Hi
Enhancement means in the SAP given datasource If you want to add extra fields.
The procedure is like below.
Take the datasource in which you enhance.
1. If you enhancing in the LO datasaource, take the aprapriate communication strucute append the structure in that structure add the fields you wnat enhance.
If you are enhancing other than LO you take extract structure append the structure and add the fields in that structure.
2. Goto LBWE Tcode take the option called "Maintain Extract structure" take the fields which you enhanced from pool take push in to extract strucure.
If you enhancing other than LO no need to do this.
3. Goto RSA6, take datasource, goto change mode. The enhanced fields Hide option checked, reomove that tick and save it.
4. Goto "CMODE" tcode, If project is already created for that enhancement goto disply mode. If the project is not created give the project name created and give the enhancemet name as "RSAP0001" and save it.
in the component you can find 4 Function modules
EXIT_SAPLRSAP_001 -> Transaction Data
EXIT_SAPLRSAP_002 -> masterdata attributes
EXIT_SAPLRSAP_003 -> Master data Texts
EXIT_SAPLRSAP_004 -> Masterdata Hirarchies.
Take the apprapriate FM and double click on it
there you can find Include name. If you double click on it you can find ABAP editor.
there we have to write the code
example code will be like below.
data: l_s_icctrcst like icctrcst,
l_s_icctract like icctract,
l_s_icctrsta like icctrsta,
l_tabix like sy-tabix.
case i_datasource. */ in BW 1.2B case i_isource.
when '0CO_OM_CCA_1'.
loop at c_t_data into l_s_icctrcst.
l_tabix = sy-tabix.
select single * from z0001 where kokrs = l_s_icctrcst-kok
and kostl = l_s_icctrcst-kostl.
if sy-subrc = 0.
l_s_icctrcst-zfield1 = z0001-zfield1.
l_s_icctrcst-zfield2 = z0001-zfield2.
modify c_t_data from l_s_icctrcst index l_tabix.
endif.
endloop.
when '0CO_OM_CCA_2'.
when '0CO_OM_CCA_3'.
when others.
exit.
endcase.
This is example code.
