If outbound delivery for STO is created using BAPI- BAPI_OUTB_DELIVERY_CREATE_STO, it is not possible to populate value in few fields of header of delivery document (eg.-to display values in administration tab & Shipment tab) by simply passing values in the export parameters and table parameters of BAPI.
For the values to be populated in delivery header, Badi LE_SHP_DELIVERY_PROC is to be implemented and method FILL_DELIVERY_HEADER is used to populate details of delivery .
The method is called during delivery creation, each time that a new delivery header is filled with data. This method can be used to populate your own delivery header fields.
For displaying the desired values in delivery header tabs in delivery document, those values needs to be populated in CS_LIKP.
If these values are coming through any interface (idoc),then it should be exported from the corresponding function module or program and imported inside method FILL_DELIVERY_HEADER using import statement. This values in turn will be used to fill CS_LIKP to populate the delivery header.
The structure of CS_LIKP is same as LIKP.
One can update header fields using method-FILL_DELIVERY_HEADER, which could not be updated using parameters of BAPI-BAPI_OUTB_DELIVERY_CREATE_STO.
For example- For displaying value in ext.delivery in administration tab and TrnsID code in shipment tab, populate CS_LIKP-LIFEX and CS_LIKP-TRAID.Data can be used using VL03n-->click on header details icon .
Similarly, for item level data method- FILL_DELIVERY_ITEM can be used.
