Functionality
This function module is the task API for defining the classic APIs. Thisapplies to new extensions for the application object, Business PartnerRelationship (BUPR), generated through the Easy Enhancement Workbench(EEW).
In the case of BUPR for the cardinality types 1:1 and 1:N, this task APIdefines the following objects:

• Function group, which holds the generated APIs


• Includes


• APIs, which are of the following types:

Get - This API retrieves the details of the extension that isvalid for a specified date.
GetList - This API reads the details of the extension for aparticular time interval.
Add - This API adds a record to the extension.
Change - This API updates the changes made to the attributes ofan extension.
Maintain_Period - This API should be called, in the case of timedependent extensions, when you add or change the records, which resultsin the merging, shrinking or deletion of existing records.
Maintain_All - This API should be called, in the case of timedependent extensions, in scenarios such as data exchange and massupdate. This API should be called to perform operations such ascreation, modification, deletion of records simultaneously for anextension.
Remove - This API deletes the record in an extension that isvalid for a specified date.
MemoryInit - This API initializes the memory.
UpdateServices - This API saves the data to the database.
Callback - This API retrieves the data from the memory. In theBDT scenario, the API has to retrieve data from the BDT memory. Sincethe BDT memory is different, a new API is available in the BDT, which iscalled by the Callback API to retrieve data from BDT memory.

• Include structure - The Get and GetList APIs retrieve data
in the format of this structure. This structure will not have the ParentObject Key fields.

• Key structure, which contains the key fields of the table excluding the
Parent Object Key fields.

• Data structure, which contains all the non key fields of the table.


• DataX Structure


• Structure for data exchange, which has to be appended to the complex
structure BUS_EI_EXTERN for data exchange. This structure has thefollowing format for both 1:1 and 1:N extensions:
Field,,Description
CURRENT_STATE,,Indicator for complete data
TIME_DEPENDENT,,To determine if data is coming from time dependent ortime independent system
XXX_DATA,,Data that is coming from another system
The field XXX_DATA has the format XXX_TABLE_LINE structure.XXX_TABLE_LINE structure has the following format:
Field,,Description
TASK,,Change Indicator Object
DATA_KEY,,Key Field Structure
DATA,,Search Structure
DATAX,,Change Structure
CURRENTLY_VALID,,Determines if data is valid today
Note: XXX is determined by the task API.
The Classic API task API reads the following entries of the tableCT_TASKPARAMLIST:
Parameter Name,,Description
TABL,,Name of the generated table
FIELD,,Name of the field for the generated table. All fields of thetable use this parameter. This parameter is the child of the TABLparameter.
ISKEY,,Key field information of the field. This parameter is the childof the FIELD parameter.
DTEL,,Name of the data element for the field. This parameter is thechild of the FIELD parameter.
PARENT_KEY,,Parent key information of the field. This parameter is thechild of the FIELD parameter.
Note: The value of the parameter PARENT_KEY is marked as 'X' forparent key fields.
STRUC_CHD,,Details of the new structure for change document. Thisparameter is the child of the TABL parameter.
APICHECKFUNC,,Name of the Check table function module. Thisparameter is the child of the FIELD parameter.
APIUPDATE,,Name of the Update API. This parameter is the child ofthe TABL parameter.
The task API reads the following entries of Applications KnowledgeBase table (OXT_ER_KNOWLEDGE) for the time validity of the extension:
Node1,,Node2,,Parameter Name,,Description
APIGEN,,DATA_ELEMENT,,DATEFROM, DATETO,,When a new field is addedthrough the knowledge base, the data element of the field has to bementioned for the generation of APIs.
The Classic API task API updates the:

• Table CT_GOX_HEADER with the details of the objects to be
generated

• Table CT_TASKPARAMLIST with the following information:

Parameter Name,,Description
FUNCTION_GROUP_API,,Name of the function group containing all the APIs.This parameter is the child of the TABL parameter.
APIGET,,Name of the Get API. This parameter is the child of theTABL parameter.
APIGETLIST,,Name of the GetList API. This parameter is the childof the TABL parameter.
APIADD,,Name of the Add API. This parameter is the child of theTABL parameter.
APICHANGE,,Name of the Change API. This parameter is the child ofthe TABL parameter.
APIMAINTAIN,,Name of the Maintain_Period API. This parameter isthe child of the TABL parameter.
APIMAINTAINALL,,Name of the Maintain_ALL API. This parameter isthe child of the TABL parameter.
APIREMOVE,,Name of the Remove API. This parameter is the childof the TABL parameter.
APIMEMINIT,,Name of the Memory Init API. This parameter is thechild of the TABL parameter
APIUPDSERVICE,,Name of the Update Services API. This parameter isthe child of the TABL parameter.
FUNC_CALLBACK,,Name of the Callback API. This parameter is thechild of the TABL parameter.
APIMEMORYGET,,Name of the API in the BDT, which is called by theCallback API to retrieve data from the BDT memory. This parameteris the child of the TABL parameter.
STRUC,,Name of the include structure. This parameter is the child of theTABL parameter.
STRUC_KEY,,Name of the ey structure. This parameter is the child of theTABL parameter.
STRUC_API,,Name of the data structure. This parameter is the child ofthe TABL parameter.
STRUC_UPD,,Name of the dataX structure. This parameter is the child ofthe TABL parameter
STRUC_MEM,,Memory structure name
STRUC_DX_TABLE,,Name of the data table type for data exchange. Thisparameter is the child of the STRUC_DX parameter.
STRUC_DX_LINE_TYPE,,Name of the data structure for data exchange. Thisparameter is the child of the STRUC_DX_TABLE parameter.
