After invoking the BAPI_MATERIAL_BOM_GROUP_CREATE, BAPI_TRANSACTION_COMMIT should be invoked using the same session id.
CALO_INIT_API
This API should be invoked before the CSAP_MAT_BOM_MAINTAIN is called to change a BOM. 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.
