Update CATSDB table using BADI PT_ABS_REQ

Hello Experts,

Can we update the CATSDB table using IF_EX_PT_ABS_REQ~POST_VIA_BLOP method of the class CL_PT_ARQ_REQ_EXIT which is implemented in the BADI  PT_ABS_REQ.

*---Call BLoP to fill TMW buffer and add messages to message handler
   call method cl_pt_arq_badi=>blop_maintain_timedata
     exporting
       im_check_mode       = 'X'
       im_collect_messages = 'X'
     importing
       ex_cannot_post      = ex_cannot_post
     changing
       ch_blop_tab         = lt_blop_tab.

The internal table lt_blop_tab is of table type TIM_TMW_BLPREQUEST_ENTRY contains the CATS structure.

Can any one help me how to update CATSDB in this BADI.....

Thank you,
