Hi Venki,
There are two options
1 Option ------- In SRM SOCO you have to add your fields in structure /SAPSRM/S_CLL_EXTENSION_FIELD
Option 2 ----
1. Extend the SC item with extra fields that you want, such as plant, if you haven't done that already, via SPRO
2. Enhance WebDynpro component /SAPSRM/WDC_DO_SOCO_GAF_1, view V_AO_SOCO_GAF_1. This step is to add the extra columns in the result table. This step has two sub-steps:
a. Context: add your extra fields under Context >> Search >> Result_Fields
b. Layout: Under "Table" node, add your extra columns with the same format as the other standard ones. And map the column/fields with newly added context nodes.
In the refresh method of class /SAPSRM/IF_CLL_DOM_SOCO_GAF1, it will bind.
Best regards,
Rohit
