transaction CBIHM2 status change to "released" performance problems

Dear experts

we are facing a performance issue on some projects in transaction CBIHM2,

when are changing the status of a project to "RELEASED".

The performance issue is caused by logic going (for unknown reason) multiple times into risk management check

in

include: LCBIH_ER30F10

form: L_QTY_SET_EPQUANTSET

4.384         SELECT * FROM cciht_erh

4.385                INTO CORRESPONDING FIELDS OF TABLE l_riskass_iotab

4.386                FOR ALL ENTRIES IN i_api_erqtexist_tab

4.387                WHERE recn = i_api_erqtexist_tab-recnroot

4.388                  AND delflg = ' '

4.389                  AND ( ( valfr <= i_api_erqtexist_tab-valfr AND

4.390                          valto >= i_api_erqtexist_tab-valfr   ) OR

4.391                        ( valfr <= i_api_erqtexist_tab-valto AND

4.392                          valto >= i_api_erqtexist_tab-valto   ) OR

4.393                        ( valfr >= i_api_erqtexist_tab-valfr AND

4.394                          valto <= i_api_erqtexist_tab-valto  )  ).

We have similar projects without this issue and without this risk management check logic.

Could me anybody give a hint about this?

Thank you

Imrich
