The Deployment Logic

Create your custom program

Define Field Catalog, Define Style table , Define Data Tab and include style table in this.

In fieldcatalog pass Edit Parameter checked for which column output should editable. Pass style into data table and call Function Module

On output you will find a single row based on condition editable.

Steps involved The step that needs to be followed is as below. below. 1. Go to Se 37 , Create Create a Function Function module module based based on your your naming naming convent convention ion .

Define in Top data . DATA: LS_EDIT TYPE LVC_S_STYL, LT_EDIT TYPE LVC_T_STYL.

Define : HANDLE_STYLE TYPE LVC_T_STYL, "FOR DISABLE In your data tab. e.g- it_vbap is data tab.where tab.where 2 fields for data vbeln,posnr vbeln,posnr . so added handle_style into data tab. e.g.

DATA: BEGIN OF IT_VBAP OCCURS 0, VBELN LIKE VBAP-VBELN, POSNR LIKE VBAP-POSNR, Flag, HANDLE_STYLE TYPE LVC_T_STYL, "FOR DISABLE END OF IT_VBAP.

2. In imp impor orti ting ng para paramet meter er Pas Passs FLAG a mandatory Flag to and mention default value 1 for 167 infotype . As shown blow. LOOP AT IT_VBAP INTO LS_OUTTAB WHERE FLAG = 'X'. V_INDEX = SY-TABIX.

LS_EDIT-FIELDNAME = 'VBELN'. LS_EDIT-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENAABLED. LS_EDIT-STYLE2 = SPACE. LS_EDIT-STYLE3 = SPACE. LS_EDIT-STYLE4 = SPACE. LS_EDIT-MAXLEN = 8. INSERT LS_EDIT INTO TABLE LT_EDIT. LS_EDIT-FIELDNAME = 'POSNR'. LS_EDIT-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED.
