How to add custom field in Documents Tab of PO Header ?

Question

Dear SRM Friends,
  This is a challenging task as an ABAPer to confront to..
  We are in the midst of a requirement where we have to add a custom field in the PO Header. But the requirement is to add the field in Documents Tab in PO Header Data as found in the following path of SRM Webpage  :
Operational Purchaser > Purchase Orders > Process Purchase Order > Select a PO > Header Data > Documents.
  As guided by "Note 672960 - User-defined fields 2" , on executing all the steps of the note the field is getting added, but in the Basic Data Tab of the PO. But this doesnt meet the client requirement.
  Anybody having some solution to this, shall be greatly awarded.
Thanks in advance,
Vikas.

Hi Vikas,
You can define a Text ID in Header data with F4 help. But the list of values will be fixed, but configurable. This will exactly solve your problem. This will be quite simple and straight forward solution with no custom developments.
Please Navigate to
SAP Implementation Guide -> Supplier Relationship Management -> SRM Server
-> Cross-Application Basic Settings -> Text Schema
1. Define Text Types
Select BBP_PD and double click text id. Add a new text id here.
2. Define Text Schema
Select PO and add the newly created text id and set required parameters.
3. Define Fixed Values for Texts
Select your PO transaction type and maintain the required values for F4 help / drop down.
Hope this would solve your problem.
