Change Part
The following API structure tables list all the APIs and the respective API fields that are required to change a material master record within the current version of SAP. These APIs are listed in the order in which they are invoked.
BAPI_MATERIAL_SAVEREPLICA
This API is used to change all the material data in SAP. It should be called for each material to be changed in each plant. The API does not process multiple materials in multiple organizations with one API invocation.
All data is not sent for a change so that data maintained by the distribution target user is not overwritten. The following table provides details on this API.
* 
The BAPI_MATERIAL_SAVEREPLICA function passes data in English. Additional characterization is required to render other supported languages.

CCAP_REV_LEVEL_MAINTAIN
This API creates a new revision level for the material changed with BAPI_MATERIAL_SAVEREPLICA. The revision level creation is tracked with a change number defined from Windchill PDMLink. The change master record for the change number must exist in SAP before running this API. The following table provides details on this API.

CALO_INIT_API
This API should be invoked before the CCAP_REV_LEVEL_MAINTAIN API is called to update a part revision level. It is not necessary to pass any data into this function module. The defaults written into the API when it is done executing meet theWindchill ESI requirements. The following table illustrates the defaults passed in automatically upon execution of this API and provides details on it.

BAPI_TRANSACTION_COMMIT
This API is used to commit a transaction to the SAP distribution target. If the return message generated from the BAPI_MATERIAL_SAVEREPLICA execution is a success, then this API is executed.
When this API is executed, all part data, sent from Windchill PDMLink, is committed to the MARA and MARC (if plant data sent) SAP database tables.
For more information on howWindchill ESI interprets the results of the SAP API calls, see the Windchill Enterprise Systems Integration Customizer's Guide - SAP.
* 
No data is passed through the BAPI_TRANSACTION_COMMIT function module but it is necessary to call the module to release the material in the event that invalid data is passed through. Refer to theWindchill Enterprise Systems Integration Customizer's Guide - SAP for an explanation of how SAP APIs are called in sequence to execute eachWindchill ESI business function.

BAPI_TRANSACTION_ROLLBACK
This API is used to rollback a transaction to the SAP distribution target. This API is executed if the return message generated from the BAPI_MATERIAL_SAVEREPLICA function is not a success. When this API is executed, all part data sent fromWindchill PDMLink is rolled back and if plant data is sent, not committed to the MARA and MARC SAP database tables. Refer to theWindchill Enterprise Systems Integration Customizer's Guide - SAP for an explanation of howWindchill ESI interprets the results of the SAP API calls.
* 
No data is passed through the BAPI_TRANSACTION_ROLLBACK function module but it is necessary to call the module. For more information on how SAP APIs are called in sequence to execute eachWindchill ESI business function, see the Windchill Enterprise Systems Integration Customizer's Guide - SAP.
