This blog describes how to use the EDW interfaces for Master Data update published in the SAP NetWeaver Developer Guide by using a example. The link to the guide can be found in my blog SAP NetWeaver BI Interfaces - Overview. (SAP NetWeaver BI Interfaces - Overview II (SAP NetWeaver BI Interfaces - Overview II)) The used example can update/insert a key and text of the master data stored in InfoObject 0VERSION. The sample will be easy to use from outside. A table of the texts can be easily updated. The returned message can be easily interpreted. The open interfaces used in this blog are the function modules: *BAPI_IOBJ_GETDETAIL
*and *RSNDI_MD_TEXTS_UPDATE* h5. Step by Step guide *Create a Function Group* In this example I have created the Function Groups ZGEN_WEBSERVICE in the ABAP Developer Workbench (Transaction SE80) [http://help.sap.com/saphelp_nw04s/helpdata/en/d1/801ef5454211d189710000e8322d00/content.htm | http://help.sap.com/saphelp_nw04s/helpdata/en/d1/801ef5454211d189710000e8322d00/content.htm]
0.1. *Create a reuseable INCLUDE 'ZGEN_TEXT'* that can be reused for any other InfoObject. Please find the coding of the Include ZGEN_TEXT below. This INCLUDE is NOT part of the Function Group ZGEN_WEBSERVICE. 
0.1. *Create a remote enabled function module* Z_TXT_SET_0VERSION The function module must be remote enabled. This can be flaged in the 'Attributes' view in the function module maintenance. 
" There are no Importing paramters necessary. The Exporting paramter is 'message' with type 'BAPI_MSG'. This is the message that will be sent back to the caller if the update of the text was succesful or not. 
" The Tables parameter defines the structure of the text table that will be updated. The text table of an InfoObject can be found in the InfoObject maintenance Master data/texts view in transaction RSD1. 
" In this case it is the table /BI0/TVERSION. 
There are no Exceptions defined. The source code of the function module is very simple since the include mentioned in 2. is very generic.

The WebService can be generated using the created the created function module.
