Create CN
The following API structure tables list all the APIs and the respective API fields that are required to create CNs within the current version of SAP distribution targets. These APIs are listed in the order in which they are invoked.
CCAP_ECN_CREATE
This API creates a CN in SAP. It is characterized to create a CN that is valid for the create or change functions of documents, BOMs, and materials. It is also characterized to list material objects on the CN with alternate effective dates set to the current date. The Header Effective is initially set to a future Effective Date and the CN status is set to Active.
BOMs and Documents are not listed on the CN as part of the CN create process. Instead, they are listed on the CN when the CN is used to create or change these object types.

1. The fields ALT_DATE and VALID_FROM are intentionally defaulted to the same value.
CCAP_ECN_MAINTAIN
This API is used to change a CN in SAP. This API is called after the CN is created and used in creating or changing BOMs or documents. The API is used to create alternate dates and assign those alternate dates to the document and BOM objects that are listed on the CN. Additionally, this API is used to set the CN header effective date value to the current date and set the CN status to inactive.
The following table provides details on this API.

1. These default values are not included here because they have been included in the default tables of either the Document or BOM functional designs.
2. The fields ALT_DATE and VALID_FROM are intentionally defaulted to the same value.
3. Object Management Records only need to be created for the documents and BOMs listed on the CN.
CALO_INIT_API
This API should be invoked before the CCAP_ECN_CREATE and CCAP_ECN_MAINTAIN APIs are called to create an ECN or update its effectivity dates. 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.
