Get Time Data ID Type value entered after save in PTMW

I want to set an 'X' in PTM_DETAIL_INDEX-SPRPS depending on value captured in PTM_DETAIL_INDEX-TDTYPE in PTMW,

I have enhancements in include LPT_GUI_SAP_TMW_DETAILF50 at form  pbo_index and  pai_index, but I can't find value 'ABC'

any idea how can I read that value?

Thanks in advance,
