Functionality
This function module is the task API to define the objects for dataexchange between systems. This applies to new extensions for theapplication object, Business Partner (BUPA), generated through the EasyEnhancement Workbench (EEW).
In the case of BUPA for the cardinality types 1:1 and 1:N, this task APIdefines:

• The outbound function module


• The inbound function module


• A function module to read the data from the extension table, if you are
transferring data to a time independent system

• A function module to create entries for table BUT_TDTRANS

The task API reads the following entries of the tableIT_EXTENSIONDEF:
Parameter Name,,Description
CARDINALITY,,Cardinality (1:1 or 1: N) of the extension
TIME_DEPENDENCY,,Time dependency (time dependent or time independent) ofthe extension
TIME_CONSTRAINT,,Time constraint (With Gaps, No Gaps or Time Validity)of the extension
The task API reads the following entries of the tableCT_TASKPARAMLIST:
Parameter Name,,Description
APPLI,,Application name for the extension
TABL,,Name of the generated table
STRUC_KEY,,Key structure of the generated table
STRUC_API,,API structure of the generated table
STRUC_UPD,,Update structure of the generated table
STRUC,,Read structure of the generated table
CHDOC,,Change document structure name
FUNC_CALLBACK,,Name of the Callback API
APIGETLIST,,Name of the GetList API
APIMAINTAIN,,Name of the Maintain_Period API
APIMAINTAINALL,,Name of the Maintain_All API
APIADD,,Name of the Add API
APICHANGE,,Name of the Change API
APIREMOVE,,Name of the Remove API
The task API reads the following entries of the ApplicationsKnowledge Base table (OXT_ER_KNOWLEDGE):
Node1,,Node2,,Parameter Name,,Description
DDICGEN,,INCLUDEFIELD,,DATEFROM,,Name of the date from field
DDICGEN,,INCLUDEKEY,,DATETO,,Name of the date to field
CODEGEN,,OBJECTINFO,,%OBJECTIDENT1%,,Name of the Partner field
DDICGEN ,,MAINDX_STRUC ,,APPEND_DX,,Name of the structure to which thedx structure should be appended
The task API updates the table CT_TASKPARAMLIST with thefollowing entry:
Parameter Name,,Description
STRUC_DX,,Name of the Append structure appended to BUS_EI_EXTERNstructure
The task API makes the following table entries:
Table Name,,Entry
CRMC_BUT_CALL_FU,,Name of the inbound module
CRMC_BUT_CALL_FU,,Name of the outbound module
TB058,,Table name and change document structure name
TB058,,Name of the function module used for reading data from theextension table
TB058,,Name of the function module used for creating entries to beinserted into the table BUT_TDTRANS
The task API updates the table CT_GOX_HEADER with the followingdetails:

• Inbound function module name


• Outbound function module name


• Function group name


• Function module name, which is generated if you are transferring data to
a non time dependent system
Note: The Data Exchange task API does not update the tableCT_TASKPARAMLIST with any information.
