Need to Display DIR of material for PO's line item without PR in ME22n.

Hi All,

I get the task to display DIR of material(from DRAW) for line item of po having no reference PR in me22n.Currently DIR of material works only for line item with reference PR.

I found a BADI which triggers when u click DIR button for a line item,BADI DOCUMENT_MAIN01.But iam not sure which method to use and how,i check the method ~document_version_all but when iam passing value (in debug mode) its getting reset(no values in output).I found its using 'DOCUMENT_ASSIGNMENT' fm,so is there a way to do enhacement for this FM? or ANy other solution?

THANKS in advance,

Regards,

abhijeet.
