BAdI Implementation
Context-based masking can be achieved by implementing Masking BAdI /UIM/BD_SEARCH_HELP_MASK
Create BAdI implementation for method /UIM/IF_SEARCH_HELP_MASK~PREPARE_MASK_DATA
Sample code is given below –
*-- Loop the record table to read the sales org
LOOP AT ct_record_tab ASSIGNING <fs_mask>.
*-- check the sales org and if it is not 1000
*--then unmask distribution channel, division, sales office and sales group
IF <fs_mask>+3(4) NE '1000'.
READ TABLE it_record_tab ASSIGNING <fs_unmask> INDEX sy-tabix.
IF sy-subrc EQ 0.
<fs_mask> = <fs_unmask>.
ENDIF.
ENDIF.
ENDLOOP. Conclusion
