Hi Dhruv,
You can implement BADI ME_PROCESS_PO_CUST  and implement the method FIELDSELECTION_ITEM.
I have pasted the SAP documentation available below. Please try this.
Field selection (FIELDSELECTION_HEADER_REFKEYS, FIELDSELECTION_ITEM_REFKEYS, FIELDSELECTION_HEADER, FIELDSELECTION_ITEM methods)
In the following methods, you can change the display properties of fields by supplementing or switching the field selection reference keys:
At header level FIELDSELECTION_HEADER_REFKEYS
Documentation for BAdI method FIELDSELECTION_HEADER_REFKEYS
At item level FIELDSELECTION_ITEM_REFKEYS
Documentation for BAdI method FIELDSELECTION_ITEM_REFKEYS
You can implement special rules using the methods FIELDSELECTION_HEADER (at header level) and FIELDSELECTION_ITEM (at item level).
Documentation for BAdI method FIELDSELECTION_HEADER
Documentation for BAdI method FIELDSELECTION_ITEM
Special Field Selection Item
Functionality
The FIELDSELECTION_ITEM method enables you to influence the field selection properties for a field.
Parameters
The following parameters are available:
IM_HEADER - Document header
The interface reference is of the type IF_PURCHASE_ORDER_MM.
IM_ITEM - Document item
The interface reference is of the type IF_PURCHASE_ORDER_ITEM_MM.
CH_FIELDSELECTION - Fiele selection table
By making changes to this table, you can influence the display properties of a field.
This table consists of value pairs <METAFIELD|FIELDSTATUS>.
The Metafield represents a business content (e.g. the PO quantity). Thus, for example, the database field EKPO-MENGE is linked to a certain metafield value just like the field MEPO1211-MENGE on the item overview screen in the purchase order.
Through this abstraction, reference can be made to business contents on a uniform basis.
Standard metafields are defined in the type group MMMFD.
The field selection status has four possible instances:
'-' Field is suppressed
'*' Field is purely a display field
'.' Input field
'+' Mandatory field
Notes
Under no circumstances make any changes to the database within this method. On no account use Commits.
For WBS element the meta filed no is 512.
mmmfd_wbs_element     TYPE mmpur_metafield VALUE 512.
In IF_EX_ME_PROCESS_PO_CUST~FIELDSELECTION_ITEM method you can write the code as follows:
field-SYMBOLS : <FIELDSEL> like line of ch_fieldselection.
DATA: l_persistent TYPE mmpur_bool.
l_persistent = im_ITEM->is_persistent( ).
READ TABLE ch_fieldselection ASSIGNING <FIELDSEL> WITH TABLE KEY metafield = '512'.
IF sy-subrc IS INITIAL.
  <FIELDSEL>-fieldstatus = '*'. " Field is purely a display field
ENDIF.
Try this, it should work.
Regards,
Savitha
