase requisition This is both at header & level release is possible.

    Regards

      Easiest definition I came across:

      A table is a table that has been created in the database.
      
      A structure is just a list of fields defined under a name. Structures are useful for painting screen
       fields, and for manipulating data that has a consistent format defined by a discrete number of fields.
      
      There is no content to view in a structure. You can, however, view the definition of a structure in SE11.

      It's a method for storing a limited sub-set of data for a given object e.g. for a Purchase Order, which means it is not necessary to reference the original tables. It's a method that gives greater clarity and efficiency and that provides information that can be used by a number of subsequent functions, for example the Information Structures, Release Strategies.

    Hi,

    Structure means:

    A structure (structured type) consists of components (fields) whose types are defined.

    Structures are used especially to define the data at the interface of module pools and screens and to define the types of function module parameters.

    Communication Structure:

    This is have possible fields for Release strategy to release the Pur. doc.

    Hi,

    Communication Structure

    Definition

    The communication structure is localized in the SAP Business Information Warehouse and displays the structure of the InfoSource. It contains all of the InfoObjects belonging to the InfoSource of the SAP Business Information Warehouse.

    Use

    Data is updated in the data targets of this structure. In this way, the system always accesses the actively saved version of the communication structure.

    In the transfer rules maintenance, you determine whether the communication structure is filled with fixed values from the transfer structure fields, by means of a formula or using a local conversion routine.

    Conversion routines are ABAP programs that you can create yourself. The routine always refers to just one InfoObject of the transfer structure.

    The communication structure to be maintained can be taken from table T681Z. Table T681Z can be displayed with Transaction SE16. Use 'B' for message determination and application EF for purchase order. The structure for purchase order communication is KOMKBEA.

    Procedure:

    Include field ZZ<field> in the communication structure KOMKBEA. In this structure there is an include that is provided for additional fields. In this Include KOMKBZ you must include the field with the name ZZ<field>.

    The same field must also be included in structure KOMB in Include KOMBZ (the same procedure as under point 1).

    In table T681F use Transaction SM31 with key B, EF to add the same field. As of Release 4. 0 you can use view V_T681F in Transaction SM30 for that purpose. Enter usage 'B', your application and field group '001'.

    In the message determination, the system runs perform USEREXIT_KOMKBEA_FILL. This perform is in program RVCOMFZZ.

    The source code should be changed as follows:

    FORM_USEREXIT_KOMKBEA_FILL.

    COM_KBEA-ZZ<feild> = <field-value>.

    ENDFORM.

    Any EKKO field with the following syntax can be used. COM_KBEA-ZZFIELD1 = COM_EKKO-field.

    After making this change, you must create a new condition table and an access sequence that contains the new field. If a new access sequence and condition table have already been created before changing the communication structure, this must now be deleted again.

    Points 1 to 5 must be carried out in sequence.

    Note that the syntax check in Include RVCOMFZZ can deliver errors. Check the entire function group (according to Note 2152).
